The bacterial metabolism of 2,4-xylenol

Bacterial metabolism of 2,6-xylenol.

Strain DM1, a Mycobacterium sp. that utilizes 2,6-xylenol, 2,3,6-trimethylphenol, and o-cresol as sources of carbon and energy, was isolated. Intact cells of Mycobacterium strain DM1 grown with 2,6-xylenol cooxidized 2,4,6-trimethylphenol to 2,4,6-trimethylresorcinol. 4-Chloro-3,5-dimethylphenol prevents 2,6-xylenol from being totally degraded; it was quantitatively converted to 2,6-dimethylhyd...

Gentisic acid and its 3- and 4-methyl-substituted homologoues as intermediates in the bacterial degradation of m-cresol, 3,5-xylenol and 2,5-xylenol.

1. Intact cells of a non-fluorescent Pseudomonas grown with m-cresol, 2,5-xylenol, 3,5-xylenol, 3-ethyl-5-methylphenol or 2,3,5-trimethylphenol rapidly oxidized all these phenols to completion. 3-Hydroxybenzoate and 2,5-dihydroxybenzoate (gentisate) were also readily oxidized. 2. 3-Hydroxybenzoic acid and 2,5-dihydroxybenzoic acid were isolated as products of m-cresol oxidation by cells inhibit...

Bacterial Metabolism

Carbohydrat,es are fermented by Clostridium acetobutylicum and related microorganisms with the formation of acetic acid, n-butyric acid, acetone, ethanol, and n-butanol. It has been conclusively proved that the butanol arises by the reduction of the butyric acid (1, 2). As yet, however, there is no exact information as to the sequence of reactions by which butyric acid is formed from glucose by...

Bacterial metabolism of arginine.

Measurement of lipid hydroperoxides by the ferric-xylenol orange method (1) characteristics of the ferric-xylenol orange/membrane phosphatidylcholine complex.

The ferric-xylenol orange (FOX) method for measurement of hydroperoxides is based on a technique that employs reduction of peroxides in an acidic condition by Fe2+ and formation of the colored ferric-xylenol orange (XO/Fe3+) product with a peak at 560 nm. The 560 nm absorbance peak of XO/Fe3+ shifts to a 610 nm peak with high absorption intensity in the presence of phosphatidylcholine. This is ...
