Abstract:

Laccase was produced by Coriolopsis rigida using barley bran as substrate in solid-state fermentation (SSF) and also by submerged fermentation (SmF). The best results were obtained in SSF with twice the amount of laccase production. Laccase could be produced from repeated batch cultures of SSF over 30 days. The laccase degraded several polycyclic aromatic hydrocarbons (PAHs) in vivo and in vitro. The addition of an effective mediator, 1-hydroxybenzotriazol (50 µM), during in vitro treatment increased the degradation rate.
