biological activity of saccharomycopsis lipolytica 70551 for citric acid production in a continuous culture

ABSTRACT

The biological activity of Saccharomycopsis lipolytica 70561, was studied in a chemostate culture at a different dilution rates. The specific rate of sugar uptake and growth were increased with increase of dilution rate reaching its maximum at a dilution rate of 0.02 h-I. The optimal production rate of citric acid was detected at a dilution rate of 0.0114 h-I. Effects of nitrogen concentration on growth, specific production rate, yield factor and productivity of citric acid were also studied
