4.2 mg L1 of total carotenoids and 86.2 g L1 of biomass containing
26.7% lipids from R. glutinis, cultivated in a medium composed
of glucose, yeast extract and salts. b-carotene represented 68.4%,
torularhodin and torulene represented 21.5% and 10.1% of total
carotenoids, respectively. Freitas et al. (2014) studied the production
of lipids and carotenoids from Rhodosporidium toruloides using
carob pulp syrup as low-cost carbon source and reached productivities
of 1.9 g L1 h1 and 9.79 lg L1 h1 for lipids and total carotenoids,
respectively. Other authors that reported the use of low cost
carbon sources to produce carotenoids were Buzzini and Martini
(1999), reaching 5.95 mg L1 total carotenoids from grape must
by R. glutinis and Aksu and Eren (2005), reaching 89 mg L1 from
molasses sucrose and 35 mg g1 dry cells from whey lactose by
Rhodotorula mucilaginosa.
