Morganella morganii subsp. morganii str. ATCC 25830

Morganella morganii subsp. morganii str. ATCC 25830 is a Gram-negative, facultative anaerobic bacterium. This organism is characterized by its ability to thrive in both aerobic and anaerobic environments, which suggests a versatile metabolic capacity that may contribute to its adaptability in diverse ecological niches. As a member of the Enterobacteriaceae family, M. morganii subsp. morganii is typically rod-shaped, exhibiting the morphological and physiological traits common to this group of bacteria. The facultative anaerobic nature of M. morganii subsp. morganii indicates that it can utilize oxygen for respiration when available but can also switch to fermentation or anaerobic respiration in the absence of oxygen. This metabolic flexibility may allow it to colonize various environments, including those with fluctuating oxygen levels, such as the gastrointestinal tracts of animals or in decaying organic matter where oxygen is limited. Due to its Gram-negative cell wall structure, M. morganii subsp. morganii possesses an outer membrane that can confer resistance to certain antibiotics, a trait that is often observed in Gram-negative bacteria. This characteristic, combined with its facultative anaerobic capabilities, could play a role in its survival and persistence in competitive environments where it may encounter antimicrobial agents. Overall, the adaptability of Morganella morganii subsp. morganii str. ATCC 25830 to varying oxygen levels may provide insights into its ecological role in nutrient cycling and its interactions with other microbial communities in various habitats.
