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
role and characterization of a cyanide induced 3-cyanoalanine nitrilase in the cyanide assimilating bacterium pseudomonas pseudoalcaligenes cect 5344.	pseudomonas pseudoalcaligenes cect 5344 is a bacterium able to assimilate cyanide as the sole nitrogen source. under this growth conditions, a 3-cyanoalanine nitrilase enzymatic activity was induced. this activity was coded by nit4, one of the four nitrilases detected in the genome of this bacterium, and its expression in e. coli enabled the recombinant strain to fully assimilate 3-cyanoalanine. p. pseudoalcaligenes cect 5344 showed a weak growth level with 3-cyanoalanine as n-source, unless kcn ...	2017	28235872
