Protein secretion as measured by fluorescence in culture supernatant in shake flasks cultivations. Shake flasks were performed in duplicate, at 150 rpm and 30 °C, and the bars depict the maximum fluorescence level in the strain when DOX (10 μg/mL) was added compared to non-induced conditions (±one standard error). Blue bars fluorescence, Red bars fluorescence per g dry weight
