Geodermatophilus normandii sp. nov., isolated from Saharan desert sand

  • A novel Gram-reaction-positive actinobacterial strain, designated CF5/3T, was isolated from a sand sample obtained in the Sahara Desert, Chad. The greenish-black-pigmented isolate was aerobic and exhibited optimal growth from 25–40 °C at pH 6.0–10.0 with 0–1 % (w/v) NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Geodermatophilus. The DNA G+C content of the genome of the novel strain was 75.5 mol%. The peptidoglycan contained meso-diaminopimelic acid as diagnostic diamino acid. The main phospholipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and a minor fraction of phosphatidylglycerol. MK-9(H4) was the dominant menaquinone, and galactose was detected as a diagnostic sugar. The major cellular fatty acids were branched-chain saturated acids: iso-C15:0 and iso-C16:0. Analysis of 16S rRNA gene sequences showed 95.6–98.8 % pairwise sequence identity with the members ofA novel Gram-reaction-positive actinobacterial strain, designated CF5/3T, was isolated from a sand sample obtained in the Sahara Desert, Chad.

Based on phenotypic and chemotaxonomic properties, as well as phylogenetic distinctiveness, the isolate represents a novel species, Geodermatophilus normandii, with the type strain CF5/3T (=DSM 45417T=CCUG 62814T=MTCC 11412T).zeige mehrzeige weniger
