标准范围

该程序适用于所有类型的水，但当大量颗粒材料易于被膜截留时除外。该原理包括几个步骤，从加热以破坏营养细菌的选择，到通过具有合适孔径（0.2μm）的膜过滤器过滤水样以将孢子保留在其中或其上。将过滤器放置在选择性培养基上，然后孵育和计数黑色菌落。

The procedure is applicable to all types of water, except when a large amount of particulate material is liable to be retained by the membrane. The principle covers several steps from selection by applying heat to destroy vegetative bacteria to filtration of the water sample through a membrane filter having a suitable pore size (0,2 μm) to retain the spores in or on it. The filter is placed on a selective culture medium, followed by incubation and counting of black colonies.
