Phytomonospora cypria sp nov., isolated from soil

Abstract

A Gram-stain positive actinobacterial strain, designated KT1403(T), was isolated from a soil sample, collected from Karpaz, Magusa, Northern Cyprus, and characterised using a polyphasic approach. Morphological characteristics and chemotaxonomic data indicated that the strain belongs to the genus Phytomonospora. The cell wall of the novel strain contained meso-diaminopimelic acid and galactose, glucose and mannose as the major sugars in whole cell hydrolysates. The polar lipids in the cell membrane were identified as diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, an unidentified aminophospholipid and three unidentified glycolipids. The predominant menaquinones were MK-10(H-6) and MK-10(H-4). The major fatty acids were found to be iso C-15:0 , anteiso C-15:0 and anteiso C-17:0. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain KT1403(T) belongs to the genus Phytomonospora with a sequence similarity of 99.73 % with Phytomonospora endophytica, the type species of the genus. DNA-DNA hybridization further differentiated strain KT1403(T) from its near phylogenetic neighbour, P. endophytica DSM 45386(T) (29.0 +/- A 2.2 % DNA relatedness). Therefore, it is proposed that strain KT1403(T) represents a novel species of the genus Phytomonospora, for which the name Phytomonospora cypria sp. nov. is proposed. The type strain is KT1403(T) (=KCTC 29479(T) = DSM 46767(T)).
