摘要：

Aim: To produce high laccase activities from the white-rot fungus Trametes hirsuta in an in-house air-lift bioreactor (ALB). Methods and Results: Trametes hirsuta was grown in a 6-l ALB. A fed-batch strategy with glycerol as an addition resulted in maximum laccase activity of 19 400 U l(-1), which was the highest reported from the fungus. Conclusion: The ALB configuration with additional glycerol resulted in high laccase activities. Significance and Impact of the Study: This study provides useful information on how to produce high concentrations of laccase.
