Optimization of growth parameters for the production of carotenoids by Rhodotorula gracilis

Response surface methodological studies of
growth parameters for carotenoid production by Rhodotorula
gracilis (ATCC 90950) have been carried out
for three parameters employed, namely glucose concentration
(%), incubation period (days) and volume of
inoculum (ml/100 ml). The results indicated maximum
carotenogenesis (0.054%) at a 10% glucose level with a
2 ml/100 ml volume of inoculum for an incubation period
of 9 days, which was also verified by experimental
data.
