The flow behavior of suspensions of yeast (Candida utilis) grown on sauerkraut waste was studied as a function of concentration at 25.8 C. Suspensions containing 5.8, 21.7, 22.6, 23.6, 24.7 and 27.0% dry solids behaved as Newtonian fluids. The viscosity of these suspensions increased exponentially with the concentration of dry solids. A 29.2% suspension showed time dependent shear-thinning behavior. The non-Newtonian characteristics of the suspension could be described by both the Power law and the Casson flow models.
