User:GreyCarlsen/Nocardiopsis sinuspersici

Nocardiopsis sinuspersici is a aerobic, Gram positive, alkalohalophilic, actinomycete. While species from the genus of Nocardiopsis have been found in a variety of environments, primarily soils, strain N. sinuspersici sp. nov has been isolated from sandy rhizospheric soils from Sarbandar and Khoramshahr in Iran. N. sinuspersici have been shown to grow optimally on yeast extract agar and less optimally on agar containing oatmeal and inorganic starches (5). N. sinuspersici possess several unique phenotypic traits not seen in other members of Nocardiopsis (5). N. sisnusci possess small amounts of light yellow mycelium and "zig-zag" hyphea. Over time these hyphae form red spores (5). The cellular membrane of N. sinuspersici is also unique among other sinuspersici, most notable lacking mycolic acids (5).

Strains of N. sinuspersici can grow in a wide range of conditions, but have been found to grow best at 28 C, a pH of 7, and a salt concentration of 2.5% (5). Despite showing high similarity genetic similarity to Nocardiopsis quinghaiensis, Nocardiopsis aegyptia, and Nocardiopsis halotolerans, N. sinuspersici shows a distinguishable growth rate among other species when grown at a pH of 12, a salt concentration of 15%, and a temperature of 10 C (5). N. sinuspersici is also distinguishable from the other members of Nocardiopsis among major chemical compounds, including the producion of different sugars, phospholipid patterns, menaquinones, and fatty acids (5). N. sinuspersici sp. nov has been observed to utilize carbon sources including d-Galactose, lactose, melibiose, glycerol, sucrose, maltose, mannitol, d-mannose, l-rhamnose, d-xylose, inulin, citrate, malonate, pyruvate and propionate (5).

Genetics
The entire genome N. sinuspersici has been sequenced. 16S RNA gene sequencing of N. sinuspersici shows high similarity to other members of the genus, including Nocardiopsis quinghaiensis, Nocardiopsis aegyptia, and Nocardiopsis halotolerans matching at 99.2%, 98.5%, and 98.2% respectively (5). From a review of its genes, it has been noted that N. sinuspersici possesses a high number of genes associated with the production of secondary metabolites (6). Specifically, N. sinuspersici was shown to posses 63 gene clusters associated with the production of secondary metabolites (6). Shotgun sequences of N. sinuspersici can be found under the accession number MCOK0000000 at GenBank.
