Abstract
AbstractA 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: .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.
