  • degradative pathways
  • Several microorganisms able to grow aerobically on dibenzo- p -dioxin or dibenzofuran as a sole carbon source, or to transform these chemicals, have been isolated in the recent years, and the corresponding degradative pathways have been elucidated ( 14 , 20 , 23 , 27 , 31-33 , 36 ). (asm.org)
  • oxidation
  • Oxidation of methane leads to formation of CH4 CHjOH H2C 0 HCOOH CO Serine pathway Ribulose-P pathway Serine pathway Ribulose-P pathway Fig. 17.2 Aerobic pathways of methane oxidation (after Rojo 2009) methanol which is subsequently transformed to formaldehyde and then to formic acid (Fig. 17.2).

  • Second and third [per]oxygenation was also observed and resulted in the formation of further hydroxylation and following [per]oxidation products: hydroquinone and p -benzoquinone, catechol and o -benzoquinone as well as 1,2,4-trihydroxybenzene and hydroxy- p -benzoquinone, respectively.

  • In the presence of PcpD, TCBQ formed by pentachlorophenol hydroxylase (PcpB) is sequestered until it is reduced to the less toxic tetrachlorohydroquinone, protecting the bacterium from the toxic effects of TCBQ and maintaining flux through the pathway. (pnas.org)
  • Sphingomonas
  • This finding is consistent with the catabolic versatility of members of the genus Sphingomonas , which is becoming increasingly evident, and may indicate a less well evolved and regulated but more dynamic genetic organization in this organism than is the case for better-studied pathways in organisms such as Pseudomonas species.

  • microorganisms
  • These limited studies have clearly revealed that degradation of oxygenated and non-oxygenated hydrocarbons by halophilic and halotolerant microorganisms occur by pathways similar to those found in non-halophiles. (frontiersin.org)
  • Under aerobic conditions, side-chain oxygenation of styrene seems to be the favored mechanism, since most microorganisms investigated in that respect were found to follow this degradation pathway (Hartmans et al. (drdarrinlew.us)
  • enzymatic
  • Three mechanisms for the transformation of RDX have been proposed two-electron reduction, single-electron reduction denitration, and direct enzymatic cleavage. (drdarrinlew.us)
  • selective
  • 1H NMR spectral data of polycaprolactone (PCL) obtained showed that the poly-merization mechanism is in agreement with the coordination-in-sertion mechanism and the selective cleavage of the acyl-oxygen bond of CL. (worldwidescience.org)
  • toxicity
  • The toxicity of such intermediates can pose a significant challenge to the evolution of efficient pathways for the degradation of anthropogenic compounds ( 1 ). (pnas.org)
  • Identical
  • To assess the effects of macromolecular crowding on unfolding of an oligomeric protein, we here tested the effects of the synthetic crowding agent Ficoll 70 on human cpn10 (GroES in E. coli), a heptameric protein consisting of seven identical β-barrel subunits assembling into a ring.
