Vw. Johnson et al., UTILIZATION OF MOLASSES FOR THE PRODUCTION OF FAT BY AN OLEAGINOUS YEAST, RHODOTORULA-GLUTINIS IIP-30, Journal of industrial microbiology, 14(1), 1995, pp. 1-4
Rhodotorula glutinis is known to produce fat when cultivated under nit
rogen-limiting conditions. Economically, molasses is an ideal substrat
e, however, due to the presence of nitrogen in molasses, the lipid yie
ld obtained ii much lower than that obtained from glucose or sucrose.
Higher yields were obtained using molasses in a fed batch fermentation
supplemented with glucose or sucrose during the lipid accumulation ph
ase. The fatty acids profile of the lipids thus produced, using a very
simple and economical medium, was similar to that obtained from gluco
se and sucrose.
