Figure 3.3 Effect of temperature on Rhodotorula glutinis mutant 32 during batch cultivation at 20 °C (ο) and 30 °C (g). Under similar conditions at 30 °C, maximum specific carotenoid production was found to be 0.46 mg/g/h during 40-44 h. β-Carotene was the major carotenoid produced but substantial amount of torulene was also produced, simultaneously. At the end of the fermentation (88 h), β-carotene, torulene and torularhodin were present in the
