“…At present, the family Nocardiopsaceae contains seven genera, namely, Nocardiopsis (Meyer, 1976), Thermobifida (Zhang et al, 1998), Streptomonospora (Cui et al, 2001), Haloactinospora , Marinactinospora (Tian et al, 2009), Murinocardiopsis (Kämpfer et al, 2010) and Spinactinospora (Chang et al, 2011). With more than 25 species and subspecies, the genus Nocardiopsis is the largest genus in the family Nocardiopsaceae.…”

Salinactinospora qingdaonensis gen. nov., sp. nov., a halophilic actinomycete isolated from a salt pond A novel halophilic, filamentous, actinomycete strain, designated CXB832 T , was isolated from a salt pond in Qingdao, China. Optimal growth occurred at 37 6C, pH 7.0-8.0 and 9-12 % (w/v) NaCl. Strain CXB832 T formed pale yellow to deep yellow branched substrate mycelium without fragmentation. Abundant white aerial mycelium differentiated into long chains of spores and the spores were rod-shaped with smooth surfaces. Strain CXB832 T contained meso-diaminopimelic acid as the diagnostic diamino acid of the cell-wall peptidoglycan, and glucose and xylose as the major whole-cell sugars. The phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phospholipids, glycolipid and unidentified lipids. MK-10(H 8 ), MK-9(H 8 ), MK-10(H 2 ) and MK-10(H 6 ) were the predominant menaquinones. The major fatty acids were i-C 16 : 0 (30.71 %), ai-C 17 : 0 (13.31 %) and C 16 : 0 (11.28 %). The G+C content of the DNA was 60.1 mol%. Comparative analysis of 16S rRNA gene sequences showed that the novel strain was most closely related to genera within the family Nocardiopsaceae, but formed a separate lineage. The highest sequence similarities were to Nocardiopsis arabia DSM 45083 T (95.4 %) and Haloactinospora alba DSM 45015 T (94.9 %). On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain CXB832 T represents a new genus and novel species in the family Nocardiopsaceae, for which the name Salinactinospora qingdaonensis gen. nov., sp. nov. is proposed. The type strain of the type species is CXB832 T (5DSM 45442 T 5LMG 25567 T ).

“…Genomic DNA was extracted by following the methods of Cui et al (2001). The nearly complete 16S rRNA gene sequence of the novel strain was obtained by PCR amplification using the universal primers 27f (59-AGAGTTTATCCTGGCTCAG-39) and 1492r (59-TACCTTGTTACGACTT-39) (Lane, 1991).…”

