在实验室研究中，通过化学凝聚去除酵母菌和耐酸菌与目前公认的指示菌群总大肠菌群进行了比较。这些研究表明，与大肠菌群相比，混凝和过滤对酵母菌和抗酸菌的去除程度不高，而且由于酵母菌和抗酸菌比大肠菌群更耐氯，因此酵母菌和抗酸菌可能是比传统指标更有效的水消毒效率指标。包括12个参考文献、表格和图表。

The removal of yeasts and acid-fast organisms by chemical coagulation was compared in laboratory studies with that of the currently accepted group of indicator organisms, total coliforms. These studies indicate that coagulation and filtration do not remove yeasts and acid-fast organisms to a greater extent than coliform organisms, and since yeast and acid-fast organisms are more resistant to chlorine than coliforms, yeasts and acid-fast organisms may be more valid indicators of the efficiency of water disinfection than the traditional indicators.
