  • Process for liquid/solid separation of lignocellulosic biomass hydrolysate fermentation broth
    Patent number: 8906235
    Abstract: When lignocellulosic biomass hydrolysate is included in fermentation medium, the broth resulting from biocatalyst production is complex with low filterability. A heat treatment was found to increase filterability, allowing efficient separation of a liquid fraction from a solid fraction, which is further processed for water recycle and syrup production.
    Type: Grant
