“…In summary, strain HBUM 20038 T can be classified in the genus Nocardiopsis based on 16S rRNA gene sequence (Schippers et al, 2002); 4, N. exhalans DSM 44407 T (Peltola et al, 2001); 5, N. alba DSM 43377 T ; 6, N. aegyptia DSM 44442 T (Sabry et al, 2004); 7, N. lucentensis DSM 44048 T ; 8, N. listeri DSM 40297 T . Unless indicated, data were taken from Evtushenko et al (2000).…”

An actinomycete, strain HBUM 20038 T , was isolated from soil from Ganjiahu Natural Reserve in Xinjiang Province, in north-western China, and then characterized using a polyphasic approach. 16S rRNA gene sequence analysis confirmed that strain HBUM 20038 T was a member of the genus Nocardiopsis, and the morphological and chemotaxonomic characteristics of the strain were also consistent with those of species of Nocardiopsis. DNA-DNA hybridization between the strain and related type strains gave relatedness values far below 70 %. These results, together with physiological characteristics, showed that strain HBUM 20038 T represents a novel species within the genus Nocardiopsis, for which the name Nocardiopsis ganjiahuensis sp. nov. is proposed. The type strain is HBUM 20038 T (5DSM 45031 T 5CGMCC 4.3500 T ).

Secretion of an alkaline protease from a salt- tolerant and alkaliphilic, Streptomyces clavuligerus strain Mit-1

An alkaliphilic and salt-tolerant actinomycete, Streptomyces clavuligerus strain Mit-1, was isolated from Mithapur, the western coast of India. The organism was Gram-positive, having filamentous, long thread like structure. The sporulation started after two days of growth and the optimum level of alkaline protease (130 U/ ml) was produced during the early stationary phase. The strain could grow and produce protease with 0-10% NaCl (w/v), the optimum being 5% NaCl (w/v). Growth and protease production was optimum at pH 9 with substantial decline at neutral pH. Sucrose and gelatin were the best carbon and nitrogen sources respectively, whereas gelatin broth was the preferred medium for protease production. Mit-1 produced substantial protease with various amino acids, when employed as the sole nitrogen sources. Crude substrates, such as molasses, whey and wheat flour had significant effect on enzyme production. The results are quite valuable, as only few actinomycetes, particularly salt-tolerant alkaliphilic ones, have so far been explored for their enzymatic potential and process optimization.

“…At the time of writing, the taxon encompasses 24 recognized species (Li et al, 2006), which form a distinct clade within the evolutionary radiation occupied by members of the family Nocardiopsaceae (Rainey et al, 1996;Cui et al, 2001;Kroppenstedt & Evtushenko, 2006). Nocardiopsis strains are frequently isolated from saline and alkaline soils (Li et al, , 2006Hozzein et al, 2004), but have also been recovered from an alkaline slag dump (Schippers et al, 2002), clinical material (Yassin et al, 1997;Mordarska et al, 1998), indoor environments (Peltola et al, 2001), the atmosphere of a composting facility (Kämpfer et al, 2002) and a marine sediment (Sabry et al, 2004). In the present polyphasic study, an actinomycete isolated from a sand-dune soil was shown to represent a novel species of the genus Nocardiopsis.…”

The taxonomic status of an unknown actinomycete isolated from a sand-dune soil was established using a polyphasic approach. Isolate S186T had chemotaxonomic and morphological properties consistent with its classification in the genus Nocardiopsis, grew on agar plates at NaCl concentrations of up to 15 % (w/v) and formed a distinct phyletic line in the Nocardiopsis 16S rRNA gene sequence tree. Its closest phylogenetic neighbours were Nocardiopsis chromatogenes, Nocardiopsis composta, Nocardiopsis gilva and Nocardiopsis trehalosi, with sequence similarity to the various type strains of 96.9 %, but it was readily distinguished from the type strains of these and related species using a range of phenotypic properties. It is apparent from the genotypic and phenotypic data that strain S186 T belongs to a novel species of the genus Nocardiopsis, for which the name Nocardiopsis arabia sp. nov. is proposed. The type strain is S186 T (5CGMCC 4.2057 T 5DSM 45083 T ).
