The filtration properties of three mycelial cultures ( Streptomyces griseus, Streptomyces tendae , and Penicillium chrysogenum ) have been measured and quantified in terms of standard filtration equations. Three of the filtration parameters, the hyphal density, the index of compressibility, and the Kozeny constant, were found to vary systematically with broth age and with the visually observed morphology (i.e., pellets vs filaments). Since broth age and mycelial morphology both have a strong influence on bioreactor productivity, it is suggested that filtration could be used for on‐line monitoring of mycelial fermentations.
