摘要:
In an alcohol fermentation process, oil derived from biomass is hydrolyzed into an extractant available for in situ removal of a product alcohol such as butanol from a fermentation broth. The glycerides in the oil can be catalytically (e.g., enzymatically) hydrolyzed into free fatty acids, which form a fermentation product extractant having a partition coefficient for a product alcohol greater than a partition coefficient of the oil of the biomass for the product alcohol. Oil derived from a feedstock of an alcohol fermentation process can be hydrolyzed by contacting the feedstock including the oil with one or more enzymes whereby at least a portion of the oil is hydrolyzed into free fatty acids forming a fermentation product extractant, or the oil can be separated from the feedstock prior to the feedstock being fed to a fermentation vessel, and the separated oil can be contacted with the enzymes to form the fermentation product extractant. The fermentation product extractant can be contacted with a fermentation broth for in situ removal of a product alcohol.
摘要:
The present invention relates to a process for preparing compositions of high concentrations of omega-3 fatty acids from krill. Furthermore, the invention relates to a composition comprising high concentrations of omega-3 fatty acids, and a lipid fraction from krill comprising high amounts of fatty acids with chain length C14 and C16.
摘要:
Provided herein are systems and methods for extracting lipids and/or producing biofuel from algae in marine and freshwater environments, wherein algae and bivalves are co-cultured in a system of enclosures comprising water that comprises recycled nutrients that are essential for algal growth. The system also include enclosures for culturing fishes which are used to harvest the algae.
摘要:
A process for recovering purified vegetable protein particularly soymeal protein by enzymatic treatment to dissolve the remanence employing a novel enzyme composition agent adapted to decompose a hitherto unreported pectic-like polysaccharide capable of binding to proteins. The process can recover protein from corn gluten, cotton seed meal, sunflower meal, rape meal etc.
