The overall goal of this project is to develop enabling technologies that utilize agriculture feedstocks and by-products for biobased materials and bioenergy, and to generate new knowledge that can be useful reference to both academia and industries in the field. In the past year, we continue improving wet adhesion of plant protein based adhesives for wood applications, and sorghum/bluestem biomass characterization and processes for efficient biofuel production. Plant proteins, such as soybean proteins contain a lot amino groups that cause water absorption leading to reduce wet adhesion of soy protein adhesives. Fatty acids was used to react with amino groups of soybean proteins and improve water resistance. We also continued conducting research on development of pretreatment methods for biological conversion processes with focus on 1) Ultrasonic Vibration-assisted Pelleting of biomass to increase biomass conversion efficiency; and 2) synthesization of silica-coated magnetic acid-functionalized nanoparticles for biomass pretreatment. In addition, KSU is working on pretreatment methods using organic green solvents and milder alkali concentration to ensure better quality sugars. The sugars will be converted to fatty acids, butanediol and lactic acid via engineered microbial fermentation.

How have the results been disseminated to communities of interest? The successful outcomes of the research will enable the effective use of biomass and processing methods to attain high conversion efficiencies in a sustainable way. Development of low-cost enzymes production methods via solid state fermentation will lower the cost of biofuels. In collaboration with Montana State University, University of Wyoming, and Industrial partners, Kansas State University lead a USDA-BRDI program to optimize camelina production system and develop byproducts from camelina meal to enhance the economic profitability of camelina biofuel/product system. Development of biobased adhesives could significantly impact a >$200 billion industry sector that currently relies on petroleum-based feedstock with its attendant environmental problems. Large markets exist for plywood, particleboard, transparent tapes, and coatings for construction, furniture, packaging and labeling, which represent huge demands for various adhesives. The newly developed biobased adhesives have a great potential to replace or partially replace petroleum-based adhesives for wood veneer, labeling, and other applications. Sustainable production of drop-in liquid biofuels and bioproducts from biomass feedstocks for transportation, aviation and chemical industry aligns closely with the USDA and DOE goals. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
Low-lignin content bmr-mutant forage sorghum grown at Riley and Doniphan counties, KS were compared with wild type high-lignin content forages to evaluate the effect of reduced lignin content in biomass on bioethanol production. Sorghum bagasse, wheat straw, switchgrass and miscanthus were used as wild type forages. Ground biomass samples were pretreated with 2% sodium hydroxide at 121 °C for 30 min followed by enzymatic hydrolysis using cellulase complex and β-glucosidase at high solid loading (20%, W/V), and the sugars released were fermented using Saccharomyces cerevisiae. Lignin content of all types of biomass was reduced to statistically equal levels (2-4%) after alkali pretreatment irrespective of their initial lignin content. However, saccharification efficiency of the pretreated biomass samples varied significantly from each other and showed a weak relationship between saccharification efficiency and total lignin content in raw and/or pretreated biomass. These results indicated that the reduced total lignin content in bmr-mutant crops does not necessarily benefit bioethanol production. Therefore, number of other factors, including lignin structure, crystallinity of cellulose and type of linkages in cellulose-hemicellulose-lignin complex must be further assessed to evaluate new crop lines for bioethanol production. Ethanol yield was more than 95% of the maximum possible theoretical yield based on released glucose in all types of biomass. Conservation Reserve Program (CRP) is a potential source of feedstock for bioenergy production. We investigated the effects of torrefaction conditions on the physicochemical properties of CRP biomass. Torrefaction upgrades biomass properties by increasing energy density, reducing MC, reducing particle size, increasing hydrophobicity, and increasing brittleness for easier grinding. Results suggest that the upgraded biomass is a hydrophobic, high-energy density, and low-moisture-content material. The study on biomass polymer composition showed how polymer components changed with processing conditions. The polysaccharides in biomass were degraded significantly at 300 °C, suggesting that processing conditions should be managed properly for sugar or energy recovery. Our economic analysis suggested that the processing cost for a torrefaction plant