Description | To produce D-lactic acid and ε-Poly-L-lysine from glucose derived from sugar cane bagasse, the production of fermentable sugars from un-utilized sugarcane bagasse was studied by hydrothermal method, steam explosion and further saccharification of the pretreated solid residues. The maximum values, i.e. 76% and 97%, of glucose in the polysaccharide of steam-exploded material and water extracted residue after steam-explosion were obtained at 20 atm steaming pressure, respectively. The high yields of D-lactic acid, i.e. 81% and 87%, were attained from glucose derived from extracted residue with water after steam-explosion and extracted residue with water and alcohol after steam explosion, respectively. In the case of production of ε-Poly-L-lysine, 4.4% of ε-Poly-L-lysine in the total amount of glucose was achieved using steam-exploded bagasse hydrolysate treated with ion-exchange resin as carbon sources.
