Pseudomonas sp. WR912 was isolated by continuous enrichment in three steps with 3-chloro-, 4-chloro-, and finally 3,5-dichlorobenzoate as sole source of carbon and energy. The doubling times of the pure culture with these growth substrates were 2.6, 3.3, and 5.2

The aim of this study was to determine the urinary excretion of dimethylhippuric acids (DMHAs) in humans after experimental chamber exposure to trimethylbenzene (TMB) vapor. The DMHAs have been put forward as suitable biomarkers of exposure to products containing TMBs

Here we report that the bacterial catabolism of 4-hydroxy-3,5-dimethylbenzoic acid 1 takes a different course in Rhodococcus rhodochrous N75 and Pseudomonas sp. strain HH35. The former organism accumulates a degradation metabolite of the acid which we isolated and identified as

The possibility of evaluating occupational exposure to mesitylene based on the determination of unchanged solvent in capillary blood or 3,5-dimethylbenzoic acid in urine was investigated. The volunteers were exposed to mesitylene in a toxicological chamber (range 10-150 mg/m3). Concentrations of
