A scale-up strategy into 200 l pilot-scale for the production of the antibiotic gallidermin by Staphylococcus gallinarum Tu 3928 was developed. Large-scale fermentations were simulated by consecutive liquid cultures of smaller scale. Afterwards, optimised cultivation conditions were transferred to pilot-scale. Best results were achieved by addition of Maltose during the late production phase leading to a final concentration of 330 mg gallidermin per litre. Compared to the concentrations found in a non-pulsed pilot-scale fermentations this is an increase of 20-30%.
