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

TL;DR: Pseudomonas flourescens NCIM 2100 was obtained from NCL, Pune, India, that was adapted to growth on 4 amino 1-1 azo benzene 3,4-Disulfonic acid that was tested by UV, (1)H NMR, and IR spectroscopy for its ability to degrade the dye.

Evaluation of the potential of biodegradation for the disposal of cutting fluid from the machining of uranium
TL;DR: Downstream processing of the biotreated fluid by ultrafiltration and adsorption onto activated charcoal produced a waste stream that would qualify as aqueous radioactive waste, albeit in a volume which would make the overall process inefficient.

Changes of microbial community structures and functional genes during biodegradation of phenolic compounds under high salt condition.
Ping Wang,Yuanyuan Qu,Jiti Zhou +2 more
TL;DR: The changes of microbial community structures and functional genes during the biodegradation of single phenol and phenol plus p-cresol under high salt condition were explored and it was found that the phenol-fed system (PFS) exhibited stronger degrading abilities and more stable biomass than that of the phenolic compounds degradation system (PCFS).

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.
James E. Bauer,Douglas G. Capone +1 more
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.
