Yersinia bercovieri

Yersinia bercovieri is a Gram-negative, rod-shaped bacterium characterized by its occurrence as single cells and its inability to form spores. This microbe is classified as a facultative anaerobe, indicating its capability to grow in both aerobic and anaerobic environments. Y. bercovieri demonstrates heterotrophic metabolism, relying on organic compounds as its energy source, which suggests a versatile adaptability to various nutrient sources in its habitat. The optimal growth temperature for Y. bercovieri is 28.0 °C, which positions it within a mesophilic range, conducive to its survival in diverse environments. The bacterium's ability to thrive in multiple habitats underscores its ecological versatility, likely enabling it to inhabit a variety of niches where organic matter is available. Y. bercovieri's facultative anaerobic nature may contribute to its resilience in fluctuating environmental conditions, allowing it to exploit transiently available oxygen while also thriving in anaerobic settings. This adaptability may provide insights into its ecological roles in nutrient cycling and interactions with other microorganisms within its habitats. Understanding the ecological implications of Y. bercovieri's metabolic capabilities can offer valuable perspectives on its potential contributions to microbial community dynamics.
