Summary

Broth from batch fermentations with Aureobasidium pullulans was investigated with a vibrating reed viscometer which showed to be sensitive to changes in the concentration of exopolysaccharide as well as in the concentration of mycelial biomass. Samples were withdrawn at 11.5,13.5, and 20 hours after inoculation and measurements on dilution series of mycelium showed that the change in the age and therefore in the morphology of the mycelium markedly affected the sensor signal.
