FIELD: chemistry.
SUBSTANCE: invention relates to biochemistry. Disclosed is a method of determining maximum concentration of living bacteria. A suspension of bacteria with turbidity standard of 5 units is brought to concentration of 500000 mc per 1 ml. Electrical resistance of the suspension is then determined in a direct current field with maximum voltage across open ends of electrodes of 2.8 V. Maximum resistance in the range of 900-1500 kOhm indicates maximum concentration of living bacteria in suspensions of different types of microorganisms.
EFFECT: method provides quality estimation of concentration of living bacteria, which is sufficient for further identification of said bacteria, and cuts analysis time.
