Strain LMG 24366T was isolated from a marine electroactive biofilm grown on a stainless steel cathode (Genova, Italy) and was investigated by using a polyphasic taxonomic approach. This study demonstrated that strain LMG 24366T represents a novel species within the genus Leisingera, which shared 98.9?% 16S rRNA gene similarity with its nearest phylogenetic neighbour, Leisingera methylohalidivorans. Strain LMG 24366T grew on betaine (1 mM) as a sole carbon source, whereas no growth was observed on l-methionine (10 mM). The phenotypic and genotypic analyses showed that strain LMG 24366T could be differentiated from established Leisingera species and that it represented a novel species, for which the name Leisingera aquimarina sp. nov. is proposed. The type strain is LMG 24366T (=CCUG 55860T) and has a DNA G+C content of 61.4 mol%. |
