Twin-Screw Extrusion Processing Of Plant-Based Blends Using Graded Levels Of High Protein Fermented Soybean Meal (Fsbm), Parisa Fallahi, Kurt A. Rosentrater, K. Muthukumarappan Jan 2019

Twin-Screw Extrusion Processing Of Plant-Based Blends Using Graded Levels Of High Protein Fermented Soybean Meal (Fsbm), Parisa Fallahi, Kurt A. Rosentrater, K. Muthukumarappan

Agricultural and Biosystems Engineering Publications

Fast-paced growth in global aquaculture has elevated concerns about the high costs of fish farming production and potential water pollution. Thus, finding eco-friendly and more sustainable alternative protein sources for fish diets is of vital importance to the industry. A twin-screw extrusion processing study was performed using three ingredient blends formulated with graded levels of high protein fermented soybean meal (FSBM) (0, 80% and 100% db fishmeal replacement) along with calculated amounts of other ingredients to meet the rainbow trout diets’ requirements. Increasing the FSBM content from 0% to 100% resulted in a substantial increase in brightness, greenness, and yellowness ...

Ethanol (CH3CH2OH) is one of the most important individual organic compounds readily available all over the world. It has been described as one of the most versatile of compounds, being widely used as a solvent, a germicide, a beverage, an antifreeze, a fuel, and fuel additive, additive to paints, coatings, automotive care products and adhesives, a fragrance, a lubricant, and as an intermediate for the synthesis and production of other organic compounds. Ethanol is mainly produced through yeast fermentation of sugars from seeds, sugar cane or beets and concentrated through subsequent distillation. Its main use is as a liquid fuel ...


Ffa Generation During Dry-Grind Corn Ethanol Fermentation, Brett Brothers Jan 2018

Ffa Generation During Dry-Grind Corn Ethanol Fermentation, Brett Brothers

Graduate Theses and Dissertations

The fermentation of corn into ethanol is a major usage of the American-grown corn crop. During the process of corn to ethanol, corn lipid class composition changes. The formation of free fatty acid (FFA) from triacylglycerol is commonly observed. Increased free fatty acid fermentation byproducts result in troublesome processing to remove excess FFA. The objective of this work was to determine where in the process of corn to ethanol FFA is generated using both industrial and laboratory-scale approaches. Specific commercial steps and conditions in the process of corn to ethanol were tested to determine their role in the generation of ...


Production Of Fatty-Acyl-Glutamate Biosurfactant By Bacillus Subtilis On Soybean Co-Products, Mustafa E. Marti, William J. Colonna, Gabriel Reznik, Michelle Pynn, Kevin Jarrell, Buddhi P. Lamsal, Charles E. Glatz Mar 2015

Chemical and Biological Engineering Publications

Fatty-acyl-glutamate (FA-Glu), a surfactin variant has been successfully produced using a genetically modified strain of Bacillus subtilis grown on glucose. However, yields with soybean hulls (SBH) replacing glucose were lower. This work was undertaken to reduce the yield loss when using SBH as the carbon source and to evaluate two other soy by-products, namely fiber and skim from aqueous oil extraction as alternative carbon and nitrogen sources.

Fermentation of soybean hulls, fibers and skim at various concentrations produced lower FA-Glu titers compared to S-7 medium. Neither increasing their amount nor supplementing with glucose increased the FA-Glu titer, suggesting the presence ...


Life Cycle Assessment (Lca) And Techno Economic Analysis (Tea) Of Algal Biomass And Biodiesel Production From Pyrolytic Substrate, Xuefei Zhao, Zhiyou Wen, Kurt A. Rosentrater Jul 2014

Life Cycle Assessment (Lca) And Techno Economic Analysis (Tea) Of Algal Biomass And Biodiesel Production From Pyrolytic Substrate, Xuefei Zhao, Zhiyou Wen, Kurt A. Rosentrater

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Hybrid processing of cellulosic biomass, composed of thermochemical-based pyrolysis of biomass into fermentative substrates followed by biochemical-based algal fermentation into lipid-rich biomass was developed. The hybrid process has proven an effective way for producing biofuel from lignocellulosic biomass. In this work, life cycle assessment and techno economic analysis were performed for algal fermentation of the acetic-acid rich stage fraction of bio-oil under different scales and fermentation conditions. These results will provide guidance for choosing optimal algal fermentation parameters. Moreover, with more biodiesel produced, increased environmental and economic benefits per gallon of biodiesel can be expected.
