Now most water utilities and drinking water guidelines still rely solely on time-requiring heterotrophic plate counts(HPC)under the condition for the 24h and 37℃constant temperature culture.
本论文作为对ATP生物发光法的实际应用研究,通过测定实验室已知菌种不同OD_(600)值,并对相应的OD_(600)值同时进行平板计数和ATP生物发光强度的测定,得到两种方法的相关方程,继而测定细菌数较多的水样以及细菌含量较少的市售矿泉水;提高ATP生物发光法检测微生物数量的极限值,从而使得该方法在方便快速的同时,达到卫生学检验的要求。
