“…It was revealed that the inoculation of A. xylosoxidans F3B to Arabidopsis thaliana resulted in a significant increase in root length and fresh weight [Ho et al, 2009]. Similarly, it also has the abilities to degrade p-nitrophenol, MTBE, bisphenol A [Eixarch and Constanti, 2010;Wan et al, 2007;Zhang et al, 2007]. However, there is still no report describing the decolorization of malachite green by A. xylosoxidans .…”

An Achromobacter xylosoxidans MG1 strainisolated from the effluent treatment plant of a textile and dyeing factory from Yunnan Province in China was found capable of decolorizing the malachite green dye at a high efficacy. Strain MG1 reduced 86% malachite green at the concentration of 2,000 mg/l within 1 h, representing a greater ability for decolorizing and a higher tolerance of this compound than all previously reported bacteria. Color removal was optimal at pH 6 and 38°C. Further experimental evidences demonstrated that both cytoplasmic and extracellular biodegradation contributed to the decolorization of malachite green. Nested PCR was employed to identify the candidate genes responsible for malachite green decolorization, and we identified a cytoplasmic triphenylmethane reductase gene with 100% amino acid similarity to the corresponding gene in Citrobacter sp. strain. In contrast to our expectation, the addition of metyrapone had little effect on the cytoplasmic biodegradation, suggesting that cytochrome P450 was not involved in the high-performance reduction. The extracellular biodegradation was likely attributable to the secretion of extracellular proteases and some heat-resistant compounds.

“…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).

“…High R 2 values do not necessarily mean that the decreases of these two pollutant indices follow the same molecular patterns. Different types of molecular mechanisms support the involvement of the different enzyme(s) in the catalysis of biodegradation processes in the same wastewater [19]. OMW, as an agro-industrial wastewater, consists of mixtures of natural substances with variable composition, mainly due to seasonal changes and varied processing conditions.…”
