Abstract

Seventy isolates were obtained from a marine electroactive biofilm that was generated on a cathodically polarized stainless steel electrode (Genoa, Italy). The genetic diversity was investigated by means of BOX-PCR fingerprinting and two clusters of isolates with similar BOX-PCR profiles were delineated. Whole-cell fatty acid methyl ester analysis and 16S rRNA gene sequence analysis showed that the isolates belonged to the lineage of the class . DNA–DNA hybridization experiments and a biochemical analysis demonstrated that four isolates belonged to the species . However, 66 isolates from the second BOX-PCR cluster constituted a novel species within the genus , for which the name sp. nov. is proposed. The DNA G+C content was 61.0±0.4 %. The type strain is LMG 24367 (=CCUG 55858).
