阐述了利用选择性生长培养基和/或条件（包括最可能数（MPN）、存在/不存在（PA）和琼脂平板技术）制备土壤、沉积物、污泥[包括高颗粒含量液体（泥浆）]和生物固体以进行基于培养的细菌分析的方法。

Sets out a method for the preparation of soils, sediments, sludges [including high-particulate-content liquids (slurries)] and biosolids for culture-based bacterial analysis utilizing selective growth media and/or conditions, including most probable number (MPN), presence/absence (PA) and agar plating techniques.
