Post-consumer absorbent hygiene products can be economically converted to fermentable sugar intermediates, biofuels, and bio-based products
Biosynthetic bisabolene is a precursor to bisabolane – a potential renewable diesel fuel alternative.
Municipal solid waste (MSW) represents an attractive cellulosic resource for sustainable fuel production. However, its heterogeneity is the major barrier to efficient conversion to biofuels. MSW paper mix was generated and blended with corn stover (CS) in an ionic liquid process.
Technologies developed to generate bio-based products are based on single feedstock types. While this approach is applicable for corn stover in the MidWest, for states such as California, with abundant but diverse feedstocks, technologies should be developed to accommodate multiple feedstock input to a single biorefinery.
Ionic liquid (IL) pretreatment is receiving significant attention as a potential process that enables fractionation of lignocellulosic biomass and produces high yields of fermentable sugars suitable for the production of renewable fuels.
Rheology is the science of deformation and flow of matter, investigating the response of materials to applied stress or strain. Rheological properties describe flow characteristics and textural behavior of substances.
Bisabolane has been identified as a potential biosynthetic alternative to D2 diesel fuel. Researchers at JBEI have engineered S. Cerevisiae for the production of bisabolene, bisabolane’s immediate precursor, by the introduction of bisabolene synthase from A. Grandis.
Fed-batch fermentations involve controlled feeding of a growth limiting nutrient to a batch culture enabling higher cell densities. Some classic fed-batch strategies employ pH, OUR (oxygen uptake rate), DO (Dissolved oxygen) etc, as control parameters, based on their indirect correlations with growth.
Ionic liquid (IL) pretreatment has proven to be an effective method of biomass depolymerization for biofuel production. Understanding the physical and chemical properties of IL pretreated biomass at scale up level is essential to obtain better insights into challenges that may occur in large scale biorefineries.
