One-Pot Consolidated Bioprocessing of Waste Potatoes to L-Malic Acid by a Thermotolerant and Metabolically Versatile Aspergillus terreus BD Isolate

Key Points

• The aim is to investigate the production capabilities of Aspergillus terreus BD isolate for L-malic acid from waste potatoes.
• Utilized a thermotolerant Aspergillus terreus BD isolate under fermentation conditions at 45°C.
• Assessed the production of L-malic acid and itaconic acid.
• Conducted one-pot consolidated bioprocessing to optimize output.
• The Aspergillus terreus BD isolate produced significant amounts of L-malic acid at 45°C under optimized conditions.
• Itaconic acid was also produced but in lesser quantities compared to L-malic acid.
