【摘要】 大肠菌群(Coliforms)、耐热大肠菌群(thermotolerant coliforms)和埃希氏大肠杆菌(E.Coli)都是判断水体是否存在粪便污染的重要微生物指标。文中介绍了一种特定底物技术可在 24h之内同时检测大肠菌群和埃希氏大肠杆菌数量,如果提高培养温度至44.5±0.2℃,则可检测耐热大肠菌群数量。更多还原

【Abstract】 Coliforms,themotolerant coliforms and E.Coli are used as important indicator for determining faecal contamination in water. The defined substrate technology(DST) was introduced in this paper, which can be used to enumerate coliforms and E.Coli simultaneously. The DST was also used to enumerate thermotolerant coliforms by incubation at 44.5±0.2℃.更多还原
