Spider silk proteins can be produced with recombinant bacteria. The aim of this thesis was the reaction engineering analysis of the intracellular production of a hydrophobic spider silk protein in stirred tank reactors to reveal possible ways for process intensification. Using minimized amounts of raw materials, a simplified substrate dosing and an appropriate induction strategy, the
E. coli cells could be maximally filled with the spider silk protein applying a high cell density fermentation process. Thus, the product concentration in the reactor was more than doubled.
