Target Audience:The PI has been communicating regularly with one small scale near St. Louis and one large scale mushroom producer in Madisonville, TX and updating them about the progress made on this project. Several undegraduate and graduate students from biotechnology and mechnical engineering program at University of Houton are trained on mycology and mushroom cultivation. The completed research work are presented at vegetable conferences organized my Texas A&M AgriLife extension at Fort bend country in Texas. Changes/Problems:Due to the long lead time in receiving the incubators and substrate processing machines, some of the milestone's completion was delayed. Also, there were some delays in getting the approval for installing the shipping container testbed. What opportunities for training and professional development has the project provided?This USDA project has helped recruit and train undergraduate senior design students from mechanical engineering and capstone students from biotechnology programs and complete their research projects. It has also helped to recruit several Ph.D. and M.S. students to complete their thesis on producing and processing mycelium and mushrooms using newly developed methods and procedures. It also helped us receive an additional UH infrastructure grant to establish a permanent test that is best at UH to train and educate students and small-scale mushroom producers. Some of the capstone students have already completed their research projects, and a few newly recruited students are undergoing training in mushroom and mycelium cultivation. Thirteen undergraduate students with biotechnology majors have completed their capstone projects on mushroom and mycelium cultivation in the past three years, and three undergraduate students with mechanical engineering majors have completed a senior design project on composting spent mushroom substrate into fertilizers. Two M.S. student (Alessandro De La Garza from computer system engineering programand Mengchuan Zhuang from Biotechnology) defended his M.S. thesis on the topic 'Estimating Mushroom Yield and Quality Using Computer Vision ' and 'Sequence Annotation of Edible Fungus Calocybe indica Using Different Bioinformatics Tools' in May 2021 and May 2023 respectively. Three M.S. students are currently undergoing training to produce and process mushrooms to biomaterials and medicinal compounds. Two Ph.D. students (Sandesh Risal, and Ezra Wari) from Mechanical engineering program have completed their research work 'Modeling small scale mushroom cultivation in shipping containers', and Two Ph.D. students (Mahsa Alian from Environmental Engineering and Pratikshya Tiwari from Mechanical Engineering) are working on developing 'Methods to produce carbon neutral mycelium cultivation and energy calculations'. Another Ph.D. student (Srinandhini Chandran) is working on evaluating the effects of mushroom extracts on immune modulation and anticancer properties. How have the results been disseminated to communities of interest?For this funding period, we have published two research papers and two conference papers. In addition, we have submitted one conference paper. We are in the process of writing five other manuscripts that will be submitted to various peer-reviewed scientific journals for publication. We have developed a website to disseminate our research findings to mushroom-growing communities and presented some of our research findings at the recently held Prairieview A&M University Ag Day (April 2024) and 39th annual Fort Bend Regional Vegetable conference organized by the Texas A&M AgriLife extension at Fort bend county fairgrounds, Rosenberg, TX (February 2024). Over 200 farmers participated in these two events. The PI has been communicating regularly with one small scale near St. Louis and one large scale mushroom producer in Madisonville, TX and updating them about the progress made on this project. What do you plan to do during the next reporting period to accomplish the goals?We have received a one-year no-cost extension for this project. In the fourth year, we look forward to installing the new testbed comprising two 40-ft. shipping containers at the UH Sugarland campus that will have several infrastructures such as a substrate processing room, inoculation room, and mushroom-producing rooms with a proper control system. This will help us train high school, undergraduate, and graduate students. We will organize a two day workshop for small-scale mushroom producers with hands-on experience and necessary training materials in summer 2024. We will complete several ongoing mushroom and mycelium cultivation projects and submit the final report.

What was accomplished under these goals?
