• Dienelactone hydrolases play a crucial role in chlorocatechol degradation via the modified ortho cleavage pathway. (inrae.fr)
  • The data obtained did not allow us to detect strains decomposing benzoate via the pathway of meta -cleavage, since there was no yellow coloration of the medium, characteristic of 2-hydroxymuconic semialdehyde formed as a result of meta -cleavage of catechol, a product of benzoate biodegradation. (sciforum.net)
  • The downstream transformation of BA involved a meta -cleavage pathway, although its genetic organization and function was not revealed and the overall network of genes driving the full metabolic pathway of OPP is still not known. (nature.com)
  • In this divergent mode, a metal-dependent dioxygenase channels these dihydroxylated intermediates into one of the two possible pathways: the meta -cleavage pathway or the ortho -cleavage pathway [ 7 - 9 ] (Fig. 1 ). (biomedcentral.com)
  • 2021. Differential roles of three different upper pathway meta ring cleavage product hydrolases in the degradation of dibenzo-p-dioxin and dibenzofuran by Sphingomonas wittichii strain RW1. (nih.gov)
  • 2021. Separate upper pathway ring cleavage dioxygenases are required for growth of Sphingomonas wittichii strain RW1 on dibenzofuran and dibenzo-p-dioxin. (nih.gov)
  • Based on the complexity of the degradation pathways, the phenomenon of biodegradation is categorized into two types: convergent and divergent modes of degradation (Fig. 1 ). (biomedcentral.com)
  • ß- and δ-isomers of HCH are highly toxic, persistent, and recalcitrant to biodegradation, slow and incomplete degradation of ß- and δ- isomers have been reported in a few strains. (bvsalud.org)
  • Herein, we found that intracellular enzymes were the major contributors to E2 biodegradation by strain ES2-1. (bvsalud.org)
  • Despite the relatively simple structure of the benzoate molecule, the biodegradation of this compound presupposes the presence of specialized biodegradation pathways and genes. (sciforum.net)
  • It is important to emphasize that the isolation of soil microorganisms on a mineral medium with benzoate made it possible to quickly assess the presence of one of two biodegradative pathways - ortho - or meta -cleavage of catechol. (sciforum.net)
  • They play a key role in the metabolism of organic compounds by increasing their reactivity or water solubility or bringing about cleavage of the aromatic ring. (biomedcentral.com)
  • In the convergent mode, structurally diverse aromatic compounds are converted to one of a few aromatic ring cleavage substrates such as catechol, gent sate, protocatechuate and their derivatives [ 5 ]. (biomedcentral.com)
  • 4-OH-E1 meta-cleavage was catalyzed by a dioxygenase encoded by IM701_20340 or IM701_21000 or IM701_09625. (bvsalud.org)
  • Advanced oxidation processes (APOs) of aromatic compounds, particularly of phenol, yield several benzene derivatives, such as hydroquinone, catechol, and resorcinol, as intermediate metabolites of its transformation. (hindawi.com)
