Abstract:
The synthesis of single cell oil (SCO) as alternative feedstock for the production of biodiesel as well as the formation of carotenoids as value added by-product of red yeast Rhodotorula glutinis cultivated on wastewaters from sugar refinery and beer production was investigated. Additionally, the ability of R. glutinis to utilize maltose as main carbon source in brewery wastewaters was examined. R. glutinis was able to produce biomass both on sugar refinery (4.86 g L-1) and brewery (4.25 g L-1) wastewaters. No lipid production was observed during growth on sugar refinery wastewaters probably due to low amounts of yeast available carbon sources. Cultivated on different brewery wastewater treatments, lipid production reached a maximum of 2 g L-1. Maltose was consumed in small quantities. No carotenoids were produced, probably because carbon was utilized in favor of lipid production.
