Fatty acids profiles and estimation of the biodiesel quality parameters from Rhodotorula spp. from Antarctica
Oleaginous yeasts are a renewable and alternative source of oil for third-generation biodiesel. This work aimed to evaluate the effects of glucose concentration (30?100 g/L) on growth, lipid synthesis, and fatty acids (FA) profile of three Rhodotorula spp. (R. glacialis R15, R. glutinis R4, and R. g...
