Identification of a novel and thermostable laccase from Bacillus velezensis GLY4 and its application in the biotransformation of aflatoxins

Key Points

• Laccase demonstrated effective biotransformation of aflatoxins, indicating a significant reduction in toxicity.
• The thermostable laccase retained over 80% activity at elevated temperatures, showing robust enzymatic performance.
• Analysis of enzymatic properties revealed a strong affinity for aflatoxin substrates, promoting efficient transformation rates.
• Implications extend to food safety, highlighting the potential for novel biocatalysts in detoxifying harmful compounds.
