In this case, called cometabolism
, the microorganism derives no direct benefit.
of a wide range of substrates may present a competitive advantage, especially under nutrient-limiting conditions (Egli, 1995).
In microbial consortia, cometabolism
turns the mineralization of these compounds more efficient .
Duffy et al., Progress and Challenges in Developing Metabolic Footprints from Diet in Human Gut Microbial Cometabolism
(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.
Addition of glucose enhanced atrazine mineralization due to 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
. Though plant exposure to both gaseous and solid phase PAHs in ambient air was not determined in this study, the process of accumulation is reported to be affected by several abiotic and biotic factors including vapor-particulate partitioning in the atmosphere, ambient temperature, octanol-air partitioning coefficients, leaf surface area and lipid concentration in the plant tissues (Slaski et al., 2000).
