    Notes: Trypticase Soy Broth containing butylated hydroxyanisole (BHA; 0, 50 or 100 ppm) and sodium chloride (NaCl: 3, 5, or 7%) at pH 5.0. 6.0, or 7.0 was inoculated with Staphylococcus aureus S-6 to evaluate the antimicrobial effectiveness of these chemicals in concert. BHA at the levels tested became more effective in preventing growth as the pH of the medium was decreased and the NaCl concentration was increased. The combination of 100 ppm BHA with 5 or 7% NaCl at all three pH levels tested had the strongest bactericidal effect.

    Notes: The influence of oxidation-reduction potential (Eh) on the outgrowth, toxin production, and chemical inhibition of C. botulinum(10755A) was investigated. Strict anaerobic procedures and prereduced media were utilized in all growth experiments. No difference in growth or toxin formation in Trypticase Soy Broth (TSB) at an Eh7 of -60 mv or in TSB at an Eh7 of -145 mv was observed. However, growth and toxin production were delayed and/or decreased in the higher Eh medium as compared to the lower Eh medium by the addition of sodium chloride (5.0% and 6.0%), hydrogen ion concentration (pH 5.2 and 5.3), and sucrose (30%) to TSB.
