Abstract: A process for production of C5 and C6 sugar enriched syrups from lignocellulosic biomass and fermentation products therefrom is described. A lignocellulosic biomass is treated with a C1-C2 acid (e.g., acetic acid) with washing thereof with a C1-C2 acid miscible organic solvent, (e.g., ethyl acetate). A soluble hemicellulose and lignin enriched fraction is obtained separately from a cellulose pulp enriched fraction and lignin is removed from the soluble hemicellulose fraction. These fractions contain acylated (e.g., acetylated) cellulose and hemicellulose, which are deacylated by treatment with an alkali and/or with an acetyl esterase enzyme. The deacylated fractions are then digested with suitable cellulolytic and/or hemicellulolytic enzymes, preferably in the presence of non-ionic detergent to yield the C5 and C6 enriched syrups. Also described are method of fermentation of the syrups to make ethanol to at least 7% w/vol by separate hydrolysis and fermentation (SHF) or simultaneous hydrolysis and fermentation (SSF) methods.

Abstract: A scalable and sustainable process for production of renewable chemicals and biofuel from seaweed in its own juices or in seawater without desalination of the seaweeds is provided herein. The process as disclosed in the preset invention is an eco-friendly process for production of renewable chemicals and biofuel with an easy method of disposing of the waste streams. Further, the process as disclosed in the present invention is cost effective, suitable since transporting and storing the raw material obtained in the form of slurry of the seaweeds because of its lesser bulk is easy, easier handling due to its free flowing nature and its direct use for further processing to obtain renewable chemicals and/or biofuel.

Abstract: In the present disclosure, after a volatile organic acid is added as a catalyst to a slurry and the hydrolytic saccharification reaction of hemicellulose is performed, the volatile organic acid (including one added to the slurry and one produced as a by-product) contained in a C5 saccharified solution can be easily recovered by adding a small amount of sulfuric acid to the C5 saccharified solution and subjecting the C5 saccharified solution to air stripping treatment. The efficiency of hydrolytic saccharification of hemicellulose into C5 sugars using a volatile organic acid can also be continuously improved by adding the recovered volatile organic acid as a catalyst to another slurry of cellulosic biomass.
