Biodegradation of phenol and cresol isomer mixtures by Arthrobacter
TLDR
The Arthrobacter species can degrade phenol, o-cresol and p-Cresol much faster than other microbes which are reported to degrade toxic compounds.Abstract:
The Arthrobacter species can degrade phenol, o-cresol and p-cresol much faster (as reflected in high specific growth rates) than other microbes which are reported to degrade toxic compounds In mixtures, phenol and p-cresol mutually inhibited each other; the inhibition constants show that phenol degradation is strongly inhibited in the presence of p-cresol rather than reverse o-Cresol enhanced phenol degradation marginally but o-cresol degradation was not affected by the presence of phenolread more

Cellular fatty acid patterns inPseudomonas sp. CF600 during catechol and phenol degradation in media supplemented with glucose as an additional carbon source
TL;DR: In this paper, the influence of glucose as an additional, easily degradable carbon source on fatty acid profiling in Pseudomonas sp. CF600 was studied and the most important changes were associated with saturation level of fatty acids and cyclopropane fatty acid contents.
Degradation of dual phenolics by a moderately halophilic bacterial consortium and its degradation products
TL;DR: Metabolites formed during the degradation of dual substrates showed that the consortium followed ortho cleavage pathway during the degrade, showing the biodegradability of phenolic substrates by a moderately halophilic bacterial consortium isolated from saline environment.

Evaluation of o-cresol degradation potential by a strain of Pseudomonas aeruginosa S8
TL;DR: The results showed that P. aeruginosa S8 strain has a high o-cresol biodegradation potential; it could degrade completely 1250 mg L−1 o- cresol within 85 h and was slightly affected by alkalinity, presence of heavy metals and salinity.

Kinetics of growth and multi substrate degradation by an indigenous mixed microbial culture isolated from a wastewater treatment plant in Guwahati, India
TL;DR: An indigenous mixed culture of microorganisms, isolated from a sewage treatment plant, was investigated for its potential to simultaneously degrade phenol and m- cresol during its growth in batch shake flasks and showed that phenol was degraded preferentially and earlier than m-cresol.

Substrate interactions of benzene, toluene, and para-xylene during microbial degradation by pure cultures and mixed culture aquifer slurries.
TL;DR: In this paper, the degradation of benzene, toluene, and p-xylene was investigated in sandy aquifer material and by two pure cultures isolated from the same site.

Kinetics of competitive inhibition and cometabolism in the biodegradation of benzene, toluene, and p‐xylene by two Pseudomonas isolates.
TL;DR: Two Pseudomonas species were isolated from an aerobic pilot‐scale fluidized bed reactor treating groundwater containing benzene, toluene, and p‐xylene, and batch tests using paired substrates revealed competitive inhibition and cometabolic degradation patterns.

The Kinetics of Cometabolism
TL;DR: Three previously proposed models describing the kinetics of cometabolism by resting cells are compared, and the interrelationships and underlying assumptions for these models are explored.

Effects of co-occurring aromatic hydrocarbons on degradation of individual polycyclic aromatic hydrocarbons in marine sediment slurries.

TL;DR: The evidence suggests that exposure of marine sediments to a particular PAH or benzene results in the enhanced ability of these Sediments to subsequently degrade that PAH as well as certain other PAHs.

Substrate interactions during aerobic biodegradation of benzene.
TL;DR: The experiments indicated that toluene- and o-xylene-degrading bacteria are also able to degrade benzene, whereas naphthalene-, 1,,4-dimethylnaphthalenes-, and phenanthrene-degarading bacteria have no or very little benzene-degRading ability.
