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 simultaneously maximize the production of lipids and carotenoids by oleaginous yeast cultivated in wheat straw hydrolysate. An evolved strain Rhodosporidium toruloides with improved tolerance toxic compounds present hydrolysate medium was used. Experiments were performed order investigate effect temperature inoculum load on R. toruloides. Results revealed that accumulation both products can be maximized when performing at 17 °C using 3.5 g/L inoculum. maximum simultaneous opens up new perspectives for establishment a feasible more sustainable large-scale process carotenoids. Even corresponding only 1% cell mass, due high market value, would account than 90% total income industrial plant.
