Flocculation in brewing yeasts: A computer simulation study

A new simulator, INDISIM-FLOC, based on the individual-based simulator INDISIM, is used to examine the predictions of two different models of yeast flocculation. The first, proposed by Calleja [Calleja, G.B., 1987. Cell aggregation. In: Rose, A.H., Harrison, J.S. (Eds.), The Yeasts, vol. 2. second ed., Academic Press, London, pp. 165–238 (Chapter 7)], is known as the “addition” model. The second, proposed by Stratford [Stratford, M., 1992. Yeast flocculation: a new perspective. In: Rose, A.H. (Ed.), Advances in Microbial Physiology, vol. 33. Academic Press, London, pp. 1–71] is known as the “cascade” model. The simulations show that the latter exhibits a better qualitative agreement with available experimental data.
