摘要：pH values and microbial colony forming unit (CFU) of JP 11 purified waters (8 samples) were studied. pH values of 8 samples tested were between 5.64 to 5.98. No bacteria were detected from 2 test samples for 3 months. A few bacteria were detected in another samples at immediately after preparation, and after 1 month microbial CFU in 3 sample increased remarkedly. The microbial CFU in these samples were 6.7×10³-1.2×10⁵ CFU/ml. Most bacteria isolated were gram negative rod after 1-3 month, and these were identified as Shigella sp. by using api 20NE system. Slight correlation between the increase of microbial CFU and the contents of total organic carbon (TOC) were found.
