| 英文摘要 | the power-time curves of growth of three strains of petroleum bacteria at different nacl concentrations at 40.0 and 50.0 degreesc have been determined by using a 2277 thermometric thermal activity analyser. an equation of a power-time curve, ln[alphap(k)/p(t) - 1] = ln[(alphak - n-0)/n-0] - alphakt, was established based on the generalized logistic equation, where p(t) is the thermal power at time t, k the carrying capacity, p-k = p0k, p-0 the thermal power of one cell, n-0 the bacterial population at time zero, alpha = (k - d)/k. the method of four observed points with the same time interval was used to calculate the value of p-k. the growth rate constant k and the death rate constant d were calculated. the nacl concentration of optimum growth rate of petroleum bacteria at 40.0 and 50.0 degreesc, respectively, have been obtained according to the curves k - d versus nacl concentration, which are 0.26, 0.54 and 0.57 mol l(-1) for b-1, b-2 and b-3, respectively, at 50.0 degreesc, 0.26, 0.55 and 0.56 mol l(-1) for b-1, b-2 and b-3, respectively, at 40.0 degreesc. the results indicated that the effect of temperature on nacl concentration of optimum growth rate was small.
