摘要: 用微量热法研究细菌生长代谢过程已有大量报道[1-4],可求出细菌生长的速率常数,激活能[5]、有关的热力学参数[6]以及细菌的临界生长温度[7],但药物对细菌最佳生长温度的影响等尚未见报道.

Abstract: By using microcalorimetric method, the thermogenesis power curves of aerobacter aerogenes growth at different temperature and under the action of different drugs were determined. From the thermogenesis power curves. the growth rate constants k of aerobacter aerogenes were calculated as: lnP1= lnP0+k ·t. From the equation k =A(T-a)en(T-a),the optimum growth temperature Tm= (310.21?0.94) K was obtained. Tm is a very significant constant of bacterial growth.

Key words: optimum temperature of bacterial growth, schiff base, thermochemistry, microcalorimetric method
