title: Effect of supplements Mn2+, Cu2+, and aromatic compounds and Penicillium decumbens on lignocellulosic enzyme activity and productivity of Catathelasma ventricosum.
abstract: This is the first report on using Catathelasma ventricosum for production of fruiting body and lignocellulosic enzymes. To improve the laccase activity and productivity of mushroom, the substrate was added with different supplements (eight aromatic compounds, Mn2+, and Cu2+). Based on the results, all these supplements can improve the laccase activity and productivity of C. ventricosum, and it seems that there is a critical value of laccase activity that affects the productivity of C. ventricosum. In addition, when Penicillium decumbens was inoculated into the substrate that had been cultivated with C. ventricosum for 20 days, the highest values of laccase activity, FPA activity, and productivity of C. ventricosum were obtained. Moreover, the laccase activity showed a positive correlation with the productivity of C. ventricosum. Finally, the effect of Mn2+, Cu2+, and P. decumbens on laccase activity was investigated by response surface methodology (RSM).
