“…Yoon and Pyo (2003) reported the development and characterization of a strain highly effective in degrading phenol and resistant to the effect of heavy metals ions. In order to restricted or minimized the effect of heavy metals on the hydrocarbon degradation capability of microorganisms the following actions are recommended (Riis et al, 2002;Malakul et al, 1998: Babich et al, 1977.  Application of phosphate or sulfate compounds at the contaminated site to induce the precipitation of heavy metal ions.…”

“…al., 1985;Baldrian, 2003) and their addition in soil has been known to inhibit soil respiration, nitrogen mineralization and nitrification (Bååth, 1989;McGrath, 1994). Heavy metals have been implicated in the reduction of degradation of vegetable materials (Bååth, 1989) and can potentially limit the biodegradation of organic contaminants in the environment (Sokhn et al, 2001;Riis et al, 2002;Atagana, 2006). One of the serious problems of contamination biotechnologists is the problem of co-contamination of PAHs and heavy metals, which is a common occurrence in sites of wood treatment plants using creosote and chromated copper arsenate (CCA) and those contaminated with petroleum products and pesticides (Baker and Bryson, 2002).…”

The study investigated the degradation of the polycyclic aromatic hydrocarbons (PAH) benzo(a)anthracene, benzo(a) fluoranthene, benzo(a) pyrene, chrysene and phenanthrene in a soil that was sterilized and inoculated with the nonligninolytic fungi, Fusarium flocciferum and Trichoderma spp. and the ligninolytic fungi, Trametes versicolor and Pleurotus ostreatus in the presence of cadmium (Cd) and nickel (Ni) during a ten week incubation period. The soil pH was initially 5.3 and after amendment increased to 7.0. The fungi degraded the tested PAHs between 21 and 93% by the end of the tenth week. The fungi degraded the less-soluble PAHs containing five or six aromatic rings more slowly than those containing fewer aromatic rings. Although the presence of cadmium and nickel in the soil affected the activity of the enzymes produced by the fungi, no significant decrease in PAH degradation was found in the contaminated soil containing 50 or 100 mg kg -1 of Cd and Ni. However, at 300 and 500 mg kg -1 , degradation of the PAHs by the fungi was impaired and the severity of the impairments increased with the increase in the concentrations of Cd and Ni. This was probably due to the lack of the activities of some enzymes such as Mn-dependent peroxidase, which could have resulted from the poor colonization of the fungi at these concentrations.

“…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.