Update on the shipping container test best: The UH Facilities Department approved installing two 40-foot shipping container testbeds, expected to be commissioned by the end of Summer 2024. Despite initial logistical delays, the installation will proceed, and the previously ordered substrate processing system will be commissioned. This system includes a steam generator, milling machine, substrate mixer, and densification unit, essential for substrate sterilization, particle size reduction, nutrient incorporation, and compacting. These testbeds will significantly advance our project by providing a controlled environment to refine methods, informing future scale-up efforts, and developing efficient, sustainable practices for small-scale urban mushroom farming. This initiative aims to enhance productivity, reduce waste, and promote urban agriculture viability. Determining the sterility of biomass after conditioning: We developed methods using an ATP measuring kit, culture plate, and metagenomic analysis to test biomass sterility after steam conditioning and hydrogen peroxide treatment. A 4% hydrogen peroxide concentration for 1 hour matched the fungal colonization rates of steam sterilization. We are assessing mushroom yield, economics, and energy savings using hydrogen peroxide for substrate conditioning. Collaborating with Dr. Jayshankar Timuluru from the USDA-ARS, we will evaluate the sterility of densified cotton gin waste pellets, then hydrate and inoculate them with fungal mycelium. In the project's fourth year, we will assess mushroom growth and yield and develop a logistics model for producing and packaging sterilized biomass. This approach simplifies the production process for small-scale mushroom producers. Simulation model for energy consumption in mushroom substrate composting: We've developed a simulation model for a large-scale mushroom farm to optimize energy use during composting. This model assesses energy requirements for various stages of substrate processing, integrating data from literature on equipment specifications. By simulating stochastic energy consumption, we estimate the energy needed for compost production and compare it with existing data. This analysis informs lifecycle and techno-economic evaluations, guiding process refinements to enhance efficiency and reduce resource usage. Carbon-neutral method of producing mushrooms and mycelium: Traditional mushroom cultivation relies on lignocellulosic biomass, which releases a pound of CO2 for every pound of mushroom produced. This research investigated using algae as an alternative substrate to increase productivity and reduce carbon emissions by capturing the carbon using macroalgae. The study focused on four mushroom species: ELM oyster (Hypsizygus ulmarius), milky white (Calocybe indica), oyster (Pleurotus ostreatus), and reishi (Ganoderma lucidum). Various microalgae, such as Chlorella, Spirulina; and macroalgae such as Dulse, Nori, were tested alone or with lignocellulosic biomass. Substrates mixed with 10% dry-weight algae were autoclaved and poured into Petri dishes, with plain agar and PDA as controls. Results showed that algae substrates varied in effectiveness among species. H. ulmarius grew over twice as fast while C. indica showed a 5.4-fold and 4.9-fold increase on Nori and Dulse, respectively. P. ostreatus performed better on microalgae, doubling growth when combined with macro- and microalgae. G. lucidum showed a 5-fold increase when algae were combined with lignocellulosic biomass. Experiments in glass jars confirmed these findings, with pure macroalgae substrates forming fruiting bodies in 10-days and mixed substrates in 2-weeks, compared to 4-5 weeks for lignocellulosic biomass alone. This research demonstrates that algae can be an effective alternative substrate, enhancing mycelium growth rates and yields and reducing cultivation times. The findings suggest significant potential for industrial-scale applications, offering faster growth and higher yields, making cultivation more cost-effective and resource-efficient. This research lays the foundation for further optimization of algae-based substrates, promising significant advancements in climate-smart mushroom production. We will be publishing a manuscript summarizing this work. Modeling Urban Small-scale Oyster Mushroom Farm using Shipping Containers: ?This study investigates the use of shipping containers for small-scale urban mushroom farming, emphasizing space optimization and continuous production. It compares three substrate packing methods (bottles, bags, and buckets) and designs container-based farm layouts for daily production levels of 50, 100, and 250 pounds of oyster mushrooms. Using SOLIDWORKS CAD modeling, the most efficient method was found to be the bag method, yielding 2,800-3,750 lb. per cycle in a 40-foot container divided into five growth rooms. The study determined the required number of containers for each production level based on various factors such as biological efficiency and cycle time. Results indicate that 1, 2, and 5 containers are needed for daily production of 50, 100, and 250 pounds of mushrooms, respectively, with inoculation schedules designed for nearly continuous production. The container-based approach maximizes limited urban space and supports sustainable food production, offering valuable insights for urban mushroom farmers. Further research could explore economic viability, environmental impact, and technology integration. Economic Analysis of Small-Scale Shipping Container Mushroom Farms: We've finalized a manuscript that conducts an economic analysis of small-scale shipping container mushroom farms, assessing their financial viability across different production capacities and mushroom varieties. Evaluating farm sizes of 55, 110, and 220 lb./day and four mushroom types under two financing scenarios, the study reveals significant economic challenges for small-scale operations, particularly with lower-value mushrooms like oysters. However, higher-value varieties like morels demonstrate profitability within 5 years, emphasizing the importance of variety selection for profitability. A balanced financing structure with a 50% bank loan and 50% equity generally yields higher net present values (NPVs) and shorter payback periods. The paper concludes that careful consideration of mushroom variety, production scale, and financing is crucial for optimizing small-scale mushroom farms. Further research into cost-saving measures and alternative financing options is recommended to enhance economic sustainability and capitalize on the potential of locally produced food. Cordyceps mushroom extracts as a biocontrol agent: Cordyceps militaris, an entomopathogenic mushroom from the Ascomycota group, has numerous applications in various industries due to its therapeutic and biocontrol properties. We evaluated C. militaris growth rate using microalgae (Spirulina and Chlorella) and macroalgae (Nori and Dulse) as substrate. Our studies showed that Spirulina as a substrate produced three times more dry weight than potato dextrose agarose media. We are in the process of testing various growth conditions to produce C. militaris mushrooms. Our goal is to achieve the highest yield of Cordyceps quickly.

