The effect of parabens on DNA, RNA and protein synthesis in Escherichia coli and Bacillus subtilis.
The effect of methyl, propyl and butyl esters of p-hydroxybenzoic acid on DNA and RNA synthesis has been tested in toluenized cells of Escherichia coli and Bacillus subtilis. Both RNA and DNA synthesis of these bacteria were inhibited. The inhibitory concentrations were higher than those previously reported for growth inhibition. Protein synthesis in cell-free extracts (S-30 fraction) of B. subtilis was even more sensitive to parabens than DNA and RNA synthesis, while protein synthesis in Esch. coli was largely unaffected.
