Laccase activity secreted by Pleurotus eryngii Han 1787 and Lentinus edodes Han 1788 grown on six types of agroindustrial wastes was investigated. Maximum laccase activity of P. eryngii Han 1787 on Ulmus pumila, Juniperus formosana, Pinus tabuliformis, cottonseed shell, corncob, and leaf of corncob was nearly 5.77-fold, 2.37-fold, 2.78-fold, 2.81-fold, 11.53-fold, and 6.73-fold higher than that of L. edodes Han1788 on corresponding agroindustrial wastes. In general, the capacity of secreting laccase of P. eryngii Han 1787 was superior to that of L. edodes Han 1788. Furthermore, laccase activity of P. eryngii Han 1787 on the leaf of corncob, the corncob, Ulmus pumila, and Juniperus formosana was relatively stable during the whole fermentation process. Different fungi showed different preferences in different agroindustrial wastes to secret laccase on whole fermentation stage. The presence of leaf of corncob was useful for improving laccase activity of P. eryngii Han 1787, while L. edodes Han 1788 was more preferred to produce laccase along with the presence of Juniperus formosana. These results were preliminary conducive in laying the foundation for increasing industrial laccase-producing strains and producing low-cost laccase.
