| Description | Enterobacteriaceae bacterium 9_2_54FAA is a gram-negative, rod-shaped bacterium that thrives at mesophilic temperatures, categorizing it as a facultative anaerobe and a chemoheterotroph. Members of the Enterobacteriaceae family are predominantly found in the intestines of warm-blooded organisms, but this particular strain can also inhabit various other body sites across different species, including the digestive tract, respiratory system, and skin. As a gram-negative bacterium, Enterobacteriaceae bacterium 9_2_54FAA possesses a thin peptidoglycan layer surrounded by an outer membrane, which contains lipopolysaccharides. This structural feature not only contributes to its staining properties but also offers robust protection against environmental stressors and antibiotics. The rod shape allows for motility, and in some cases, it may possess flagella, enabling it to navigate through different environments. Its mesophilic temperature preference indicates that it thrives best at moderate temperatures, typically around 30°C to 37°C, which aligns with the body temperature of its host organisms. Being a facultative anaerobe, it can utilize oxygen for aerobic respiration when available but can also switch to fermentation or anaerobic respiration in its absence, adapting flexibly to varying oxygen conditions. As a chemoheterotroph, Enterobacteriaceae bacterium 9_2_54FAA obtains its energy by metabolizing organic compounds from its surroundings, which is a common trait among gut microbiota. This microbe plays a crucial role in nutrient cycling and maintaining gut health, exhibiting competitive dynamics with other microbiota species. Moreover, studies indicate that Enterobacteriaceae bacterium 9_2_54FAA may hold potential in various biotechnological applications, such as bioremediation and the production of biofuels, underscoring its significance beyond traditional ecological roles. |
