Sven Lahme et al.
Applied and environmental microbiology, 78(5), 1606-1610 (2011-12-20)
A novel alphaproteobacterium isolated from freshwater sediments, strain pMbN1, degrades 4-methylbenzoate to CO(2) under nitrate-reducing conditions. While strain pMbN1 utilizes several benzoate derivatives and other polar aromatic compounds, it cannot degrade p-xylene or other hydrocarbons. Based on 16S rRNA gene
C E Kuo et al.
Chemosphere, 45(6-7), 835-842 (2001-11-07)
The composition of the headspace gas affected the growth dynamics of microbial populations and the biotransformation pattern of p-toluic acid in anoxic estuarine sediments. Under CO2 atmosphere, p-toluic acid was transformed by the sediment microorganisms without a lag period, while

Applied microbiology and biotechnology, 50(2), 233-240 (1998-12-05)
Pseudomonas sp. D7-4 and Pseudomonas sp. B13 FR1(pFRC20P) degraded mixtures of chloro- and methyl-substituted benzoates exclusively via an extended ortho pathway, whereas in Pseudomonas putida WR 201 both ortho and meta fission were induced by mixtures of 3-chloro- and 3-methylbenzoate
Sven Lahme et al.
Environmental microbiology, 14(5), 1118-1132 (2012-01-24)
The pathway for anaerobic degradation of 4-methylbenzoate was studied in the denitrifying alphaproteobacterium Magnetospirillum sp. strain pMbN1. Adaptation studies with whole cells indicated substrate-dependent induction of the capacity to degrade 4-methylbenzoate. Differential protein profiling (2D-DIGE) of 4-methylbenzoate- in comparison with
F Junker et al.
Microbiology (Reading, England), 142 ( Pt 9), 2419-2427 (1996-09-01)
Three multicomponent oxygenases involved in the degradation of p-toluenesulfonate and p-toluenecarboxylate and the regulation of their synthesis have been examined in three strains (T-2, PSB-4 and TER-1) of Comamonas testosteroni. Strain T-2 utilizes p-toluenesulfonate as a source of carbon and
