Acetobacter pasteurianus 386B

Acetobacter pasteurianus 386B is a Gram-negative bacterium primarily isolated from dairy environments. As a chemoheterotroph, it derives its energy from organic compounds, reflecting its adaptation to nutrient-rich habitats such as dairy products. This organism is characterized by its bacilli shape and is non-motile, lacking flagella despite the presence of flagella genes. A. pasteurianus 386B is an aerobic bacterium, requiring oxygen for growth, and thrives optimally at 30°C, which places it within the mesophilic temperature range. The bacterium is nonsporulating, indicating it does not form spores as a survival strategy under adverse conditions. A notable genetic feature of A. pasteurianus 386B is the presence of eight replicons, which may contribute to its adaptability and metabolic versatility. In terms of ecological interactions, A. pasteurianus 386B exhibits a symbiotic relationship, suggesting that it may play a role in the microbial community of dairy environments. This symbiosis could involve interactions with other microorganisms, potentially influencing fermentation processes or contributing to the preservation of dairy products. Overall, the traits of A. pasteurianus 386B highlight its specialized adaptation to dairy habitats and its role in aerobic environments, which may be significant in understanding its contributions to dairy fermentation and preservation processes.
