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.

β-Hexachlorocyclohexane was also degraded, but slowly. 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. Rhizosphere bioremediation or rhizodegradation is the enhanced biodegradation of recalcitrant organic pollutants by root‐associated bacteria and fungi under the influence of select plant species.

1b). The degradation of root exudates by the rhizosphere microbiome in +DR was greater than for −DR (P < 0.01).

Provision of SA led to a lower level of IPU residues in rhizosphere soil compared to IPU treatment alone. Root exudation of tartaric acid, malic acid, and oxalic acids was enhanced in rhizosphere soil with SA-treated wheat.

Microbial communities in the rhizosphere enhance plants’ health and promote nutrient turnover and cycling in the soil.

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. 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.

J. Pichtel1,* and P. Liskanen2. 1Natural Resources and Environmental Management. Ball State University. In several studies, rhizodegradation is a specific type of phyto-remediation that involves both plants and their associated rhizosphere microbes; this interaction was The rhizosphere microbe can play a key role in decomposing organic matter through releasing inorganic nutrient available to wetland plant. The degradation Rhizoremediation is a process where microorganisms degrade soil contaminants in the rhizosphere. Soil pollutants that are remediated by this method are Rhizosphere interactions stimulate contaminant degradation by enhancing soil physical, chemical, and biological properties (adapted from Reynolds et al., 1999 ).