with an annual capacity of 100,000 tons of CRP biomass is $16.3 per ton of feedstock. Further analysis of the effects of torrefaction on the biomass supply chain suggested that processing could save pelletization and transportation costs. Three big bluestem ecotypes and the Kaw cultivar were harvested from four reciprocal garden planting locations and were used to study effects of ecotype and planting location on glucan content and glucan yield from enzymatic hydrolysis along the Great Plains precipitation gradient (~1200 to 400 mm mean annual precipitation). The populations varied widely in glucan content (31.8-36.5%), lignin content (14.4-18.0%), mass recovery (52.0-59.7%) and glucan recovery (79.0-87.50%) after acid treatment, enzymatic hydrolysis efficiency (84.6-88.9%), and glucan mass yield (20.8-29.3%). Ecotype and planting location as well as interaction of ecotype and location had significant effects on biomass composition and sugar yield. Planting location had a stronger influence than ecotype and interaction between location and ecotype. Total glucan content of the big bluestem (regardless of ecotype) and glucan mass yield increased as the Great Plains precipitation gradient increased from west to east. Annual precipitation, growing degree days, and potential evapotranspiration accounted for 94%, 93% and 93% of the variation in glucan content and yield, respectively. Di-hydroxylated soybean oil (DSO), a biobased polyol synthesized from epoxidized soybean oil (ESO) could be used to formulate resins for adhesives; however, current DSO synthesis requires harsh reaction conditions that significantly increase both cost and waste generation. In this paper, we investigate the kinetics of oxirane cleavage in ESO to DSO by water and elucidate the role of different process parameters in the reaction rate and optimization of reaction conditions. Our kinetic study showed that ESO oxirane cleavage was a first-order reaction and that the ESO oxirane cleavage rate was greatly influenced by tetrahydrofuran (THF)/ESO ratio, H2O/ESO ratio, catalyst content, and temperature. Optimized reaction parameters were THF/ESO of 0.5, H2O/ESO of 0.25, catalyst content of 1.5%, and reaction time of 3h at 25 °C. DSO with hydroxyl value of 242 mg KOH/g was obtained under these conditions. The resin tape exhibited peel adhesion strength of 3.6 N/inch, which is comparable to some commercial tapes measured under similar conditions. Di-hydroxylated soybean oil (DSO) polyols with three different hydroxyl values (OHV) of 160, 240, and 285 mg KOH/g were synthesized from epoxidized soybean oils (ESO) by oxirane cleavage with water catalyzed by perchloric acid. The DSOs were clear, viscous liquid at room temperature. The structure and physical properties of DSOs were characterized using titration methods, FTIR, gel permeation chromatography, rheometer, differential scanning calorimetry, and thermogravimetric analysis. The number average molecular weight of DSO160, DSO240, and DSO285 were 1412, 1781, and 1899 g/mol, respectively, indicating that oligomerization occurred during DSO synthesis, which was further confirmed by FTIR. All DSO polyols exhibited non-Newtonian, shear thinning behavior. DSOs with higher OHV were more viscous than those with lower OHV. These three DSOs were formulated into pressure-sensitive adhesives (PSA) by copolymerizing with ESO using UV curing. The peel adhesion strength of the PSAs was significantly affected by the OHV of DSO and DSO content. Maximal PSA adhesion strength of 4.6 N/inch was obtained with DSO285 and a DSO/ESO weight ratio of 0.75. Xylose is the dominating sugar after hydrolysis of hemicellulose in the biomass, but most microorganisms either cannot ferment xylose or have a hierarchical sugar utilization pattern in which glucose is consumed first. To overcome this barrier, Lactobacillus brevis ATCC 367 was selected to produce lactic acid. This strain possesses a relaxed carbon catabolite repression mechanism that can use glucose and xylose simultaneously; however, lactic acid yield was only 0.52 g/g from a mixture of glucose and xylose, and 5.1 g/L of acetic acid and 8.3 g/L of ethanol were also formed during production of lactic acid. The yield was significantly increased and ethanol production was significantly reduced if L. brevis was co-cultivated with Lactobacillus plantarum ATCC 21028. L. plantarum outcompeted L. brevis in glucose consumption, meaning that L. brevis was focused on converting xylose to lactic acid and the by-product, ethanol, was reduced due to less NADH generated in the fermentation system. Sequential co-fermentation of L. brevis and L. plantarum increased lactic acid yield to 0.80 g/g from poplar hydrolyzate and increased yield to 0.78 g lactic acid per g of biomass from alkali-treated corn stover with minimum by-product formation. Efficient utilization of both cellulose and hemicellulose components of the biomass will improve overall lactic acid production and enable an economical process to produce biodegradable plastics.
