Efficiency of laccase production in a 65-L air-lift reactor for potential green industrial and environmental application

► Green enzyme, laccase, is effectively produced in a 65-L air-lift reactor. ► Extracellular proteins, including laccase, are identified using nano-LC/MS/MS. ► The crude laccase is highly stable over various temperatures. ► The crude laccase can be easily stored at room temperature over one year.
