Quality of any product depends on the type of packaging, shelf life, presence and nature of micro-organisms contained in a particular product. Under favorable conditions microorganisms present proliferate and result in loss of product quality. Microbiological monitoring is an essential part of quality control where Lucid labs helps in product testing and evaluation
