Maximizing the simultaneous production of lipids and carotenoids by Rhodosporidium toruloides from wheat straw hydrolysate and perspectives for large-scale implementation.

This study aimed to select fermentation conditions able to simultaneously maximize the production of lipids and carotenoids by oleaginous yeast cultivated in wheat straw hydrolysate. An evolved strain of Rhodosporidium toruloides with improved tolerance to toxic compounds present in hydrolysate medium was used. Experiments were performed in order to investigate the effect of the temperature and inoculum load on the production of lipids and carotenoids by R.
