proximotubulusella

Proximotubulusella is a genus of bacteria from the family Rhodospirillaceae. It was first described in 2016 and is characterized by its unique morphological features and phylogenetic position within the bacterial domain. The genus includes two known species, Proximotubulusella marina and Proximotubulusella aquatica, both of which are marine isolates.

Proximotubulusella bacteria are Gram-negative, non-motile, and rod-shaped. They are obligately aerobic and chemoorganotrophic, utilizing a variety of organic compounds as carbon and energy sources. The genus is notable for its ability to form tubules, which are structures that are not typically observed in other members of the Rhodospirillaceae family.

The genus Proximotubulusella was first isolated from marine sediments and has since been found in various marine environments. Its unique characteristics and phylogenetic position suggest that it may represent a novel lineage within the bacterial domain, warranting further study to better understand its ecology, physiology, and potential applications.
