The strains were cultured at different temperatures in YPD medium containing 20 g L-1 glucose. The specific growth rates (μ), the biomass yield (expressed as dry weight grams per litre of culture) and the biomass volumetric productivities (QX) are reported as a function of growth temperature. The values are means of three independent experiments, with standard deviations always lower than 5%. Superscripts within a column (symbols) and within a row (letters) indicate statistically similar means, P > 0.05.
