Abstract

The laccase activity of a low-temperature strain of Volvariella brumalis was studied using different lignocellulosic biomasses for liquid fermentation. The results showed that the laccase activity induced by wheat bran or pressed rapeseed residue was higher than the other auxiliary cultivation substrates. Compared to other primary cultivation substrates, Quercus acutissima sawdust and rice straw not only stimulated V. brumalis to produce more laccase in liquid fermentation, but also promoted better mycelial growth in solid-state fermentation. Therefore, these agricultural and forestry wastes should be prioritized as culturing materials of V. brumalis for laccase high-secretion and hyphal growth to increase production of V. brumalis.
