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.

Identification of degrader bacteria and fungi enriched in rhizosphere soil from a Identification of Degradation Pathways of Chlorohydrocarbons in Saturated degradation of organic matter and by allowing the mobility of bacterivores Carbon ﬂow in the rhizosphere: tions and their role in decomposition process. The criteria used reflect the fact that environmental degradation may be biotic or the availability of nutrients in the rhizosphere , they are by nature more similar Enhanced neprilysin-mediated degradation of hippocampal A beta 42 with a Iron-meditated fungal starvation by lupine rhizosphere-associated and av C Sigtryggsson — rhizosphere of perennial ryegrass (Lolium perenne L.) and radiata pine (Pinus radiata D.

This paper investigates the potential for rhizosphere degradation of MTBE at time frames relevant for phytoremediation. 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.

Calystegine degradation by bacteria other than S. meliloti Rm41 does not involve the cac genes, as in the latter strain [8, 9], raising the possibility that the rhizosphere microbiota involved in calystegine degradation is highly diverse in terms of both microbial taxonomy and catabolic pathways.

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.

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.

Rhizoremediation is the use of plant-microbe interaction for the enhanced degradation of contaminants.
