This article is retracted on request of Weihua Wu due to inconsistent errors of intracellular and total beta-glucosidase activities assay and the mycelia weight measurement in this paper. These errors lead to inaccurate results of total and intracellular beta-glucosidase activities, and the normalized endoglucanases and exoglucanases activities and therefore compromise the partial conclusions of this publication.
