| analysis of substrate range of biphenyl-catabolic enzymes. | by using transposon mutants it was demonstrated that biphenyl catabolic bph enzymes have very relaxed substrate specificities for a variety of aromatic compounds. however, the substrate ranges of the bph enzymes of two strains used were different from each other. pseudomonas pseudoalcaligenes kf707 bph enzymes converted biphenyls substituted with halogen, hydroxyl, methyl, and nitro groups, and biphenylrelated compounds such as biphenylmethane, dibenzyl, diphenylether, diphenylamine, and benzala ... | 1996 | 27299397 |
| efficient biodegradation of acephate by pseudomonas pseudoalcaligenes ps-5 in the presence and absence of heavy metal ions [cu(ii) and fe(iii)], and humic acid. | the present study was intended to investigate the biodegradation of acephate in aqueous media in the presence and in the absence of metal ions [fe(iii) and cu(ii)], and humic acid (ha). biodegradations were performed using pseudomonas pseudoalcaligenes ps-5 (ps-5) isolated from the heavy metal polluted site. biodegradations were monitored by uv-visible, ftir, and electron spray ionization-mass spectrometry (esi-ms) analyses. esi-ms analysis revealed that ps-5 degraded acephate to two metabolites ... | 2017 | 28744429 |
| biphenyl modulates the expression and function of respiratory oxidases in the polychlorinated-biphenyls degrader pseudomonas pseudoalcaligenes kf707. | pseudomonas pseudoalcaligenes kf707 is a soil bacterium which is known for its capacity to aerobically degrade harmful organic compounds such as polychlorinated biphenyls (pcbs) using biphenyl as co-metabolite. here we provide the first genetic and functional analysis of the kf707 respiratory terminal oxidases in cells grown with two different carbon sources: glucose and biphenyl. we identified five terminal oxidases in kf707: two c(c)aa3 type oxidases (caa3 and ccaa3), two cbb3 type oxidases (c ... | 2017 | 28713350 |
