Flavobacterium rivuli WB 3.3-2 = DSM 21788 strain WB 3.3-2

Flavobacterium rivuli WB 3.3-2 (DSM 21788) is a Gram-negative, rod-shaped bacterium that exhibits an aerobic metabolism and thrives optimally at a temperature of 16.0°C. This strain belongs to the genus Flavobacterium, known for its diverse ecological roles, particularly in aquatic environments. As a member of the Flavobacteriaceae family, F. rivuli WB 3.3-2 may contribute to the decomposition of organic matter, playing a significant role in nutrient cycling within its ecological niche. The Gram-negative cell wall structure of F. rivuli WB 3.3-2 is characterized by a thin peptidoglycan layer surrounded by an outer membrane containing lipopolysaccharides, which may provide advantages in specific habitats by facilitating interactions with other microbial communities. Its rod shape is typical of many members of this genus, allowing for efficient motility and nutrient uptake in aqueous environments. Given its optimal growth temperature of 16.0°C, F. rivuli WB 3.3-2 is likely adapted to cooler aquatic habitats, such as freshwater lakes or rivers. This temperature preference suggests that it may play an essential role in the microbial communities of cold-water ecosystems, where it could influence the decomposition processes and the overall carbon cycle. Understanding the ecological functions of this strain may provide insights into the dynamics of microbial communities in similar environments, highlighting the significance of temperature in shaping microbial diversity and activity.
