title: [White-rot fungi combinations impact on enzyme productions].
abstract: In this study, the maximum laccase (Lac) activities by single white-rot fungus and combining white-rot fungi were investigated. The optimal combinations of white-rot fungi were obtained by comparing the maximum Lac activities and the time of achieving the maximum Lac activity. The results showed that the synergy of white-rot fungi Polyporellus picipes and Pleurotus ostreatus improved the secretion of the laccase, with the enzyme production of 50.45 U x mL(-1), as well as the combination of white-rot fungi Polyporellus picipes, Pleurotus ostreatus and Pseudotrametes gibbosa promoted the laccase production of 75.98 U x mL(-1). However, the combination of white-rot fungi Polyporellus picipes, Pleurotus ostreatus and Pycnoporus sanguineus generated antagonistic effect, with the enzyme production of 2.91 U x mL(-1). Both synergistic and antagonistic effects among the white-rot fungi results in different time for achieving the maximum Lac activity of white-rot fungi.
