For its high reactivity and very short half-life, the hydroxyl radical (OH.) in vivo is very difficult to be detected. Usually, it is indirectly quantified by determining 2,3-dihydroxybenzoic acid (2,3-DHBA) and 2,5-dihydroxybenzoic acid (2,5-DHBA), which are the reaction products of

The growth rates of Pseudomonas putida KT2442 and mt-2 on benzoate, 4-hydroxybenzoate, or 4-methylbenzoate showed an exponential decrease with decreasing oxygen tensions (partial O2 tension [pO2] values). The oxygen tensions resulting in half-maximal growth rates were in the range of

Recent kinetic extensions of the nucleation theorem suggest that the logarithm of the steady-state nucleation rate has strong multilinear dependence on the log concentrations of condensable species present in the vapor phase. A further remarkable result is that the coefficients

FT-Raman and FT-IR spectra for 2-hydroxy-p-toluic acid molecule had been recorded in the regions 3500-100 cm(-1) and 4000-400 cm(-1), respectively. Vibrational frequencies have been calculated in optimum state by employing density functional theory (DFT) and Hartree Fock (HF) methods with

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
