STUDIES ON THE BATCH-FERMENTENT AND THE FERMENTENT KINETICS OF YEAST-L STARKEYI HL
|
Abstract:
Based on the flask culture conditions, the batch and fed batch of fermentor cultures were performed in a small fermentor. The kinetics of growth and lipid producing were also studied, and the result indicated that using a fed-batch couldn't only prolong the period of lipid synthesis but also markedly retard the fast decreasing of specific lipid productivity after the time of sugar exhaustion. besides these, the cell density and the amount of lipid could also be increased. A content of 11.og/L lipid and 19.4g/L dry biomass were determined at 120h and the cell contained 56.5% lipid by using a fed-batch at the later period of fermentaion.
