P. alcaligenes

Pseudomonas stutzeri, P. alcaligenes, and P. putida strains were isolated and proven to remove DBT, benzothiophene, thioxanthene, and thianthrene by decomposition into water-soluble substances [120],... 

Evaluation of P. nitroreducens with quinoline as the sole source of nitrogen showed a reduction of the total nitrogen content by 85%. The partial sequence of the 16S-rRNA gene of this Gram-negative, rod-shaped bacterium was determined and shown to be close to P. alcaligenes and P. stutzeri. 

The characteristics of an extracellular mcl-PHA depolymerase purified from the marine isolate Pseudomonas luteola M13-4 have been reported by Rhee et al. (2006). This enzyme is similar to Pseudomonas alcaligenes LB 19 (Kim et al. 2002) but is different from poly(HB-co-HV) (PHBV) depolymerase of Xanthomonas sp JS02 (Kim et al. 2000a, b, c) the molecular mass is 28 kDa, the isoelectric point is 6.0 with a reactivity optimum at pH 10 and 40°C. Serine residues seem to play an important role in the hydrolysis reaction by analogy with P. alcaligenes LB 19. PHO has been totally degraded polyhydroxyhexanoate (PHH) and a copolymer of (PHB-co-60%HV) have been partially hydrolyzed.

Lipases from C. antarctica and P. cepacia showed higher enantioselectivity in the two ionic liquids l-ethyl-3-methylimidazolium tetrafluoroborate and l-butyl-3-methylimidazolium hexafluoroborate than in THE and toluene, in the kinetic resolution of several secondary alcohols [49]. Similarly, with lipases from Pseudomonas species and Alcaligenes species, increased enantioselectivity was observed in the resolution of 1 -phenylethanol in several ionic liquids as compared to methyl tert-butyl ether [50]. Another study has demonstrated that lipase from Candida rugosa is at least 100% more selective in l-butyl-3-methylimidazolium hexafluoroborate and l-octyl-3-nonylimidazolium hexafluorophosphate than in n-hexane, in the resolution of racemic 2-chloro-propanoic acid [51].

Ralstonia eutropha (Alcaligenes eutrophus) strain NH9 is able to degrade 3-chlorobenzene by the modified ortho pathway. The cbnA gene that encodes 3-chlorocatechol-l, 2-dioxygenase was introduced into rice plants (Oryza sativa -p.japonicd) under the control of a virus 35S promoter. 3-Chlorocatechol induced dioxygenase activity in the callus of the plants, and leaf tissues oxidized 3-chlorocatechol with the production of 2-chloromuconate...

R. eutropha, formerly known as Alcaligenes eutrophus, has been used for the commercial production of P(3HB-co-3HV) [72]. This bacterium grows well in a relatively inexpensive minimal medium and accumulates a large amount of P(3HB) under the unbalanced growth condition. In R. eutropha, acetyl-CoA is converted to P(3HB) by three enzymes (genes) /J-ketothiolase (phaA), aceto-acetyl-CoA reductase (phaB), and PHA synthase (phaC) [6].
