Abstract

A Gram-positive, coccoid-shaped organism (strain 02-Je-010(T)), forming yellow-pigmented colonies was isolated from the wall of an indoor environment. On the basis of 16S rRNA gene sequence similarity studies, it was shown that strain 02-Je-010(T) belongs to the genus Citricoccus with sequence similarities of 98.9 % to Citricoccus alkalitolerans DSM 15665(T) and 98.6 % to Citricoccus muralis DSM 14442(T). Cell-wall sugars were mannose and glucose. The diagnostic diamino acid of the peptidoglycan was lysine. The major menaquinones detected were MK-9(H(2)) and MK-8(H(2)). The polar lipid profile consisted of the major lipids diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol and moderate amounts of two unknown phospholipids and two unknown glycolipids. The fatty acid profile comprised major amounts of anteiso-C(15 : 0), anteiso-C(17 : 0) and iso-C(15 : 0). All these data supported the affiliation of strain 02-Je-010(T) to the genus Citricoccus. The results of DNA-DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 02-Je-010(T) from the two recognized Citricoccus species. For these reasons, strain 02-Je-010(T) represents a novel species, for which the name Citricoccus parietis sp. nov. is proposed, with the type strain 02-Je-010(T) (=CCUG 57388(T)=CCM 7609(T)).
