Influence of the initial complex nutrient concentration [CNS] (symbols: ▵, 0.5 [CNS]; ○, 1.0 [CNS]; ⋄, 2.0 [CNS]; □, 3.5 [CNS]) on cell growth (a), lactic acid production (b), and bacteriocin activity (c) for L. sakei CTC 494 in (modified) MRS broth at a controlled temperature of 25°C and pH 5.5. Data points for 1.0 [CNS] represent the mean of three repeats. Full lines are according to the model.
