“…A steady flow of filamentous actinobacteria recovered from other nonpolar deserts have been validly named as new species, they include Amycolatopsis desertii (Busarakam et al ), Desertiactinospora gelatinilytica (Saygin et al ), Nakamurella deserti (Liu et al , b), Prauserella isguensis (Saker et al ), Saccharothrix algeriensis (Zitouni et al ), Saccharothrix tharensis (Ibeyaima et al ) and Streptosporangium becharense (Chaouch et al ).…”

Summary The prevalence of multidrug‐resistant microbial pathogens due to the continued misuse and overuse of antibiotics in agriculture and medicine is raising the prospect of a return to the preantibiotic days of medicine at the time of diminishing numbers of drug leads. The good news is that an increased understanding of the nature and extent of microbial diversity in natural habitats coupled with the application of new technologies in microbiology and chemistry is opening up new strategies in the search for new specialized products with therapeutic properties. This review explores the premise that harsh environmental conditions in extreme biomes, notably in deserts, permafrost soils and deep‐sea sediments select for micro‐organisms, especially actinobacteria, cyanobacteria and fungi, with the potential to synthesize new druggable molecules. There is evidence over the past decade that micro‐organisms adapted to life in extreme habitats are a rich source of new specialized metabolites. Extreme habitats by their very nature tend to be fragile hence there is a need to conserve those known to be hot‐spots of novel gifted micro‐organisms needed to drive drug discovery campaigns and innovative biotechnology. This review also provides an overview of microbial‐derived molecules and their biological activities focusing on the period from 2010 until 2018, over this time 186 novel structures were isolated from 129 representatives of microbial taxa recovered from extreme habitats.

A polyphasic taxonomic study was carried out on an actinobacterial strain (AN110305T) isolated from soil sampled in the Republic of Korea. Cells of the strain were Gram-stain-positive, aerobic, non-motile and rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of strain AN110305T with Actinomycetia , with highest pairwise sequence similarities to Goodfellowiella coeruleoviolacea DSM 43935T (97.6%), Umezawaea tangerina MK27-91F2T (97.0%), Kutzneria chonburiensis NBRC 110610T (96.9%), Kutzneria buriramensis A-T 1846T (96.8%), Umezawaea endophytica YIM 2047XT (96.8%), Kutzneria albida NRRL B-24060T (96.7%) and Saccharothrix coeruleofusca NRRL B-16115T (96.6%). Cells of strain AN110305T formed pale-yellow colonies on Reasoner's 2A agar. MK-9 (H4) (68%) and MK-10 (H4) (32%) were the predominant menaquinones. Diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethyl ethanolamine, hydroxy-phosphatidylethanolamine, an unidentified aminolipid and an unidentified aminophospholipid were major polar lipids. Iso-C16:0 (24.5%), anteiso-C15:0 (19.3%), anteiso-C17:0 (15.7%) and iso-C15:0 (15.2%) were the major fatty acids and meso-diaminopimelic acid was the pepdidoglycan. The cell-wall sugars were composed of galactose, glucose, mannose and ribose. The genomic DNA G+C content was 70.7 mol%. Based on genotypic and phenotypic data, strain AN110305T could be distinguished from all genera within the family Pseudonocardiaceae and represents a novel genus and species named Solihabitans fulvus gen. nov., sp nov. The type strain is AN110305T (=KCTC 39307T =DSM 103572T).
