Proposed symbiotic consortium design. C. phytofermentans-yeast symbiotic consortium design based on cellulose hydrolysis to soluble cellodextrins which are utilized by yeast. Both C. phytofermentans and yeast produce ethanol from cellodextrins. Cellodextrins feedback inhibit cellulose hydrolysis, oxygen inhibits anaerobic bacterial growth while yeast oxygen consumption relieves inhibition.
