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

Flavobacterium rivuli WB 3.3-2, also known as DSM 21788, is a Gram-negative, aerobic, non-motile bacterium characterized by its rod shape. This strain exhibits psychrotolerant properties, with an optimal growth temperature of 16°C, indicating its capacity to thrive in cooler environments. The presence of a single replicon suggests a streamlined genomic organization, which can be advantageous for adaptation to specific ecological niches. As a member of the Flavobacterium genus, this strain is likely to play a role in the decomposition of organic matter in aquatic environments, particularly in cold waters, where it may contribute to nutrient cycling. The ability to grow at low temperatures positions Flavobacterium rivuli WB 3.3-2 as an important organism in polar and temperate ecosystems, where it may interact with other microbial communities and influence the dynamics of these habitats. The strain is cataloged with the accession number JRLX00000000.1, providing a reference for future genomic studies. Its non-motile nature, coupled with aerobic metabolic requirements, suggests that it relies on passive transport mechanisms for nutrient acquisition in its environment. Overall, Flavobacterium rivuli WB 3.3-2 exemplifies how specific microbial traits can inform our understanding of ecological roles and interactions in cold aquatic ecosystems.
