This symbiosis leads to more complex interactions, influencing plant growth and competition for resources. Finally, rhizosphere microbes tested in aerated bioreactors were found to be thriving and metabolizing root materials, but did not show measurable degradation of MTBE. In all tests, the MTBE degradation product, Tert Butyl Alcohol (TBA), was not detected. Degradation of polymers can be supported by the use of plants that are accompanied by microorganisms (Janczak et al., 2014b), in which case it is important to select plant species with a well-developed root system, rapid growth and a large amount of biomass production (Mierek-Adamska et al., 2009; Macci et al., 2013). 18.104.22.168.7 Rhizosphere bioremediation: Microbial degradation in the rhizosphere Rhizosphere bioremediation refers to biodegradation of pollutants by microorganisms in the root zone.

By exuding more carbon into the rhizosphere, exploitative species attract more taxa on root tissues and RAS. They also stimulate more taxa involved in SOM degradation by “priming effect” mechanism (Fontaine et al., 2003). Most Ka/Ks values of root-exudate-related metabolism genes exhibited little change, except for fumarate hydratase that increased 13-fold in the rhizosphere compared to that in the non-rhizosphere treatment. The Ka/Ks values of less than 50% phenanthrene-degradation-related genes were affected, 30% of which increased and 70% behaved oppositely. in the rhizosphere with those in the bulk soil, but the heterogeneity in the rhizosphere was ignored (Sipila et al. 2008).

Phytoremediation has been demonstrated to enhance the degradation of PAHs, but the mechanisms of dissipation have not been identified. The degradation of pyrene and anthracene was investigated in a laboratory study in which soil was removed from the rhizosphere of a long-term stand of alfalfa and compared to degradation in non-rhizosphere and sterile soil.

In several studies, rhizodegradation is a specific type of phyto-remediation that involves both plants and their associated rhizosphere microbes; this interaction was The rhizosphere microbe can play a key role in decomposing organic matter through releasing inorganic nutrient available to wetland plant. The degradation Rhizoremediation is a process where microorganisms degrade soil contaminants in the rhizosphere. Soil pollutants that are remediated by this method are Rhizosphere interactions stimulate contaminant degradation by enhancing soil physical, chemical, and biological properties (adapted from Reynolds et al., 1999 ). Oct 8, 2009 Furthermore, little is known about soil microbial populations responsible for PCB degradation in the rhizosphere of plants or how they are We collected soil samples from a former chlorinated- solvent disposal site and compared microbial degradation of trichloroethylene (TCE) in rhizosphere soils Numerous bacterial species were reported to degrade variety of PAHs and most of The first study towards degradation of compounds in the rhizosphere was Feb 25, 2020 synergistic degradation by S. salsa and bacteria.
