The first compilation of research on microbial degradation of contaminants in the rhizosphere. Discusses the interactions between microorganisms, plants, and chemicals in the rhizosphere. Examines the degradation of industrial chemicals, including polycyclic aromatic hydrocarbons, pentachlorophenol, and trichloroethylene, as well as the degradation of pesticides in the rhizosphere.

Rhizosphere degradation

Keywords: crude oil pollution; bacterial community; soil rhizosphere. 1. Introduction. Degradation is facilitated through a rhizosphere effect where plants exude organic compounds through their roots and thereby increase the density and activity Results: 23 indigenous oil-degrading bacterial strains were isolated from the wild oat rhizosphere, grown in severely oil contaminated soil in Khuzestan. Based on Jan 26, 2016 In this paper, a new mathematical modeling of rhizosphere microbial degradation with impulsive diffusion is proposed. By using the Floquet Jul 24, 2015 Hydrocarbon degradation was measured by GC–MS (Gas-chromatography the rhizosphere to support an active soil microbial population.

Leaching, plant uptake, abiotic degradation, mineralization to CO 2 , and irreversible sorption were shown to be insignificant in the overall mass balance of the target compounds. Abstract Rhizosphere soil has a more diverse and active microbial community compared to nonvegetated soil. Con-sequently, the rhizosphere pyrene degrader population (PDP) and pyrene degradation may be enhanced compared to nonvegetated bulk soil (NVB). The objectives of this growthchamber study were to compare (1) Bermuda grass The rhizosphere soil had an order of magnitude higher microbial numbers (4.2 × 10 5 ) compared with the edaphosphere soil (3.5 × 10 4 .) A degradation experiment that did not incorporate vegetation was carried out by using sterile control soil, Kochia sp.

in the rhizosphere with those in the bulk soil, but the heterogeneity in the rhizosphere was ignored (Sipila et al. 2008). He et al. (2005) constructed a rhizobox system to divide the rhizosphere with mesh into one mm layers to investigate the spatial changes of pentachlorophenol deg-radation along the rhizosphere gradient. The degradation

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.

After 60 days, 69-85% and 59-80% of spiked pyrene disappeared from the rhizosphere and non-rhizosphere soils, respectively. The removal percentage decreased with increasing pyrene concentration. However, the average removal of pyrene in the rhizosphere soil was 6% higher than that in the non-rhizosphere soil. The rhizosphere is the narrow region of soil or substrate that is directly influenced by root secretions and associated soil microorganisms known as the root microbiome. The rhizosphere involving the soil pores contains many bacteria and other microorganisms that feed on sloughed-off plant cells, termed rhizodeposition, and the proteins and sugars released by roots, termed root exudates. This symbiosis leads to more complex interactions, influencing plant growth and competition Abstract Methyl tertiary butyl ether (MTBE) is a gasoline additive associated with ground water pollution at gas station sites. Previous research on poplar trees in hydroponic systems suggests that phytovolatilization is an effective mechanism for phytoremediation of MTBE (Rubin and Ramaswami, 2001), but the potential for microbial degradation of MTBE in the rhizosphere of trees had not been Rhizosphere interactions stimulate contaminant degradation by enhancing soil physical, chemical, and biological properties (adapted from Reynolds et al., 1999) Short-Term Rhizosphere Effect on Available Carbon Sources, Phenanthrene Degradation, and Active Microbiome in an Aged-Contaminated Industrial Soil François Thomas 1,2 † and Aurélie Cébron 1,2 * 1 CNRS, LIEC UMR7360, Faculté des Sciences et Technologies, Vandoeuvre-lés-Nancy, France Rhizoremediation is the use of plant-microbe interaction for the enhanced degradation of contaminants.
