This study aimed to identify effective strategies for the sustainable production of natural astaxanthin by Phaffia rhodozyma. The combination of titanium dioxide (TiO2) and rapeseed oil boosted astaxanthin production in P. rhodozyma PR106 to 47.31 mg/L, a 6.24-fold increase compared to the control....
