Carbohydrate carbon sources induce loss of flocculation of an ale-brewing yeast strain.
AIMS To identify the nutrients that can trigger the loss of flocculation under growth conditions in an ale-brewing strain, Saccharomyces cerevisiae NCYC 1195. METHODS AND RESULTS Flocculation was evaluated using the method of Soares, E.V. and Vroman, A. [Journal of Applied Microbiology (2003) 95, 325]. Yeast growth with metabolizable carbon sources (glucose, fructose, galactose, maltose or su...
متن کاملInfluence of preserved brewing yeast strains on fermentation behavior and flocculation capacity
Preservation methods on the physiological and brewing technical characters in bottom and top brewing yeast strains were investigated. The preserved yeasts were reactivated after 24 months storage and grown up to stationary phase. The samples of filter paper storage indicated a higher cell growth and viability during propagation than those of nitrogen and lyophilization storage independent on pr...
متن کاملFlocculation 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 is known as the "addition" model. The second, proposed by Stratford is known as the "cascade" model. The simulations show that the latter exhibits a better qualitative agreement with available experimenta...
متن کاملApplications of Yeast Flocculation in Biotechnological Processes
A review on the main aspects associated with yeast flocculation and its application in biotechnological processes is presented. This subject is addressed following three main aspects – the basics of yeast flocculation, the development of “new” flocculating yeast strains and bioreactor development. In what concerns the basics of yeast flocculation, the state of the art on the most relevant aspec...
متن کاملThe Importance of Trehalose in Brewing Yeast Survival
Originally, trehalose was believed to function only as a reserve carbohydrate similar to glycogen. It is now known that the degradation of trehalose yields little energy and whilst it can serve as a source of carbon skeletons for biosynthesis, it mainly functions as a membrane stabiliser and protectant for yeast cells under stress. (O'Connor-Cox et al, 1996). The significance of trehalose as an...
