摘要

Saline sodic soils have been used for production of biomass using salt tolerant perennial grasses, namely Leptochloa fusca (kallar grass) followed by lesser tolerant plant, namely, Panicum maximum to provide biomass throughout the year for production of single cell protein, celllases hemicellulases and ethanol. The concentrated enzyme titers obtained after growth of C. biazotea on kallar grass using sodium nitrate as nitrogen source could saccharify alkali-treated wheat straw, bagasse, carboxy methyl cellulose and alpha-cellulose to monomeric sugars (? 88% theoretical yield) but not kallar grass straw. In simultaneous saccharification and fermentation studies, 94 and 90 % theoretical yield of ethanol from wheat straw and bagasse from 10% carbohydrates in both substrates were achieved compared with alpha-cellulose, which supported 96 % theoretical yield of ethanol.
