Notes:
A thermotolerant yeast species of Lodderomyces elongisporus EH 60 was isolated and physiologically characterized. This yeast possesses a high specific growth rate with μmax = 0.61 h-1. The dependence of the specific growth rate and cell yield on temperature, dilution rate, sucrose concentration and pH-value is investigated. Sucrose concentrations greater than 10 g/l inhibit the growth velocity.The specific growth rate μ can be calculated by a simple combination equation in the form: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} {\mu \, = \,\mu _{\max } \frac{{\rm S}}{{{\rm K}_{\rm s} \, + \,{\rm S}}}\, - \,K_2 \cdot S^{K_1 } } \\ {{\rm (growth term)}\,{\rm (inhibition term)}} \\ \end{array} $$\end{document}.The total optimum values for a sucrose-based continuous growth process with regard to the optimum cell yeild are: YS = 0.50 g DM/g S. Topt. = 38,6 °C and Dopt. = 0,35 h-1. The function YS = f(D, T) is represented by a total model.
