Abstract:
:For continuous production of the antibiotic nikkomycin immobilized cells have been used in a fluidized bed bioreactor. Cells of Streptomyces tendae were immobilized on sintered glass particles. Different biomass concentrations on the particles correspond to different thicknesses of mycelial layers because growth occurs only on the outer surface of the particles. The antibiotic productivity decreased with increasing layer thickness. In fermentations with higher concentrations of both biomass on the particles and dissolved oxygen levels of about 70% the productivity was also limited because of limited oxygen diffusion in the layers.
