Results: 23 indigenous oil-degrading bacterial strains were isolated from the wild oat rhizosphere, grown in severely oil contaminated soil in Khuzestan. Based on

Rhizosphere bioremediation of pyrethroid pesticides will offer an attractive and potentially inexpensive approach for remediation of contaminated soil. The present study was done with the aim of es … 2011-06-15 · Rhizodegradation is the breakdown of organic contaminants in soil through microbial activity which is enhanced by the presence of the root zone. Thus, rhizodegradation of pollutants in soil becomes promising for the areas when plants can grow. 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 … 2017-08-31 · Synergistic rhizosphere degradation of lindane using fungi and M. maximus root, follows the following three proposed pathways: The dechlorination of γ-HCH (lindane) into (γ-Hexachlorocyclohexane), till (2,5-DCB), Chlorobenzene and benzene ( Fig 4 The dechlorination of γ-HCH (lindane) into Hypotheses that support improved degradation within the rhizosphere compared to nonvegetated soils include (i) increase in microbial density, diversity and/or metabolic activity, (ii) catabolic Abstract. A suspension of soil from the rhizosphere of sugarcane plants grown from sugarcane setts treated with a commercial formulation of hexachlorocyclohexane effected exceptionally rapid degradation of α- and γ-isomers of hexachlorocyclohexane in a mineral salts medium under aerobic conditions. β-Hexachlorocyclohexane was also degraded, but slowly.

Interactions between plant and rhizosphere microbial communities in a metalliferous Consequences include permafrost thaw, increased microbial degradation of soil vicinity and thereby accelerate soil CO2 emissions ( rhizosphere priming ). (2013).

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. rhizosphere soil, and edaphosphere soil spiked with a mixture of atrazine, metolachlor, and trifluralin at levels typical of point-source The degradation of allelopathic compounds by bacteria associated with the plants would limit their effectiveness, but little is known about the extent of biodegradation or the bacteria involved. Screening of tissues and rhizosphere of peanut (Arachis hypogaea) plants revealed substantial enrichment of bacteria able to grow on resveratrol and pterostilbene, the most common stilbenes produced by Compared with the rhizosphere soil of the pure plant communities, the mixed community of P. australis and A. calamus displayed a significantly greater degradation rate of butachlor in the rhizosphere soil. 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.

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 (Festuca arundinacae), Pennisetum (Pennisetum clandestinum) and a spring onion (Allium sp.) used in Enhanced biological degradation in the rhizosphere appears to be a mechanism of dissipation. 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.

6.20.2.1.7 Rhizosphere bioremediation: Microbial degradation in the rhizosphere Rhizosphere bioremediation refers to biodegradation of pollutants by microorganisms in the root zone. Plants are known to increase both microbial numbers and metabolism in soil, resulting in increased biodegradation activity. 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.
