A novel strain of the genus Promicromonospora, designated HM 792T, was isolated from soil in Fars Province, Iran. On ISP 2 medium, the yellow-pigmented isolate produced long and branched hyphae that developed into a large number of irregularly shaped spores. It showed growth at 25–30 °C and pH 6.0–9.0 with 0–8 % (w/v) NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Promicromonospora. Whole-cell hydrolysates of strain HM 792T contained the amino acids d-glutamic acid, l-alanine and l-lysine along with the sugars glucose and ribose. The main polar lipids were diphosphatidylglycerol, two unknown phospholipids, two unknown glycolipids and two unknown phosphoglycolipids, complemented by minor concentrations of phosphatidylinositol and phosphatidylglycerol. MK-9(H4) was the predominant menaquinone. The fatty-acid pattern was composed mainly of the saturated branched-chain acids anteiso-C15 : 0 and iso-C15 : 0. 16S rRNA gene sequence analysis showed the highest pairwise sequence identity (96.6–99.0 %) with the members of the genus Promicromonospora. Based on phenotypic and genotypic features, strain HM 792T is considered to represent a novel species of the genus Promicromonospora, for which the name Promicromonospora iranensis sp. nov. is proposed. Strain HM 792T ( = DSM 45554T = UTMC00792T = CCUG 63022T) is the type strain.
