Serratia marcescens str. B3R3

Serratia marcescens str. B3R3 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, thriving optimally at 37.0°C. As a chemoheterotroph, this strain utilizes organic compounds as its energy source, allowing it to inhabit a variety of environments. The nonsporulating nature of S. marcescens str. B3R3 indicates that it relies on other survival strategies rather than endospore formation to withstand unfavorable conditions. This microbe is part of a genus known for its adaptability and diverse ecological niches, often found in soil, water, and as part of the microbiota in various organisms. The ability to grow in both aerobic and anaerobic conditions enhances its survival and proliferation across different habitats. Its metabolic versatility enables S. marcescens str. B3R3 to exploit a range of organic substrates, which may provide insights into its role in nutrient cycling within its ecosystems. Understanding the traits of S. marcescens str. B3R3 emphasizes the importance of studying its ecological interactions, particularly in environments where organic matter is abundant. This adaptability suggests that the bacterium may play a significant role in the decomposition processes and nutrient dynamics of its habitats, contributing to the overall microbial community structure and function.
