“…However, both metals at low concentration significantly reduced the growth of sensitive strain (Siunova et al, 2007). Ten-fold increase of both metals concentration caused slightly increased a lag phase in the case of resistant variant PhCN whereas completely inhibited the growth of the sensitive strain PhCN1.…”

“…Cadmium at concentration of 10 µM in MSM medium with phenol and ammonium as a sole source of carbon and nitrogen, respectively, did not affect the growth rate of PhCN, whereas, the growth of sensitive strains was significantly reduced comparing with that of the cadmium free medium (Figure 2A). Phenol consumption by sensitive strain PhCN1, was significantly reduced compared to that of the free-cadmium MSM ( Figure 3A) (Amor et al, 2001;Siunova et al, 2007). However, the addition of cadmium at a concentration of 10 µM did not change the rate of phenol consumption by resistant strain PhCN as compared to that of the free-cadmium MSM ( Figure 3A) (Siunova et al, 2007).…”

“…The use of these microorganisms may face various problems, including poor survival, substrate accessibility (Lin et al, 2006), or the presence of inhibitory compounds. Heavy metals are known to be powerful inhibitors of biodegradation activities (Said and Lewis, 1991;Roane and Pepper, 1997;Roane et al, 2001;Amor et al, 2001;Hong et al, 2007;Silva et al, 2007), thus, their presence may impair the biodegradation of aromatic compounds in polluted sites (Springael et al, 1993;Kuo and Genther, 1996;Benka-Coker and Ekundayo, 1998;White and Knowles, 2003;Roane et al, 2001;Sokhn et al, 2001;Riis et al, 2002;Lin et al, 2006;Silva et al, 2007;Siunova et al, 2007). Simultaneous contamination by heavy metals and organic compounds may also occur and such contamination cases had been reported before at industrial areas (Al-Saleh and Obuekwe, 2005).…”

Natural combination of genetic systems for degradation of phenol and resistance to heavy metals in phenol and cyanide assimilating bacteria

Combination of genetic systems of degradation of xenobiotic compound and heavy metal resistance is one of the approaches to the creation of polyfunctional strains for bioremediation of soil after co-contamination with organic pollutants and heavy metals. A bacterial strain Pseudomonas putida PhCN (pPhCN1, pPhCN2) has been obtained. This bacterium contains two plasmids, a 120-kb catabolic plasmid that encodes for breakdown of phenol (pPhCN1) and pPhCN2 plasmid that codes for cadmium and copper resistant. Cyanide assimilation by this bacterium is encoded by chromosomal genes. The inhibitory effect of cadmium (Cd ) on the degradation of phenol by P. putida strains PhCN and PhCN1 (contained pPhCN1) were investigated in the presence of phenol and cyanide as a sole carbon and nitrogen source, respectively. The resistant strain PhCN showed high ability to degrade phenol and cyanide in presence of Cd 2+ or Cu 2+ as compared to the sensitive strain PhCN1. In addition, Cd 2+ or Cu 2+ was also found to exert a strong inhibitory effect on the C23O dioxygenase enzyme activity in the presence of cyanide as a nitrogen source. However, the presence of heavy metal resistance plasmid alleviated the inhibitory effect of metals on the enzyme activity in resistant strain.

Comamonas sp. UVS was able to decolorize Reactive Blue HERD (RBHERD) dye (50 mg L −1 ) within 6 h under static condition. The maximum dye concentration degraded was 1,200 mg L −1 within 210 h. A numerical simulation with the model gives an optimal value of 35.71±0.696 mg dye g −1 cell h −1 for maximum rate (V max ) and 112.35±0.34 mg L −1 for the Michaelis constant (K m ). Comamonas sp. UVS has capability of decolorization of RBHERD in the presence of Mg 2+ , Ca 2+ , Cd 2+ , and Zn 2+ , whereas decolorization was completely inhibited by Cu 2+ . Metal ions also affected the levels of biotransformation enzymes during decolorization of RBHERD. Comamonas sp. UVS was also able to decolorize textile effluent with significant reduction in COD.The biodegradation of RBHERD dye was monitored by UV-vis spectroscopy, FTIR spectroscopy, and HPLC.