The taxonomic status of a methyl-parathion-degrading strain, OP-1 T , isolated from a wastewatertreatment system in China, was determined using a polyphasic approach. The rod-shaped cells were Gram-staining-negative, non-spore-forming and non-motile. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain belonged to the genus Burkholderia, as it appeared closely related to Burkholderia glathei ATCC 29195 T (97.4 % sequence similarity), Burkholderia sordidicola KCTC 12081 T (96.5 %) and Burkholderia bryophila LMG 23644 T (96.3 %). The major cellular fatty acids, C 16 : 0 , C 17 : 0 cyclo and C 18 : 1 v7c, were also similar to those found in established members of the genus Burkholderia. The genomic DNA G+C content of strain OP-1 T was 59.4 mol%. The level of DNA-DNA relatedness between the novel strain and the closest recognized species, Burkholderia glathei ATCC 29195 T , was only 30 %. Based on the phenotypic, genotypic and phylogenetic evidence, strain OP-1 T represents a novel species of the genus Burkholderia, for which the name Burkholderia zhejiangensis sp. nov. is proposed. The type strain is OP-1 T (5CCTCC AB 2010354 T 5KCTC 23300 T ).Methyl parathion (O,O-dimethyl O-p-nitrophenylphosphorothioate; MP) is widely used to control a large range of insect pests. Like other organophosphorus pesticides, MP kills insects by inhibiting their acetyl cholinesterase, in an irreversible manner (Karalliedde & Senanayake, 1989). Unfortunately, as acetyl cholinesterase occurs in all vertebrates, the potential for organophosphorus pesticides causing damage to humans and other vertebrates is very high (Dumas et al., 1989;Sogorb et al., 2004). Soil microorganisms can play a significant role in the bioremediation of pesticide-contaminated soil, and various MP-degrading soil bacteria have already been isolated and characterized (Chaudhry et al., 1988;Hayatsu et al., 2000;Liu et al., 2005;Zhang et al., 2006;Shen et al., 2010).Burkholderia is a genus of metabolically versatile Gramstaining-negative bacteria. The genus was first proposed by Yabuuchi et al. (1992), who transferred seven species from rRNA group II of the genus Pseudomonas to the novel genus. Many species of the genus Burkholderia play an important role in the biodegradation of pollutants (Coenye & Vandamme, 2003;Lehning et al., 1997;Hayatsu et al., 2000). In this paper, the taxonomy of an MP-degrading bacterium, designated strain OP-1 T , was investigated using a polyphasic approach, The new strain was eventually identified as a novel species in the genus Burkholderia.In 2008, a conventional enrichment method was employed in an attempt to isolate MP-degrading bacteria from sludge collected from the wastewater-treatment system of a pesticidemanufacturing company in the Chinese province of Zhejiang. A subsample (1 g) of the collected sludge was inoculated into an MP-supplemented mineral salts medium (MP-MSM) which contained (l 21 ): 1.5 g K 2 HPO 4 , 0.5 g KH 2 PO 4 , 1.0 g NH 4 NO 3 , 0.2 g MgSO 4 . 7H 2 O, 0.5 g NaCl and, as the so...

“…Members of a new suborder, Jiangellineae [4], Zhihengliuella [5], Haloactinospora [6], Haloglycomyces [7], Amycolicicoccus [8], Yimella [9] and Sinococcus [10] were discovered in saline soil. Members of 6 new genera, Streptomonospora [11], Sediminimonas [12], Haloactinopolyspora [1], Alkalibacillus [13], Salinimicrobium [14] and Aidingimonas [15] were found in salt lakes and mines. We conclude that new bacterial taxa are surprisingly common in extreme environments, especially in hypersaline and alkaline habitats (Table 1).…”

Extreme environments, primeval forest, sea sediments and plants in China yielded members of a new suborder, Jiangellineae, a new family Sinobacteraceae, and 23 new genera of actinomycetes and other bacteria. Three suggestions were made for further discoveries of new actinomycetes. First, natural habitats such as old growth forests, and extreme environments, should be given sampling priority; second, culturing procedures need to be constantly improved to mimic natural habitats; third, less than 98.5% similarity of 16S rRNA sequence to that of a known species could be used as an indicator of a new species. Extensive hypersaline and alkaline soils, deserts, and more than 100 salt lakes are found in Xinjiang Uyghur Autonomous Region, Qinghai and Gansu provinces, northwestern China. We collected 535 soil and lake sediment samples from these provinces and autonomous region between 1993 and 2008. Actinomycetes and other bacteria were isolated from these samples using dilution plate techniques involving 12 different media. Isolates were purified, and then identified using a polyphasic taxonomic approach. Large numbers of new bacterial taxa were discovered from the isolates, described and published. Members of a new suborder, Jiangellineae [1], were found in primeval desert soil in Gansu Province (Figure 1 and Aidingimonas [15] were found in salt lakes and mines. We conclude that new bacterial taxa are surprisingly common in extreme environments, especially in hypersaline and alkaline habitats (Table 1).There are extensive natural forests, which are wellprotected from the actions of humans, in and around Yunnan Province. Members of 3 new genera, Actinobispora [16], Actinomycetospora [17] and Planosporangium [18] were found in soil samples collected from tropical rain forest in Xishuangbanna, Yunnan. A member of a new genus, Naxibacter [19], was found in coniferous forest at an elevation of 3700 m in Lijiang, northwestern Yunnan. A
