Description
  • Growth of Rhodotorula glutinis and Rhodotorula mucilaginosa was studied under optimal and stress cultivation conditions at 10 and 20°C for 14 days. The method of image analysis was used to determine the size of colonies. The linear mixed effects model implemented in the statistical program S PLUS was applied to analyze repeated measurements. Two-phase kinetics was confirmed and the mean growth rates in the second linear phase under various stress conditions were estimated. The results indicated that R. mucilaginosa had a higher growth rate than R. glutinis under all cultivation conditions. The highest growth rate was observed during cultivation of R. mucilaginosa in media with 2% of NaCl at 20°C. The impact of neglecting the fact that repeated data are not independent and using the classical regression model instead of the mixed effects model was demonstrated through the comparison of confidence intervals for parameters based on both approaches. While the point estimates of the corresponding parameters were similar, the width of confidence intervals differed substantially.
