ADVANCED METHODS FOR SUGAR PRODUCTION FROM LIGNOCELLULOSIC BIOMASS AND FERMENTING SUGARS TO MICROBIAL LIPIDS

摘要

Methods for facilitating sugar release from lignocellulosic biomass and for utilizing the sugars for microbial lipid (e.g. biofuel) production are provided. The methods involve pretreating lignocellulosic biomass using various oxidizing agents (ozone, peroxone, etc.) at a temperature not higher than 50°C and pressure no higher than 1.5 atm to render the biomass more accessible to enzymatic hydrolytic degradation into sugars and utilizing soluble sugars for fermenting oleaginous microorganism to produce microbial lipids.