This will help us to train high school, undergraduate, graduate students and small scale mushroom producers with hands-on experience with necessary training materials.
Impacts
What was accomplished under these goals?
Substrate processing system: We have successfully placed the order for the substrate processing system comprising of a steam generator, substrate milling machine, substrate mixer and densification unit. We are anticipating delivery of the system at the end summer 2023 that will be installed in one of the two 40 ft. shipping containers that will be commissioned at UH Sugar Land campus. Shipping container testbed: We were successful in receiving a UH infrastructure grant ($320,000) that will be used to build a test bed comprising of two shipping containers. This funding will help to establish a permanent testbed at UH campus. Several small and medium scale mushroom producers will receive hands-on training by participating in a certification program. We have finalized the design, identified the vendor and are in the process of receiving approval from UH facilities to place order and install the containers at UH Sugarland campus at the end of summer 2023. Using image processing to harvest mushrooms: Image processing and data analysis is an emerging technology used to assess the size and quality of mushrooms to determine the growth rate and measure yield. In this paper, we report different steps involved in collecting and processing image data in a large-scale commercial mushroom farm. We have demonstrated the technical feasibility of measuring the quantity and yield at different stages of mushroom cultivation which can be automated in the future. Developing this technology would allow mushroom producers to adjust the microclimate conditions to get better yield and coordinate harvesting schedules when quality is at its peak to maximize their profit. To extract relevant information about the mushrooms at a specific time, we followed the 8 steps for the 1960 time-series images captured during the experiment. 1) Image reading and cropping, 2) Grayscale conversion, 3) Image segmentation, 4) Contrast adjustment, 5) Canny edge detection, 6) Stitching sub-images, 7) Masking out noise and 8) Circular Hough transform algorithm. The above steps were applied on the images we collected for this project. This work has been published the 2023 IEEE International Wireless Communications & Mobile Computing Conference (IWCMC) and in IEEE conference proceeding in 2023. Steam conditioning of substrates and densification: Biotech capstone students completed a one semester project of substrate conditions using steam followed by densification using pelleting mill. The students identified the processing methods and successfully produced the biomass pellets. A master student has identified the protocols reported in the literature to evaluate the sterility of the densified biomass using an ATP measuring kit, culture plate and metagenomic analysis. Six different sterilization methods are currently being tested such as autoclaving, pasteurization, formalin, ozone, Bavistin and the newly developed method of steam conditioning followed by densification. We are in the process of checking the sterility of different sterilized substrates. Modeling small scale mushroom cultivation system: We have modeled a medium-scale mushroom farm with substrate storage and substrate processing. Unit operations such as milling, mixing, packing, sterilization, and mycelium inoculation to produce hundreds to a few thousand pounds of mushrooms per day using a 40-foot-long shipping container as a growth chamber. We used a computer-aided design (CAD) model in a software called SOLIDWORKS. We used substrate and processing condition information of oyster mushrooms growth conditions reported in the literature. We also evaluated the organization of different substrate beds packed in bottles, bags, and buckets to maximize the utilization of space and calculated the amount of oyster mushrooms that could be produced per container. This modeling study has helped us to determine the minimum footprint requirement to build a medium scale mushroom farm including the total number of required shipping containers. This will lay the foundation to estimate the cost of establishing such farm and return of investment based on the volume of mushroom produced. Similar modeling studies can be used to evaluate the cultivation of different varieties of mushrooms at different scales by varying the substrate combinations, packing methods, and growth conditions. We are in the process of summarizing this work and submitting two manuscripts. Micro and macroalgae to produce fungal mycelium and mushrooms: various types of micro- and macroalgae were evaluated as potential substrates for mycelium growth. The study aimed to explore the suitability of different algae species as a substrate for mushroom cultivation, focusing on the impact of algae on the growth and development of mycelium. Microalgae such as Chlorella and Spirulina were used, either alone or in combination, and were evaluated. Macroalgae, such as dulse, nori, wakame, kelp extract, Irish moss, and bladderwrack was evaluated. These species were selected for their high nutritional value and potential suitability as substrates for mushroom cultivation. Edible fungal mycelium requires a range of nutrients, including nitrogen, phosphorus, potassium, amino acids, and lipids to grow and develop properly. All algae are rich in these essential nutrients, as well as other micronutrients like vitamins and minerals that are important for mycelial growth. By incorporating these natural growth-promoting compounds, the development and growth of the mycelium can be enhanced up to four folds, ultimately resulting in denser and more robust fungal networks. This represents an innovative approach to mushroom cultivation that has the potential to improve the yield and quality of mushroom production. We have proved the concept using Calacybe indica (a tropical edible fungus) and are planning to explore several other commercially important fungi. We have submitted a patent application to UH intellectual property office based on these research findings.

