Assay of viable aerobic bacteria at 22°C and 36°C

The assay of viable aerobic bacteria (BAR) at 22 °C and 36 °C allows the microbiological quality of liquid or solid samples to be assessed, particularly in the water, food, environment and surface sectors.

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

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 carefully 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 required analytical techniques or methods.
If you have any particular requirements, please do not hesitate to specify them in your request: our scientific team will do everything possible to respond accurately and promptly.
Since 2020, numerous manufacturers, distributors, and engineering firms have entrusted us with the management of their analyses, sending us their samples through our digital platform.
