Prosthecobacter algae sp. nov., isolated from activated sludge using algal metabolites.

A Gram-stain-negative, fusiform-shaped, facultatively anaerobic bacterial strain, designated EBTL04(T), was isolated from activated sludge using algal metabolites and taxonomically characterized through polyphasic investigation. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain EBTL04(T) belongs to the family Verrucomicrobiaceae, class Verrucomicrobiae, and is closely related to Prosthecobacter dejongeii DSM 12251(T) (98.6 % sequence similarity), Prosthecobacter fusiformis ATCC 25309(T) (97.
