The microbiology tests are very important to understand the microbial contamination in water, air and soil. The laboratory is well equipped to conduct various microbiological tests including bio-safety cabinet. The laboratory is also conducting bio-assay tests as per the Environment (Protection) Act, 1986 specification to understand the toxicity of effluents / river water, etc by involving live fish specimens.
