The strain is an aerobic, halophilic, thermotolerant, Gram-stain-positive bacterium, growing at NaCl concentrations between 5 and 20% (w/v) and at 43-60 degrees C and pH 5.0-10.0. The major fatty acids were iso-C-15:0, anteiso-C-15:0 and iso-C-17:0. The DNA G+C content was 53.4 mol%. LL-Diaminopimelic acid was the diamino acid of the peptidoglycan. The major menaquinone was MK-7, but MK-6 and MK-8 were also present in trace amounts. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and three unidentified phospholipids. Results of molecular and phenotypic analyses led to the description of the strain as a novel member to the genus Melghirimyces, family Thermoactinomycetaceae. Strain Nari11A(T) shows 96.7% 16S rRNA gene sequence similarity to the type strain of Melghirimyces algeriensis. On the basis of phenotypic, physiological and phylogenetic data, strain Nari11A(T) (=DSM 45514(T) =CCUG 60050(T)) represents the type strain of a novel species, for which the name Melghirimyces thermohalophllus sp. nov. is proposed. specialized ALGERIE 084 63 5 1717-1722 2013 1466-5026 https://www.documentation.ird.fr/hor/fdi:010089992 10.1099/ijs.0.043760-0 1466-5026 [F B010089992] https://www.documentation.ird.fr/hor/fdi:010089992 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2024-07/010089992.pdf IRD - Base Horizon / Pleins textes 2013-09-03 2024-07-03 fdi:010089992 fre
