A Gram-stain-negative, fusiform-shaped, facultatively anaerobic bacterial strain, designated EBTL04T, 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 EBTL04T belongs to the family Verrucomicrobiaceae, class Verrucomicrobiae, and is closely related to Prosthecobacter dejongeii DSM 12251T (98.6% sequence similarity), Prosthecobacter fusiformis ATCC 25309T (97.9 %), Prosthecobacter debontii DSM 14044T (97.5 %), Prosthecobacter vanneervenii DSM 12252T (94.7 %) and Prosthecobacter fluviatilis KCTC 22182T (93.7 %). The G+C content of the genomic DNA of strain EBTL04T was 62.7 mol%. The menaquinone MK-6 was detected as the predominant quinone. Strain EBTL04T contained phosphatidylethanolamine, phosphatidylglycerol and phosphatidylserine as major polar lipids. A fatty acid profile with C16: 1ω5c, iso-C14: 0, C16: 0, anteiso- C15: 0 and C14: 0 as the major components supported the classification of strain EBTL04T in the genus Prosthecobacter. Based on several phenotypic, genotypic and chemotaxonomic features, strain EBTL04T was clearly differentiated from its phylogenetic neighbours. Therefore, strain EBTL04T should be considered to represent a novel species of the genus Prosthecobacter, for which the name Prosthecobacter algae sp. nov. is proposed. The type strain is EBTL04T (5KCTC 23681T5JCM 18053T).
