Abstract :
A new isolated strain of Sporobolomyces ruberrimus H110 was cultivated on technical glycerol as carbon source and effect of different temperatures and pH on the growth and pigmentation was studied. The maximum concentration of total carotenoid was 3.84 mgg-1 including torularhodin (3.70 mgg-1) and β-carotene (0.14 mgg-1) using 19ºC at pH 6, but the highest amount of the maximum specific growth rate was obtained (µmax = 0.094 h-1) at 27ºC. The growth yield (Yx/s ) was equal to 0.52 ± 0.01 g g-1 with a correlation coefficient value of 0.98.
