Providencia alcalifaciens F90-2004

Providencia alcalifaciens F90-2004 is a Gram-negative, rod-shaped bacterium that serves as a component of animal intestinal microflora. It is classified as a chemoheterotroph, utilizing organic compounds as its energy source. This organism is a facultative anaerobe, meaning it can thrive in both aerobic and anaerobic environments, which is advantageous for survival within the diverse conditions of the intestinal tract. P. alcalifaciens F90-2004 possesses flagella, granting it mobility, which may assist in its colonization and interaction with the host's intestinal environment. The bacterium grows optimally at a temperature of 37°C, characteristic of mesophilic organisms, indicating its adaptation to the warm conditions typically found within the digestive system of animals. Notably, P. alcalifaciens F90-2004 is nonsporulating and contains a single replicon, signifying a streamlined genetic structure that may facilitate its rapid adaptation to changes in the intestinal milieu. The accession number for this strain is JACS00000000.1, which provides a reference for further genomic studies. From a biological and ecological perspective, the presence of P. alcalifaciens F90-2004 in animal intestines underscores its potential role in gut health and microbiome dynamics. Its ability to thrive in variable oxygen levels and utilize diverse organic substrates may contribute to nutrient cycling and microbial balance, reflecting the intricate relationships within the intestinal ecosystem.
