Acetobacter pasteurianus subsp. pasteurianus strain SRCM101342

Acetobacter pasteurianus subsp. pasteurianus strain SRCM101342 is a Gram-negative, nonsporulating bacterium that thrives as a chemoheterotroph, primarily utilizing organic compounds for energy. This strain is optimally active at a temperature of 30.0°C and exhibits aerobic respiration, indicating a requirement for oxygen in its metabolic processes. Isolated from dairy environments, A. pasteurianus subsp. pasteurianus plays a significant role in the fermentation processes of dairy products, contributing to the production of acetic acid and other metabolites that influence flavor and preservation. The strain's ability to grow in aerobic conditions suggests that it may be particularly well-suited for environments rich in organic substrates, such as those found in the dairy industry, where oxygen availability is often sufficient. The nonsporulating nature of this strain indicates a reliance on favorable conditions for survival and reproduction, which may limit its resilience in harsh environments compared to sporulating bacteria. The ecological role of A. pasteurianus subsp. pasteurianus in dairy fermentation highlights its potential utility in biotechnological applications, such as the enhancement of food preservation and flavor development in fermented dairy products. Further studies could elucidate the specific metabolic pathways utilized by this strain, contributing to the understanding of its functional capabilities within the microbiome of dairy environments.
