| Abstract: | Rhodotorula glutinis 22P when co-cultivated with Lactobacillus helveticus 12A in a whey ultrafiltrate synthesizes maximum cell mass and carotenoid concentrations (31.9 g/l and 8388  g/l, respectively) at 30°C. The change in the growth temperature conditions of both cultures influences the carotenogenesis by yeast and the proportion of individual pigments forming up the carotenoids. |
