Oct 8, 2009 Furthermore, little is known about soil microbial populations responsible for PCB degradation in the rhizosphere of plants or how they are  We collected soil samples from a former chlorinated- solvent disposal site and compared microbial degradation of trichloroethylene (TCE) in rhizosphere soils  Numerous bacterial species were reported to degrade variety of PAHs and most of The first study towards degradation of compounds in the rhizosphere was  Feb 25, 2020 synergistic degradation by S. salsa and bacteria. 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.

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.

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.

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.

John Kempf and Dr. Jill Clapperton delve into the science of the rhizosphere.

Impact of microbial/plant interactions on the transformation of

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. 2011-01-31 · Rhizodegradation. 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.

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.
