摘要：

The optimization of ethanol production by Pichia stipitis NRRL Y-7124 was analysed by ATP balance. Ethanol volumetric productivity was maximal (0.5-0.6 g/l h) only over a narrow range of oxygen transfer rates (3-5 mmol O2/l h). Trace element supplements increased ethanol volumetric productivity 20%. Biotin and thiamine did not significantly affect ethanol yield. Vitamins and trace elements were not synergistic. Organic nitrogen source from yeast extract was used for growth simultaneously to ammonia.
