“…Achromobacter xylosoxidans has been previously shown to degrade gaseous toluene [31], the synthetic chelating agent iminodisuccinate [32], endosulfan, endosulfan sulfate [33,34], p-nitrophenol [35] and bisphenol A [36]. A. xylosoxidans has also been shown to degrade 2-chlorobenzoate and 2, 5-dichlorobenzoate and utilize them as sole sources of carbon and energy [37].…”

Heterotrophic carbon utilizing microbes were acclimatized in the laboratory by inoculating sludge collected from the waste discharge pond of a small-scale rural abattoir in India in a nutrient solution intermittently fed with glucose and ammonium chloride. Cultures of 10 well-developed isolates were selected and grown in a basal medium containing glucose and ammonium chloride. Culture supernatants were periodically analyzed for ammonium nitrogen (NH(4)(+)-N) and chemical oxygen demand (COD). Polyphasic taxonomic study of the most active nitrifier (S18) was done. Half saturation concentration (K(s)), maximum rate of substrate utilization (k), yield coefficient (Y) and decay coefficient (K(d)) were determined from the Lineweaver-Burk plot using the modified Monod equation. S18 was able to remove 97 ± 2% of (NH(4)(+)-N) and 88 ± 3% of COD. Molecular phylogenetic study supported by physiological and biochemical characteristics assigned S18 as Achromobacter xylosoxidans. Nitrification activity of A. xylosoxidans was demonstrated for the first time, while interestingly, the distinctive anaerobic denitrification property was preserved in S18. K (s) values were determined as 232.13 ± 1.5 mg/l for COD reduction and 2.131 ± 1.9 mg/l for NH(4)(+)-N utilization. Yield coefficients obtained were 0.4423 ± 0.1134 mg of MLVSS/mg of COD and 0.2461 ± 0.0793 mg of MLVSS/mg of NH(4)(+)-N while the decay coefficients were 0.0627 ± 0.0013 per day and 0.0514 ± 0.0008 per day, respectively. After a contact period of 24 h, 650 ± 5 mg/l solids were produced when the initial concentration of COD and NH(4)(+)-N were 1820 ± 10 mg/l and 120 ± 5.5 mg/l, respectively. This is the first report on the kinetic coefficients for carbon oxidation and nitrification by a single bacterium isolated from slaughterhouse wastewater.

“…have been known for their abilities to biodegrade methyl tert-butyl ether (Eixarch and Constanti 2010), p-nitrophenol (Wan et al 2007), bisphenol (Zhang et al 2007), endosulfan (Li et al 2009), and hexavalent chromium (Zhu et al 2008) and to catalyze the asymmetric acyloin condensation reaction (Guo et al 2001) but not the reduction of alkenes. Bacteria from other genera such as Pseudomonas, Bacillus, Clostridium, Ruminococcus, Acetobacterium, Zymomonas, and Agrobacterium have been reported to contain enoate reductases (Toogood et al 2010).…”

The strain Achromobacter sp. JA81, which produced enoate reductase, was applied in the asymmetric reduction of activated alkenes. The strain could catalyze the bioreduction of alkenes to form enantiopure (R)-β-aryl-β-cyano-propanoic acids, a precursor of (R)-γ-amino butyric acids, including the pharmaceutically active enantiomer of the chiral drug (R)-baclofen with excellent enantioselectivity. It could catalyze as well the stereoselective bioreduction of other activated alkenes such as cyclic imides, β-nitro acrylates, and nitro-alkenes with up to >99 % ee and >99 % conversion. The draft genome sequencing of JA81 revealed six putative old yellow enzyme homologies, and the transcription of one of them, Achr-OYE3, was detected using reverse transcription polymerase chain reaction. The recombinant Escherichia coli expressing Achr-OYE3 displayed enoate reductase activity toward (Z)-3-cyano-3-phenyl-propenoic acid (2a).

“…Achromobacter xylosoxidans CS5 (Wen et al 2009) was capable of utilizing endosulfan as the sole carbon, sulfur and energy source. However, in their study endosulfan diol and endosulfan ether were formed as the major metabolites in the aqueous medium.…”

Endosulfan is one of the most widely used wide spectrum cyclodiene organochlorine insecticide. In environment, endosulfan can undergo either oxidation or hydrolysis reaction to form endosulfan sulfate and endosulfan diol respectively. Endosulfan sulfate is as toxic and as persistent as its parent isomers. In the present study, endosulfan degrading bacteria were isolated from soil through selective enrichment technique using sulfur free medium with endosulfan as sole sulfur source. Out of the 8 isolated bacterial strains, strain C8B was found to be the most efficient endosulfan degrader, degrading 94.12% α-endosulfan and 84.52% β-endosulfan. The bacterial strain was identified as Achromobacter xylosoxidans strain C8B on the basis of 16S rDNA sequence similarity. Achromobacter xylosoxidans strain C8B was also found to degrade 80.10% endosulfan sulfate using it as sulfur source. No known metabolites were found to be formed in the culture media during the entire course of degradation. Besides, the bacterial strain was found to degrade all the known endosulfan metabolites. There was marked increase in the quantity of released CO(2) from the culture media with endosulfan as sulfur source as compared to MgSO(4) suggesting that the bacterial strain, Achromobacter xylosoxidans strain C8B probably degraded endosulfan completely through the formation of endosulfan ether.
