Use of sugar cane molasses and vinasse for proteic and lipidic biomass production by yeast and bacteria

Marcia Luciana Cazetta, Maria Antonia Pedrine Colabone Celligoi


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.
