AbstractAn efficient strategy for laccase production in Trametes versicolor cultures was developed using vanillic acid as the inducer. The optimized vanillic acid treatment strategy consisted of exposing 2-day-old mycelia cultures to 80 mg/L vanillic acid. After 4 days, laccase activity of 588.84 U/L was achieved in flasks which represented a 1.79-fold increase compared to the control. In 200-L airlift bioreactor, the maximal laccase activity reached up to 785.12 U/L using the optimized vanillic acid treatment strategy. The zymograms of culture supernatants revealed three bands with laccase activity, among which Lac1 and Lac2 were abundant laccase isoforms constitutively expressed, and Lac3 was an inducible isozyme by vanillic acid. The results of real-time quantitative PCR showed that the transcription level of lcc in T. versicolor cultures grown with vanillic acid for 7 days was about 5.64-fold greater than that without vanillic acid in flasks. In 200-L airlift bioreactor cultures of T. versicolor with addition of vanillic acid, the transcript level of lcc at day 7 was 2.62-fold higher than that in flasks with vanillic acid due to the good mass transfer and oxygen supply in the bioreactor system. This study provides a basis for understanding the induction mechanism of vanillic acid for laccase production and has good potential for industrial applications.