Progress 06/01/21 to 05/31/22
Outputs
Target Audience:The target audence(s) are small scale mushroom producers. Our goal is develop methods of sustainably processing substrates and producing high value mushroomin shipping containers. Changes/Problems:Due to the long lead time in the current supply chain problem, we started identifying containers in the first year. Also, due to inflation the cost of materials and mushroom growth chambers has gone high. Also, there is significant deley in getting the growth chambers on time. What opportunities for training and professional development has the project provided?A group of four senior design undergraduate students from mechanical engineering program and two master students from computer engineering technology were mentored about developing environmental growth chambers prototype to produce mushrooms. They worked for two semesters to design a data driven growth chamber using different sensors and successfully demonstrated the operation of the prototype. Another group of four undergraduate students from biotechnology program and a Ph.D., student from Environmental Engineering received training to mushroom tissue culturing, producing mycelium, conditioning substrates, and producing mushrooms. A group of three BTEC capstone undergraduate student were trained to grow fungal mycelium to produce leather like material. One BTEC master student has received training on extracting fungal genome, carry out sequencing and annotation. One Mechanical Engineering Ph.D. student assists in the substrate system design and configuration. He also started working on mushroom product application exploration. How have the results been disseminated to communities of interest?We recently published two manuscripts in peer reviewed journals. One of the manuscripts is a review article that provide details about challenges in mushroom cultivation and discuss four major processing steps: (i) producing solid and liquid spawn, (ii) conventional and mechanized processing lignocellulosic biomass substrates to produce mushroom beds, (iii) maintaining growth conditions in climate-controlled rooms, and (iv) energy requirements and managements to produce mushrooms are also provided. This is an excellent resource for mushroom producers. We are developing a website to disseminate to mushroom growing communities. What do you plan to do during the next reporting period to accomplish the goals?We will complete the web-site with necessary education materials for mushroom producers. This platform will help us to connect with small scale mushroom growers in US. The machines will be installed, and the substrate processing conditions will be optimized to produce mushrooms in a shorter period and with good yield. We plan develop a computer model using Simio simulation software that will capture all the unit operations of mushroom cultivation and energy requirements. We will separately perform techno-economic analysis to calculate the cost of establishing a small scale mushroom cultivation using containers. We will connect with small scale mushroom growers and organize a two-day workshop at UH to demonstrate the substrate processing and mushroom cultivation.
Impacts
What was accomplished under these goals?
Developing data driven mushroom growth chamber: A senior design team comprising four students used SolidWorks software and designed the mushroom growth chamber prototype. The dimension of the mushroom growth chamber (17 x 20 x 15 inches). The chamber was made using square aluminum tubing and polycarbonate sheets. A master student from computer engineering install sensors such as temperature, humidity, and CO2 in the growth chamber. The sensors were interphase with Raspberry Pi controller and different environmental parameters were controlled using a software. The data was displayed on a small LCD screen. The function of the growth chamber was evaluated by maintaining the environmental condition at 85+2% humidity, 75+2oF, 1000+100 ppm CO2, and LED light for few days. This prototype will be used to train farmers about maintaining the right environmental conditions to produce good quality mushrooms with high yield. Substrate processing system: We first identified all the machineries (steam generator, substrate milling machine, substrate mixer and densification unit) that are needed for substrate processing to produce mushrooms by enquiring different vendors. We also designed a control panel to connect and operate all the machines. We used Solid works software to model all the machines and simulated the operation to monitor the flow in a shipping container. Then we placed the order to custom manufacture these machines and control panel to a vendor. There is some delay in shipping the machine due to supply chain problem. Once the machines arrive, they will be installed in a 40-foot insulated shipping container and will be used to condition the substrate for growing mushrooms in a growth chamber. Mushroom Cultivation: Four undergraduate BTEC student and Ph.D., students were trained to carry out tissue culturing two different fungus (Oyster and milky white) and produce fungal mycelium using grains. The pictures taken during the training were used in prepare a figure in the Applied Microbiology and Biotechnology review article 'Challenges and opportunities in producing high?quality edible mushrooms from lignocellulosic biomass in a small scale'. The students also received training to densify the biomass substrates and in the process of developing protocols to check their sterility. One master student from computer engineering technology developed an Imaging tool for commercial mushroom yield and quality estimation. A computer vision algorithm was developed that specializes in the identification of mushrooms in a growing room where mycelium growth and obstructions are common due to the ever-changing conditions inside a busy mushroom farm. The radii measurements obtained, has been used to count, measure area, and identify trends in the growth process. This new method will help measure mushroom production yields and profit margins by understanding what is happening in their growing rooms in real time.
