摘　　要：研究了国标法营养琼脂培养基(PCA)、R2A培养基,在不同的试验方法、培养温度、培养时间下,采用异养菌平板计数法测定管网水中菌落总数,试验结果表明,富营养培养基,较高温度和较短时间培养产生的菌落数,低于贫营养培养基在低温度和长时间培养条件下的菌落数,贫营养的R2A培养基具有更好的灵敏性。Study on the national standard method ofnutrient agar(PCA),R2A medium,in test method,different culture temperature,incubation time,the total number of colonies used in water Determination ofheterotrophic plate count method.The test results show that the nutrient rich medium,higher temperature and shorter time culture colonies produced,than that of the poor nutrient medium colonies under the condition of low temperature and long time,the sensitivity of oligotrophic R2A medium is better.
