  • Publication number: 20210269837
    Abstract: A biomass pretreatment method is provided to improve the bio-digestibility of lignocellulosic biomass. This pretreatment method densifies biomass with alkaline or acidic chemical(s) to obtain densified biomass containing chemicals. Pretreatment effects are realized during densification. The chemicals in densified biomass further react with biomass during biomass storage and transportation to improve the pretreatment effects. Further treatment (e.g. stream) can also be applied to the densified biomass to achieve better effects. As chemicals are mixed well with biomass during densification and the biomass density is greatly increased, further treatment is of high efficiency and high solid loading. This pretreatment method is simple and the densified biomass with chemicals is resistant to microbial contamination/degradation and thus facilitates storage and transportation.

  • Publication number: 20160265009
    Abstract: The present invention provides for the use of oleaginous yeast strains that are capable of converting lignocellulosic hydrolysates to lipids. More specifically, under specific molar carbon to nitrogen ratios of treated biomass hydrolysates, oleaginous yeasts are able to accumulate lipids that are suitable for the manufacture of biofuels and other products of interest. Additionally, some yeast species provided herein produce carotenoids when grown utilizing the disclosed methodologies.

  • Publication number: 20140227757
    Abstract: An integrated biological process for cellulosic bioproduct production is provided, which, in one embodiment, results in high ethanol productivity, enzyme recycling and reuse of yeast cells. The integrated process can be an integrated separate hydrolysis and fermentation (SHF) process or an integrated fast simultaneous saccharification and co-fermentation (FSSCF) process. The methods described herein can result in high bioproduct productivity through enzyme recycling and reuse of yeast cells.
