The cometabolism of a wide range of substrates may present a competitive advantage, especially under nutrient-limiting conditions (Egli, 1995).
2006) establish that the plants render an important function on the phytoremediation of organic compounds like the hydrocarbons because i) The rhizosphere improves the properties of the soil through the injection of air and the introduction of nutrients that encourage microbial diversity, ii) the interaction between the plant and the microorganisms promotes the cometabolism of the contaminants that forces the activation of several metabolic options, and iii) the transportation of water to the superior areas of the plant works in favor of the degradation or immobilization of the contaminant in order to produce a degradation in the interior and exterior of the plant.
Cometabolism of Cr (VI) by Shewanella oneidensis MR-1 produces cell-associated reduced chromium and inhibits growth.
Also, the phyllosphere is a harsh environment that does not favor enhanced cooperative interactions between microbial species that could degrade the pollutant through cometabolism.
Phenol and toluene-degrading microbial populations from an aquifer in which successful trichloroethene cometabolism occurred.
Regarding the microbiota performance into the mixture of PAHs (Figure 1), one additional specie was detected at week-2 (band 1), remaining on all period and suggesting ability to survive in several complex PAHs under cometabolism, probably growing by using intermediate metabolites as carbon source produced by other microorganisms when degrading PAHs.
In the presence of phenol as a growth substrate, 2-cp and 4-cp could be transformed through cometabolism.
Gilbert worked in Professor David Crowley's lab with funding from the TSRTP, where they searched for a nontoxic chemical that could induce cometabolism of PCBs, since it is known that some bacteria can biodegrade PCB only in conjunction with another substance.
