Citrobacter freundii MGH 56

Citrobacter freundii MGH 56 is a Gram-negative bacterium distinguished by its facultative anaerobic metabolism. This microbe can thrive in both aerobic and anaerobic environments, reflecting its versatility in utilizing different metabolic pathways depending on the availability of oxygen. C. freundii is part of the Enterobacteriaceae family and is typically found in a variety of habitats, including soil, water, and the intestinal tracts of humans and animals. As a facultative anaerobe, C. freundii MGH 56 can adapt its respiration processes to accommodate the presence or absence of oxygen, allowing it to occupy ecological niches where oxygen availability fluctuates. This adaptability may play a role in its survival and persistence in diverse environments, including those impacted by varying levels of organic matter and nutrient availability. While the specific pathogenic potential of C. freundii MGH 56 is not detailed here, the broader genus has been associated with opportunistic infections in humans. Its metabolic flexibility may enable it to exploit various substrates in its environment, contributing to its ecological success. Understanding the traits of C. freundii MGH 56 provides insights into the adaptability of Gram-negative bacteria in changing ecological contexts, reflecting the complex interactions that shape microbial communities.
