Ways to reduce the labor intensiveness of applying the method of optical estimation of microbial cell concentration in suspension.

The labor intensity (in hours) of the optical method of microbial cell counting in suspension compared to the method of microbial cell counting using a Goryaev chamber is evaluated. The relevance of assessing the production labor intensity of microbial cell counting methods in suspension is related to the need to use them in many studies. Often the commonly used methods are too labour-intensive, time-consuming, or require expensive equipment.
