Phaffia rhodozyma Cultivation on Structural and Non-Structural Sugars from Sweet Sorghum for Astaxanthin Generation

•Phaffia rhodozyma cultivation performance depends on sweet sorghum sugar source.•Sweet sorghum juice generates greater astaxanthin titers than bagasse hydrolysate.•53.3 mg/L astaxanthin and 34.9 g/L biomass was produced from sweet sorghum juice.•Bagasse hydrolysate detoxification was necessary to improve astaxanthin generation.•48.9 mg/L astaxanthin and 23.6 g/L biomass was produced from bagasse hydrolysate.
