This work evaluated the lipid and protein growth and synthesis capacity by Saccharomyces cerevisiae, Rhodotoruda mucilaginosa, Candida lipolytica, a yeast isolated from vinasse lakes and Corynebacterium glutamicum in 10% molasses and sugar cane crude vinasse. All microorganisms grew both in molasses and vinasse. The highest growth in crude vinasse was performed by R. mucilaginosa (7.05 g/L), and in 10% molasses, by C. lipolytica, yielding 6,09 g/L. In vinasse, the highest protein content in the biomass was produced by S. cerevisiae (50.35%) and in 10% molasses, by C. glutamicum (46,16%). C. lipolytica and R. mucilaginosa showed the best lipid production, above 20% and 18%, respectively, both in vinasse and in molasses.Downloads
