In the rhizosphere, the NPATZs and ATZ were found to be initially degraded by Mycobacterium and Pseudomonas bacteria. As the exposure time increased, more bacterial consortia became involved in NPATZ degradation than in ATZ degradation, especially in metabolizing N -isopropylammelide to carboxybiuret catalyzed by the genes atzC and atzD.

Degradation of atrazine and simazine was also studied in the mineral salt medium inoculated with suspension of non-rhizosphere and rhizosphere soil from herbicide-contaminated soil unplanted and planted with P. clandestinum. Atrazine (300 μg) or simazine (50 μg) was added to 50-ml sterilized Erlenmeyer flasks in 1 ml of acetone. Among plant species, grasses offer some advantages for evaluating the rhizosphere effect on organic pollutant degradation and bacterial communities. They possess a fibrous root system allowing intensive penetration of the soil together with large surface area ( Aprill and Sims, 1990 ; Dzantor et al., 2000 ) and exude high quantities of soluble Moreover, we observed a lower abundance of genes coding for enzymes which trigger the degradation of aromatic compounds in rhizosphere of soils affected by replant disease, which is probably connected with higher concentration of phenolic compounds, generally associated with disease progression.

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.

Rhizosphere degradation of PAHs by symbiotic and plant-associated bacteria is controlled by the macropartner through its root exudates. Plant root exudates contain a variety of low- and high-molecular-weight organic substances that are nutrients and signaling molecules affecting the rhizosphere microflora.

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.

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.
