Abstract

Streptomyces antibioticus Tü 6040 is the producer of simocyclinones, which belong to a novel family of angucyclinone antibiotics some of which show antitumor activities. Growth and antibiotic production is dependent on the medium composition, especially on the carbon and nitrogen source, and on the fermentation conditions. The best results with respect to antibiotic productivity were achieved using a chemically defined medium with glycerol and L-lysine as carbon and nitrogen source, respectively, in an airlift fermenter with minimised shear stress at low gas flow rates withour oxygen limitation. These conditions led to a homogeneous formation of pellets of 1-2 mm in diameter and guaranteed reproducible product yields of the main compound, simocyclinone D8, in the range of 300 mg/l.
