“…The three acidophilic isolates from the F-horizon of the spruce forest soil at Hamsterley Forest were found to share a range of cultural, chemotaxonomic and morphological properties typical of members of the genus Streptacidiphilus (Kim et al 2003; Huang et al 2004; Wang et al 2006; Cho et al 2008). They were shown to form extensively branched substrate mycelia, white to medium gray aerial hyphae that were found to differentiate into straight to flexuous chains of spores on oatmeal agar; and to have whole-organism hydrolysates rich in ll -A 2 pm, galactose and rhamnose, MK-9 (H 6 , H 8 ) as the predominant isoprenologues; and diphosphatidylglycerol, phophatidylethanolamine (diagnostic lipid), phosphatidylinositol and phosphatidylinositol mannosides as major polar lipids (phospholipid pattern 2 after Lechevalier et al 1977).…”

“…These organisms are numerous and widely distributed in acidic habitats, notably coniferous soils (Williams et al 1971; Khan and Williams 1975; Goodfellow and Dawson 1978; Cho et al 2008) where they have a role in the turnover of fungal biomass (Williams and Robinson 1981). They are a source of antifungal compounds (Williams and Khan 1974) and produce chitinases and diastases with pH optima below those of neutrophilic streptomycetes (Williams and Flowers 1978).…”

The taxonomic position of three acidophilic actinobacteria, strains FGG38, FGG39 and FSCA67T, isolated from the fermentation litter layer of a spruce forest soil was established using a polyphasic approach. The strains were shown to have chemotaxonomic and morphological properties consistent with their classification in the genus Streptacidiphilus and formed a distinct phyletic line in the Streptacidiphilus 16S rRNA gene tree being most closely related to Streptacidiphilus albus DSM 41753T (99.4 % similarity). DNA:DNA relatedness data showed that isolate FSCA67T and the type strain of S. albus belonged to markedly distinct genomic species. The isolates had many phenotypic properties in common and were distinguished readily from their closest phylogenetic neighbours in the Streptacidiphilus gene tree using a broad range of these features. Based on the combined genotypic and phenotypic data the three isolates are considered to represent a new Streptacidiphilus species. The name Streptacidiphilus durhamensis sp. nov. is proposed for this taxon with isolate FSCA67T (=DSM 45796T = KACC 17154T = NCIMB 14829T) as the type strain.

“…In this study, it is evident that some genera not commonly found in the mangrove environment were discovered, such as Streptacidiphilus , Sinomonas , Terrabacter, and Leifsonia . So far, the different species of Streptacidiphilus were isolated from area such as Pinus soils [44], acidic rhizosphere soil [45], and rice field soil [46], while Sinomonas was mostly discovered in forest soils [47], polluted forest soil [48], and volcanic soil [49]. …”

The aim of this study was to isolate and identify Actinobacteria from Malaysia mangrove forest and screen them for production of antimicrobial secondary metabolites. Eighty-seven isolates were isolated from soil samples collected at 4 different sites. This is the first report to describe the isolation of Streptomyces, Mycobacterium, Leifsonia, Microbacterium, Sinomonas, Nocardia, Terrabacter, Streptacidiphilus, Micromonospora, Gordonia, and Nocardioides from mangrove in east coast of Malaysia. Of 87 isolates, at least 5 isolates are considered as putative novel taxa. Nine Streptomyces sp. isolates were producing potent antimicrobial secondary metabolites, indicating that Streptomyces isolates are providing high quality metabolites for drug discovery purposes. The discovery of a novel species, Streptomyces pluripotens sp. nov. MUSC 135T that produced potent secondary metabolites inhibiting the growth of MRSA, had provided promising metabolites for drug discovery research. The biosynthetic potential of 87 isolates was investigated by the detection of polyketide synthetase (PKS) and nonribosomal polyketide synthetase (NRPS) genes, the hallmarks of secondary metabolites production. Results showed that many isolates were positive for PKS-I (19.5%), PKS-II (42.5%), and NRPS (5.7%) genes, indicating that mangrove Actinobacteria have significant biosynthetic potential. Our results highlighted that mangrove environment represented a rich reservoir for isolation of Actinobacteria, which are potential sources for discovery of antimicrobial secondary metabolites.

Strep.to.my'ces. Gr. adj. streptos pliant, bent; Gr. masc. n. mukês fungus; N.L. masc. n. Streptomyces pliant or bent fungus. Actinobacteria / Actinobacteria / Streptomycetales / Streptomycetaceae / Streptomyces Aerobic, Gram‐stain‐positive, non‐acid‐fast bacteria that form extensively branched substrate and aerial mycelia . Chemoorganotrophic, having an oxidative type of metabolism. The vegetative hyphae (0.5–2.0 µm in diameter) rarely fragment. The aerial mycelium forms chains of three to many spores at maturity . Some species show short chains of spores on the substrate mycelium and others form sclerotia, pycnidial‐, sporangia‐, and synnemata‐like structures. The spores are nonmotile. Colonies are discrete and lichenoid, leathery, or butyrous . Often, colonies initially show a smooth surface, but later develop a weft of aerial mycelium that may appear floccose, granular, powdery, or velvety. Can produce a wide variety of pigments responsible for the color of the vegetative and aerial mycelia. Colored diffusible pigments may also be formed . Many strains are able to produce one or more antibiotic substances. DNA G + C content ( mol %): 66–78 ( T m ). Type species : Streptomyces albus (Rossi Doria 1891) Waksman and Henrici 1943, 339 AL .
