Acetobacter pasteurianus NBRC 3299

Acetobacter pasteurianus NBRC 3299 is a Gram-negative, nonsporulating bacterium that functions as a chemoheterotroph, utilizing organic compounds as its energy source. This microbe thrives in aerobic conditions, with an optimal growth temperature of 30.0°C. Isolated from dairy environments, A. pasteurianus plays a significant role in the fermentation processes associated with dairy products, particularly in the production of vinegar and other fermented foods. As an aerobic organism, A. pasteurianus requires oxygen for its metabolic processes, which is consistent with its habitat in dairy environments where oxygen is readily available. Its nonsporulating nature indicates that it does not form spores, which may influence its survival strategies and ecological interactions within its niche. The bacterium's ability to thrive at 30.0°C suggests adaptation to the moderate temperatures commonly found in dairy processing and storage conditions. Insights into the metabolic capabilities of A. pasteurianus could provide valuable information for enhancing fermentation processes and improving product quality in dairy industries. Its role in converting alcohol to acetic acid highlights its potential utility in biotechnological applications, particularly in the production of vinegar and other acidic products, thus emphasizing its importance in both ecological and commercial contexts within the dairy sector.
