Acetobacter pasteurianus NBRC 3188

Acetobacter pasteurianus NBRC 3188 is a Gram-negative, nonsporulating bacterium that functions as a chemoheterotroph, thriving optimally at a temperature of 30°C. This species is primarily isolated from dairy environments, indicating its adaptation to habitats rich in organic compounds, such as those found in milk and dairy products. As an aerobic organism, A. pasteurianus requires oxygen for its metabolic processes, a characteristic that facilitates its growth in oxygen-rich environments. Its ability to utilize various organic substrates allows it to play a significant role in the fermentation processes associated with dairy products, potentially influencing the flavor and quality of fermented dairy items. The ecological relevance of A. pasteurianus extends to its contributions to the microbial community in dairy environments, where it may interact with other microorganisms, thereby affecting fermentation dynamics and product characteristics. The bacterium's metabolic capabilities suggest that it could be harnessed for biotechnological applications in the dairy industry, particularly in the production of vinegar and other fermented products. Understanding the specific interactions and roles of A. pasteurianus within its habitat could provide insights into optimizing fermentation processes and enhancing product quality in dairy production.
