“…The isolate hydrolyzed the gelatin, indicating proteolytic activity, but it did not hydrolyze the casein. The capability to degrade starch and Tween 80, which is present in closely related Nocardioides species (Dastager et al, 2008;Kim et al, 2008), was not observed in our strain. The phenotypic and chemotaxonomic characteristics that differentiate the strain Gsoil 485 T from other Nocardioides species are listed in Table 1.…”

“…71.6 69.9* 73 69.1 68 73 * Data was from Dastager et al (2008) recommended and accepted criteria for delineating bacterial species have stated that strains with a DNA-DNA relatedness below 70%, as measured by hybridization, or with a 16S rRNA gene sequence dissimilarity above 3%, are considered to be a separate species (Stackebrandt and Goebel, 1994). Taking into account this definition, the above mentioned data indicate that strain Gsoil 485 T has a high enough probability to be a novel species of the genus Nocardioides.…”

A Gram-positive, rod-shaped, non-spore-forming bacterium (Gsoil 485(T)) was isolated from the soil of a ginseng field located in Pocheon province in South Korea. This bacterium was characterized in order to determine its taxonomic position by using the polyphasic approach. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 485(T) was shown to belong to the family Nocardioidaceae and related to Nocardioides koreensis (96.8% 16S rRNA gene sequence similarity), Nocardioides basaltis (96.7%), Nocardioides salarius (96.7%), and Nocardioides sediminis (96.5%). The sequence similarity with other species that had validly published names within the genus Nocardioides was less than 96.4%. Strain Gsoil 485(T) was characterized chemotaxonomically as having LL-2,6-diaminopimelic acid in a cell-wall peptidoglycan, MK-8(H(4)) as the predominant menaquinone, and iso-C(16:0), C(18:1) ω9c as the major fatty acids. The G+C content of genomic DNA was 71.6 mol%. The chemotaxonomic properties and phenotypic characteristics supported the affiliation of strain Gsoil 485(T) to the genus Nocardioides. The results of both physiological and biochemical tests allowed for genotypic differentiation of strain Gsoil 485(T) from the recognized Nocardioides species. Therefore, strain Gsoil 485(T) is considered to represent the novel species, for which the name Nocardioides ginsengisegetis sp. nov. is proposed, with the type strain Gsoil 485(T) (KACC 14269(T) =KCTC 19469(T) =DSM 21349(T)).

“…The results showed that the optimal temperature range for atrazine degradation were 25 °C and 37 °C. These temperature values are close to the optimal growth temperature for Nocardioides sp., which is 28 °C (Dastager et al, 2008). This explains the negligible degradation and microbial activity observed at 4 °C, 10 °C and 45 °C.…”

Aims: To effectively exploit the atrazine degrading capabilities of Nocardioides spp. isolated from agricultural soil samples in Nigeria and ascertain the effect of pH, temperature and nutrient addition on the degradation process. Methodology and results: Isolates were cultivated on atrazine mineral salts medium at a temperature range of 4 °C-45 °C and a pH range of 3-10. An optimum atrazine degrading activity was observed in the isolates between temperatures of 25 °C and 37 °C and between pH 5 and 8. Different carbon sources (glycerine, glucose, chitin, cellulose and sodium citrate) and nitrogen sources (urea, biuret, cyanuric acid, potassium nitrate and ammonium chloride) were also added to the medium. The addition of carbon and nitrogen sources did not increase degradation rates although urea and glycerine repressed the degradation ability of the isolates. Statistical analyses of variance at P < 0.05 showed no significant differences in the growth and degradation rates by both bacterial isolates under these conditions. Conclusion, significance and impact study: Atrazine degradation by Nocardioides spp. is pH and temperature dependent, and requires no additional sources of carbon and nitrogen. Hence, its use in bioremediation of atrazine contaminated agricultural soil should be explored.

“…10MeC 16:0 FA has been proposed to be characteristic of sulfatereducing bacteria (SRB) of the genera Desulfobacter and Desulfobacula, where it is found to make up various amounts of approximately 5 to 25% of the total lipids (4,15,32,33,45,51). Besides these sulfate reducers, 10MeC 16:0 FA is also occasionally, but generally in much smaller amounts, found in other bacteria; the literature reports its presence in several actinobacteria (6,12,23,31,41,56,58), in anammox bacteria and other planctomycetes (48,49), in an iron-reducing Geobacter species (34,57), in a Marinobacter species (55), and in the marine denitrifier Pseudomonas nautica (14). Several studies report the presence of 10MeC 16:0 FA in relation to the occurrence of anaerobic methane oxidation (AOM) coupled to sulfate reduction (1,2,7,17,26,39).…”

bThe recently described bacterium "Candidatus Methylomirabilis oxyfera" couples the oxidation of the important greenhouse gas methane to the reduction of nitrite. The ecological significance of "Ca. Methylomirabilis oxyfera" is still underexplored, as our ability to identify the presence of this bacterium is thus far limited to DNA-based techniques. Here, we investigated the lipid composition of "Ca. Methylomirabilis oxyfera" to identify new, gene-independent biomarkers for the environmental detection of this bacterium. Multiple "Ca. Methylomirabilis oxyfera" enrichment cultures were investigated. In all cultures, the lipid profile was dominated up to 46% by the fatty acid (FA) 10-methylhexadecanoic acid (10MeC 16:0 ). Furthermore, a unique FA was identified that has not been reported elsewhere: the monounsaturated 10-methylhexadecenoic acid with a double bond at the ⌬7 position (10MeC 16:1⌬7 ), which comprised up to 10% of the total FA profile. We propose that the typical branched fatty acids 10MeC 16:0 and 10MeC 16:1⌬7 are key and characteristic components of the lipid profile of "Ca. Methylomirabilis oxyfera." The successful detection of these fatty acids in a peatland from which one of the enrichment cultures originated supports the potential of these unique lipids as biomarkers for the process of nitrite-dependent methane oxidation in the environment.
