From the thermogenesis curves, we established the growth thermokinetic equation:dp/dt = km Pn,the order of growth metabolism n=0, and calculated the mean specific rate constant of multiplication μ. It is a new kind of bacterial growth,it was compared with exponential growth.展开更多

Some characteristic values have been obtained from these curves in different thermogenesising stages of the germination of rice and tree seeds. These parameters can be used in comparison of character and activity for different seeds,moreover the effects of different strain.germinating shape and temperature on the power-time curves of the germination of seeds have been discussed.展开更多

The results show that porphyrin-chsterol esters can powerfully inhibit their metabolism, the inhibitory sequence is Ⅱ >I >Ⅲ,but the inhibitory way of each ester is different.展开更多
