A novel halophilic, filamentous, actinomycete strain, designated YIM 90648(T), was isolated from a salt lake in Xinjiang Province, north-west China, and subjected to a polyphasic taxonomic study. Optimal growth occurred at 37 degrees C, pH 7.0-8.0 and 15% (w/v) NaCl. The aerial mycelium of strain YIM 90648(T) formed long chains of spores at maturity and the(More)
A halophilic actinomycete strain, designated YIM 91168T, was isolated from a salt lake in Xinjiang province, north-west China. The isolate grew at 20-40 degrees C, pH 5-8 and 6-22% (w/v) NaCl; there was no growth in the absence of NaCl. The whole-cell hydrolysate contained meso-diaminopimelic acid, galactose and arabinose. The major fatty acids were(More)
A Gram-staining-positive, facultatively anaerobic, non-motile and moderately halophilic actinobacterium, designated YIM 93306(T), was isolated from a salt lake in Xinjiang province, north-west China, and subjected to a polyphasic taxonomic study. Strain YIM 93306(T) grew in the presence of 2-16 % (w/v) NaCl and did not grow without NaCl. The peptidoglycan(More)
Strains YIM 90625(T), YIM 90630(T), YIM 90636(T) and YIM 90694(T) were isolated from a salt lake in Xinjiang province, north-west China, and were subjected to a polyphasic analysis to determine their taxonomic positions. All isolates were moderately halophilic and were able to grow at NaCl concentrations up to 15 or 20 % (w/v). The genomic DNA G+C contents(More)
A novel halophilic actinobacterium, designated YIM 92370(T), was isolated from a hypersaline habitat in Xinjiang Province, north-west China. The strain was aerobic, Gram-positive-staining and halophilic, with an optimum NaCl concentration for growth of 8-12 % (w/v). The whole-cell sugar pattern consisted of ribose, xylose and glucose. The predominant(More)
A Gram-stain-positive, coccoid, non-motile, halotolerant actinobacterium, designated YIM 45900(T), was found as a contaminant on an agar plate in the laboratory of Yunnan Institute of Microbiology, China. The peptidoglycan type was A4alpha with an (L)-Lys-(L)-Ser-(D)-Asp interpeptide bridge. The cell-wall sugars contained galactose and fucose. The(More)
The genera Actinopolyspora and Streptomonospora are two groups of extremely halophilic filamentous actinomycetes. Members of these two genera are isolated frequently, probably due to the high occurrence of these actinomycetes in the hypersaline soil environment. Although members of these genera can be identified by micromorphological criteria, the extensive(More)
The genus Nocardiopsis is a widespread group within the phylum Actinobacteria and has been isolated from various salty environments worldwide. However, little is known about whether biogeography affects Nocardiopsis distribution in various hypersaline environments. Such information is essential for understanding the ecology of Nocardiopsis. Here we analyzed(More)
A Gram-positive, milk-white coloured, aerobic strain, YIM 48868T, was isolated from the rhizosphere soil of Maytenus hookeri Loes in Xishuangbanna, China. 16S rRNA gene sequence similarity studies showed that strain YIM 48868T was a member of the genus Actinopolymorpha, showing 96.8% sequence similarity to Actinopolymorpha singaporensis IM 7744T and 97.0%(More)
