. Deal with the petri dishes, mix the sample with the agar by tilting or rotating the dishes, and permit the contents to solidify at space temperature. Invert the petri dishes, and incubate for forty eight to seventy two hours.

The Microbial limit test (MLT) is carried out to assess the amount of and which of specific practical microorganisms are existing in non-sterile pharmaceutical, Health care or cosmetics producing samples that range from Uncooked components to concluded products.

v  Categorical the result as Colony Forming Device (cfu) per gm/ml divided by quantity taken by       multiplying ordinary number of cfu/plate with dilution aspect. If no colonies are noticed Categorical the result as number of colonies under dilution factor. 

Time of sampling ought to be at the conclusion of processing and packaging. The sample must be from homogenous bulk. Aseptic managing and technique are needed.
