Most Ka/Ks values of root-exudate-related metabolism genes exhibited little change, except for fumarate hydratase that increased 13-fold in the rhizosphere compared to that in the non-rhizosphere treatment. The Ka/Ks values of less than 50% phenanthrene-degradation-related genes were affected, 30% of which increased and 70% behaved oppositely. in the rhizosphere with those in the bulk soil, but the heterogeneity in the rhizosphere was ignored (Sipila et al. 2008). He et al. (2005) constructed a rhizobox system to divide the rhizosphere with mesh into one mm layers to investigate the spatial changes of pentachlorophenol deg-radation along the rhizosphere gradient.

Feb 18, 2020 Most studies reporting root exudate composition were performed with sterile hydroponic systems to avoid microbial degradation of plant 

The present study was done with the aim of es … 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. 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.

HuR is known to bind the AREs and protect the mRNA from degradation.

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. MTBE soil die-away studies, conducted with both poplar trees and fescue grass, found no significant differences between MTBE concentration in vegetated and unvegetated soils over a two-week attenuation period. 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. The rhizosphere involving the soil pores contains many bacteria and other microorganisms that feed on sloughed-off plant cells, termed rhizodeposition, and the proteins and sugars released by roots, termed root exudates. This symbiosis leads to more complex interactions, influencing plant growth and competition for resources. 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.

Degradation of Diesel Fuel in Rhizosphere Soil. J. Pichtel1,* and P. Liskanen2. 1Natural Resources and Environmental Management. Ball State University.

Degradation of polymers can be supported by the use of plants that are accompanied by microorganisms (Janczak et al., 2014b), in which case it is important to select plant species with a well-developed root system, rapid growth and a large amount of biomass production (Mierek-Adamska et al., 2009; Macci et al., 2013).

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

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.
