Description
Summary:The extensive application of laccase in various fields depends on the supply of a large amount of laccase with high activity and low cost. Interest on the screening of fungal strains suitable for obtaining massive high-activity laccase in solid-state fermentation with suitable low-cost lignocellulosic wastes has increased. The present work determined the laccase secretion from different species belonging to genera Ganoderma and Coriolopsis fermented on different lignocellulosic wastes. Maximal laccase activity was obtained from Ganoderma lingzhi Han 1345 grown on rice straw for 9 days and indicated the capacity of secreting laccase of G. lingzhi Han 1345 was superior to that of Coriolopsis trogii Han 1211, C. strumosa Han 1356, and G. applanatum Han 1578. The presence of cottonseed hull was more favorable for Coriolopsis species secreting laccase, while Ganoderma species were more preferred to secrete laccase on rice straw. Further, the consistent substrate preference in laccase production of different species in the same genus was first exhibited. The results are useful to screen and obtain new species with superior capacity of secreting laccase and suitable low-cost lignocellulosic wastes as fermentation substrate for further industrial application of laccase.
