Figure 2From: Biochemical and molecular characterisation of Tetrahymena thermophila extracellular cysteine proteasesGrowth curve and secretion kinetics of proteases. A shows the mean cell titers (curve with crosses) and protease activities (bars) during shaker flask cultivation of T.thermophila cells. Error bars represent standard errors of three independent experiments. B depicts the cell titers (curve with crosses) and protease activity (bars) during the fermentation used for identification of extracellular proteases are shown.Back to article page
