Sequential carotenoids extraction and biodiesel production from Rhodosporidium ...
Passarinho, Paula; Oliveira, Bruno; Dias, Carla; Teles, Marta; Reis, Alberto; Silva, Teresa Lopes daABSTRACT: A new process for co-extraction and separation of fatty acids and carotenoids from Rhodosporidium toruloides NCYC 921 biomass in order to achieve full exploitation of the yeast lipidic fraction is described. A saponification of the wet yeast biomass was performed using a potassium hydroxide solution (1.1 M) in ethanol 96%, at 65 °C for 180 min. In the carotenoid extraction step, a biphasic system with...
Biofuels and high value added products from the yeast Rhodosporidium toruloides...
Reis, Alberto; Dias, Carla; Caldeira, João; Teles, Marta; Oliveira, Bruno; Passarinho, Paula; Silva, Teresa Lopes daSingle-cell oils (SCO) have been considered a promising source of 3rd generation biofuels mainly in the final form of biodiesel. However, its high production costs have been a barrier towards the commercialization of this commodity. The fast growing yeast Rhodosporidium toruloides NCYC 921 has been widely reported as a potential SCO producing yeast. In addition to its well-known high lipid content (that can be ...
