Because rhizosphere microbial communities have enhanced populations and activity compared to surrounding soils, and since specific microbial populations are associated with particular plant communities, manipulation of the plant community offers a way to enhance microbial degradation of RDX with a minimum of expense and maintenance. This study investigated the herbicide isoproturon (IPU) residues in soil, where wheat was cultivated and sprayed with salicylic acid (SA). Provision of SA led to a lower level of IPU residues in rhizosphere soil compared to IPU treatment alone. Root exudation of tartaric acid, malic acid, and oxalic acids was enhanced in rhizosphere soil with SA-treated wheat.

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. Dec 24, 2013 resistant to microbial degradation because of it's high mo- lecular weight and polluted.

720-614-5197 mikroorganismer utformade för rhizoremediation inducerar förändringar på nativa bakterier i rhizosphere men inte i den omgivande jorden. The concept: Microorganisms (biomass) grow in the aeration tank and degrade organic matter while consuming oxygen. Floc formation is essential for settling. Three experiments were conducted at different levels of aggregation to examine possible degradation of MTBE by rhizosphere microorganisms that had been acclimated to low levels of MTBE for 6 weeks.

Combined rhizospheric action of M. maximus and fungi speed up lindane degradation rate, initially detected lindane concentration of 45 mg/kg was reduced to 11.26, 9.34 and 11.23 mg/kg in 20, 30 and 40% treatments respectively making 79.76, 85.93 and 88.67% degradation efficiencies. Studies of polycyclic aromatic hydrocarbon (PAH)-degrading bacteria and plant root exudate enzymes from contaminated rhizospheres suggest that pollutant rhizodegradation involves the joint work of bacteria and plants. Rhizodegradation, also known as phyto-stimulation, is the degradation of contaminants in the rhizosphere (area of soil surrounding the roots of the plants) by means of microbial activity which is enhanced by the presence of plant roots. 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. The ability of rhizosphere of four plant species to promote the degradation of charcoal-fixed atrazine and simazine in cement blocks of a long-term contaminated soil when mixed with a normal soil at 1:1 ratio was tested. Of the four selected plants viz., rye grass (Lolium perenne), tall fescue (Fest … Promotion of pyrene degradation in rhizosphere of alfalfa (Medicago sativa L.). Fan S(1), Li P, Gong Z, Ren W, He N.

PY - 2008/5/1. Y1 - 2008/5/1 There were significant (p < 0.05) differences in microbial degradation dynamics of BSM in the rhizosphere soils among three kinds of riparian plants. A. calamus displayed a significantly (p < 0.05) higher degradation efficiency of BSM in the rhizosphere soils, followed by Z. aquatica and P. australis . 2018-01-12 · The transcripts of two other pathways were also significantly more abundant in the rhizosphere of S. miyabeana growing in contaminated soils: ko00362 “Benzoate degradation” and ko00071 2021-02-08 · Soil microbes perform important functions in nitrogen and carbon cycling in the biosphere. Microbial communities in the rhizosphere enhance plants’ health and promote nutrient turnover and cycling in the soil. In this study, we evaluated the effects of soil fertilization with organic and inorganic fertilizers on the abundances and distribution of carbon and nitrogen cycling genes within the 2014-11-10 · The maize rhizosphere had significantly enriched genes involved in carbon fixation and degradation (especially for hemicelluloses, aromatics and lignin), nitrogen fixation, ammonification, denitrification, polyphosphate biosynthesis and degradation, sulfur reduction and oxidation. Degradation of Diesel Fuel in Rhizosphere Soil.
