摘要：
The effects of various physicochemical parameters on the growth of two Kluyveromyces marxianus strains were investigated, including: pH values, sodium chloride, water activity in the medium and temperature. Both yeast strains were unaffected by pH changes. Optimal pH for growth was found to be 4 with both strains, but they were able to develop within the pH 3-8 range. Suitable growth was obtained at temperatures of 4-44-degrees-C and the optimal temperature for growth was 36-degrees-C for both strains. Modelling of this latter parameter is described. Growth of both microorganisms was considerably modified by increased NaCl or decreased water activity in the medium.
