چکیده انگلیسی
The synthetic characteristics of the extracellular polysaccharide (EPS) of Ganoderma lucidum in batch fermentation were studied. The result showed that the production of EPS was partially growth-associated. The cell dry weight (CDW) and EPS reached 15.56 g·Lâ1 and 3.02 g·Lâ1, respectively. The yield of EPS to cell dry weight (Yp/x) was 0.19. On the basis of the test results of batch fermentation, a kinetic model was proposed by using the Logistic equation for cell growth, the Luedeking-Piret equation for EPS production, and the Luedeking-piret-like equation for the consumption of glucose as substrate. The calculated results using these models were satisfactorily compared with the experimental data under various concentrations of glucose, and the average of relative errors was found to be not more than 5%. The kinetic model had practical guidance interesting in producing PES by Ganoderma lucidum.
