摘要
探讨了采用测试瓶法检测景观水中细菌总数的可行性和操作方法,细菌培养条件为37℃下恒温1～2 d。平皿计数法和测试瓶法对照试验的数据显示,二者相对误差在10%左右,在景观水的细菌总数测定中可以用测试瓶法代替或者部分代替平皿计数法。测试瓶法可在水体现场进行操作,无需采样保存,检测及时,且能够缩短检测时间、简化操作条件和步骤,节省资源和人工工作量。
The feasibility and operational approach of test-bottle method in determination of total bacterial count in landscape water are discussed. The bacteria are cultured for 1 to 2 d at 37 ℃. The comparison test results of plate count method and test-bottle method show that the relative error between the two methods is about 10%. So the test-bottle method can either replace plate count method or a part of it in determination of total bacterial count in landscape water. This method can be used on site without sample preservation, and it has characteristics of timely determination, short time, simple operational conditions, saving resources and workload.
