Determination of revivable aerobic bacteria at 22°C and 36°C

The determination of revivable aerobic bacteria (RAB) at 22°C and 36°C makes it possible to assess the microbiological quality of liquid or solid samples, particularly in the water, food, environmental and surface sectors.

Culture at 22°C targets bacteria of environmental origin, while culture at 36°C allows the identification of mesophilic bacteria, potentially originating from human or animal contamination.

The method is based on inoculation in agar medium followed by incubation at controlled temperature for 44 to 72 hours.

The number of colonies is then expressed in CFU/mL or CFU/g. This analysis is essential for the control of process water, bottled water, plant extracts, cosmetics or industrial environments.

At YesWeLab , we collaborate with a rigorously selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the analytical techniques or methods required.
