1 Batch cultures were obtained at 6, 20, and 36 hours of incubation while continuous cultures were obtained at dilution rates (D) ranging from 0.36 to 1.92 h-1. The incubation time for the bath cultures where the maximum are reached are indicated into brackets. For continuous culture, into brackets are shown the dilution rates where the maximum are obtained. 2 CECT: Colección Española de Cultivos Tipo (Spain). ATTC: American Type Culture Colection (USA). 3 The values were obtained from skew-Laplace (*) and log skew-Laplace (**) fits in the studied batch (B) and continuous (C) cultures.
