Carotenoids production from red yeasts using waste glycerol as a sole carbon source

Fourteen strains of red yeasts from a culture collection Thailand Institute Scientific and Technological Research (TISTR) were screened for carotenoids production using yeast maltextract medium (YM), basal medium supplemented with either pure glycerol (BMP) or waste glycerol (BMW) as a sole carbon s...

Under the optimized conditions, the maximum total carotenoids content of 1,058.42 μg (g DCW)-1 was achieved.
