Bioprocess optimization and purification of DLA produced using food and fishery waste

Key Points

• The aim is to optimize the bioprocess and purification of d-lactic acid produced from food and fishery waste.
• Utilized engineered Yarrowia lipolytica for d-lactic acid production.
• Employed food waste hydrolysate and fish protein hydrolysate as substrates.
• Applied statistical methods and ANN-GA optimization techniques.
• Achieved d-lactic acid yields of 0.94 g g−1 under optimal conditions.
• Utilized renewable waste sources for sustainable d-lactic acid production.
