Title: Bioconversion of plant biomass to ethanol. First bimonthly and quarterly report

Technical Report ·
DOI:https://doi.org/10.2172/5385154· OSTI ID:5385154

Research progress is reported in the development of an all-biological two-stage process for converting plant biomass into ethanol. The first stage will consist of a high-solids biomass pretreatment with a thermo-tolerant mold to remove sufficient lignin to make the cellulose available for saccharification. The second stage consists of a mixed culture fermentation and ethanol production using a thermo-tolerant anaerobic sporocytophaga to hydrolyze cellulose and a compatible thermo-tolerant bacillus to convert the soluble sugars formed during saccharification into ethanol. Initial studies on nutritional requirements of various thermophilic organisms and ethanol production are reported. (JGB)
