Dynamics of Enzymatic Hydrolysis Solution from Soybean Straw Fermentation the Making L-lactic acid by Immobile Lactobacillus
Soybean straw is biodegradable cellulose resource, but it has not been utilized for a long time. 2/3 straws was combusted and producing resources waste and air pollution. In this study, taking soybean straw as raw material, dynamics that enzymatic hydrolysis solution from soybean straw fermentation the making L-lactic acid by immobile lactobacillus was studied. The dynamics equation of the immobile lactobacillus growth and L-lactic acid fermentation was conducted separately according to Monod equation and Gaden equation. Dynamic model and parameter of L-lactic acid fermentation was gained. The equation provided theories foundation for the industrialization of soybean straw or other cellulose resources recycling. Meantime, the poly lactic acid through L-lactic acid polymerization is a kind of biodegradable plastic, utilizing it instead of present non-biodegradable plastic can reduce pollution for environment.
