A brief overview of the applicability of FISH methods in environmental engineering

Fluorescent in situ hybridization (FISH) is a commonly used method for the detection of microorganisms in heterogeneous environment. It is primarily used for quantitative analysis of microorganisms. FISH gives possibilities of evaluating activities of some bacteria and their physiological state in the environment. In the recent years, ftuorescent in situ hybridization has been improved and adapted for the research on environmental samples.
