The isolated Pseudomonas monteilii CR13 is an efficient bacterial strain to biodegrade o-Cresol. The P.
Kinetics for aerobic biological treatment of o-cresol containing wastewaters in a slurry bioreactor: biodegradation by utilizing waste activated sludge.
New metabolic pathway for o-cresol degradation by Pseudomonas sp.
[OUR.sub.max] values for 5-methylresorcinol, p-cresol and resorcinol by the activated sludge of the Kohtla-Jarve biotreatment plant exceeded those for o-cresol and dimethyphenols.
It should be noted that the average [OUR.sub.max] value was 3.3 times higher for p-cresol compared with that for o-cresol. The curves of OUR resulting from the addition of the same amount of p-cresol and o-cresol are illustrated in Fig.
The fact that this value was higher than the values for p-cresol, 5-methylresorcinol, resorcinol and o-cresol indicates that phenol was more readily oxidized by the studied activated sludge than cresols or resorcinols.
Bilirubin has substantial reducing activity, and a mechanism of interference involving the periodate-promoted o-cresol
condensation reaction was also considered.
All polymers are soluble in organic polar solvents such as DMAc, DMF, NMP, and even in less polar solvents like o-cresol
. These polymers are insoluble in solvents such as chloroform, acetonitrile, ethanol, and water.
