Providencia alcalifaciens F90-2004

Providencia alcalifaciens F90-2004 is a Gram-negative, nonsporulating rod-shaped bacterium that thrives as a chemoheterotroph, utilizing organic compounds for energy. This species is facultatively anaerobic, enabling it to adapt to varying oxygen levels within its habitat, which is primarily the intestinal microflora of animals. The optimal growth temperature for P. alcalifaciens F90-2004 is around 37.0°C, aligning with the physiological conditions found in the intestines of warm-blooded hosts. The presence of P. alcalifaciens in the gut microbiome suggests a potential role in nutrient processing and microbial interactions within the intestinal ecosystem. This bacterium’s ability to survive and function efficiently in the complex environment of the animal intestine highlights its adaptability and suggests that it may participate in competitive dynamics with other gut microbes. Further studies could illuminate its specific contributions to gut health and its interactions with the host's immune system, providing insights into the broader implications of gut microbiota composition on host physiology.
