This study focused on the growth of Saccharomyces cerevisiae MM01 recombinant strains and the respective production of three extracellular heterologous cutinases: a wild-type cutinase and two cutinases in which the primary structure was fused with the peptides (WP)(2) and (WP)(4), respectively. Different cultivation and strategies were tested in a 2-L shake flask and a 5-L bioreactor, and the respective cell growth and cutinase production were analyzed and compared for the three yeast strains. The highest cutinase productions and productivities were obtained in the fed-batch culture, where wild-type cutinase was secreted up to a level of cutinase activity per dry cell weight (specific cell activity) of 4.1 Umg(-1) with activity per protein broth (specific activity) of 266 Umg(-1), whereas cutinase-(WP)(2) was secreted with a specific cell activity of 2.1 Umg(-1) with a specific activity of 200 Umg(-1), and cutinase-(WP)(4) with a specific cell activity of 0.7 Umg(-1) with a specific activity of 15 Umg(-1). The results indicate that the fusion of hydrophobic peptides to cutinase that changes the physical properties of the fused protein limits cutinase secretion and subsequently leads to a lower plasmid stability and lower yeast cell growth, These effects were observed under different cultivation conditions (shake flask and bioreactor) and cultivation strategies (batch culture versus fed-batch culture).
