Klebsiella pneumoniae, Enterobacter aerogenes, Agrobacterium tumefaciens, Streptococcus faecalis, Micrococcus flavus, Bacillus subtilis, and Pseudomonas strains L2 and 719 were tested for the ability to grow and maintain viability in drinking water. Microcosms were employed in the study to monitor growth and survival by plate counts, acridine orange direct counts (AODC), and direct viable counts (DVC). Plate counts dropped below the detection limit within 7 days for all strains except those of Bacillus and Pseudomonas. In all cases, the AODC did not change. The DVC also did not change except that the DVC, on average, were ca. 10-fold lower than the AODC.
对肺炎克雷伯菌、产气肠杆菌、根癌土壤杆菌、粪肠球菌、微黄微球菌、枯草芽孢杆菌以及假单胞菌菌株L2和719进行了在饮用水中生长及维持生存能力的测试。本研究采用微型生态系统通过平板计数、吖啶橙直接计数（AODC）和直接活菌计数（DVC）来监测生长和存活情况。除芽孢杆菌和假单胞菌外，所有菌株的平板计数在7天内降至检测限以下。在所有情况下，AODC均未改变。DVC也未改变，只是平均而言，DVC比AODC低约10倍。
