Evaluation of lipid peroxidation for cells stressed with lactic acid. Cells were grown in minimal medium until the exponential phase was reached and then they were treated or not with a pulse of lactic acid 46 g/L at pH 3. After 30 min the cells were collected and the levels of MDA were evaluated. Dark grey bars cells shocked with LA. Light grey bars control. *p ≤ 0.05 Student’s t test
