Kinetics analysis for dextranase of Pseudoalteromonas tetraodonis LP621 by liquid fermentation
摘要
Abstract
The kinetics for dextranase of marine bacteria Pseudoalteromonas tetraodonis LP621 by liquid fermentation was studied. The results showed that the dextranase production was partially associated with the growth of LP621. Based on the result of batch fermentation, the kinetic models for cell growth, dextranase formation, sugar consumption were set up using Logistic equation and Luedeking-Piret equation. The calculated results of models well matched the experimental data. The model equations could well reflect the dextranase fermentation process and kinetic characteristic.关键词
