Abstract:
A heat shock treatment was studied in glycerol fermentation of osmotolerant yeast Candida krusei. The experiment results showed that the optimal temperature and duration time for heat shock is 45℃ and 30 min respectively,and the optimal start time of the treatment is at the mid term in exponential growth stage. With such treatment, glycerol yield was enhanced greatly,while no signficant effects on both cell growth and glucose consumption were observed.
