FIG. 6.

Effect of inhibition of protein synthesis on H₂O₂ accumulation by aerated cultures of L. jensenii CECT 4306. Results shown are for replicate control cultures grown without Fe³⁺ (♦) and replicate cultures grown without Fe³⁺ and subjected successively to 100 μg/ml chloramphenicol, 2 mM Fe³⁺, and aeration at 30-min intervals (▪). Similar data for lack of H₂O₂ accumulation were obtained from cultures grown in the presence of Fe³⁺ and the same cultures treated with chloramphenicol. Error bars show standard deviations.
