Jul 1, 2010 · The microbial degradation of phenol by pure cultures Bacillus cereus MTCC 9817 strain AKG1 and B. cereus MTCC 9818 strain AKG2 is studied in batch mode for several initial concentrations of phenol in the range of 100–2000 mg/L with an interval of 100 mg/L. Degradation pathways are investigated at initial phenol concentrations of 100, 500 ...

Sep 1, 2016 · During its degradation, phenol is first monohydroxylated by phenol hydroxylase (PH) at the ortho position to the pre-existing hydroxyl group to generate catechol, which is then catalysed by either catechol 1, 2-dioxygenase (C12O), which initiates the ortho-pathway leading to formation of succinic acid and acetyl-CoA (Pandeeti and Siddavattam ...

He and Wiegel (1995) show that 4-hydroxybenzoate decarboxylase catalyzes the conversion of phenol to 4-hydroxybenzoate via anaerobic carboxylation in a Clostridium species. The following is a text-format anaerobic phenol degradation pathway map. Organisms which can initiate the pathway are given, but other organisms may also carry out later steps.

Biodegradation by microorganisms offers unique opportunities to destroy or render phenolic compounds. A bacterium, PU1, identified as Pseudomonas fluorescens PU1, was investigated for its ability to grow on and degrade phenols as sole carbon sources in …

Jul 12, 2022 · Using RetroPath RL 27, we analyzed tentative metabolic pathways for the phenolic compounds present in Phenol-Explorer 19. We provide details as to the reactions, metabolites and species...

Jan 15, 2021 · A broad comparative genome analysis of phenol metabolism pathway based on metabolic gene copy number analysis is essential for understanding of the phenol degradation mechanism and will provide insights into the potential of metabolic engineering applications.

Jul 13, 2016 · The present work is the first known report of phenol degradation via the meta-pathway by a member of the genus Acinetobacter and describes purification and characterization of a new low molecular weight phenol hydroxylase form Acinetobacter sp. strain AQ5NOL 1.

In this study, we have presented the pathway and degradation kinetics of phenol by Pseudomonas and Bacillus species. Bacterial strains were grown aerobically at 35 °C under shake flask conditions.

May 2, 2007 · Many aerobic phenol-degrading microorganisms have been isolated and the pathways for the aerobic degradation of phenol are now firmly established. The first steps include oxygenation of phenol by phenol hydroxylase enzymes to form catechol, followed by ring cleavage adjacent to or in between the two hydroxyl groups of catechol.

Jun 1, 2020 · In this paper, we provide an extended kinetic study of phenol biodegradation realised in an anaerobic sequencing batch reactor (SBR) operated with a microbial consortium. The process was investigated with and without glucose as co-substrate.
