[Objective] The purpose was to study the optimum conditions of Pycnoporus sanguineus for producing ligninase.[Method] A strain of lignindegrading white-rot fungus was selected from 5 strains of collected fungi and its ligninase production and the optimum conditions for producing ligninolytic enzyme were measured.[Result]It could produce two kinds of ligninase with good thermal stability.Different temperatures,carbon sources,nitrogen sources,acidities,as well as the additions of surfactant had distinct influence on the development of lignin-degrading enzymes of the fungus.The optimum condition was drawn out: 38 ℃,pH=4.5,10 g/L glucose,1.0 g/L tartaric acid ammonium.[Conclusion] The aim of the research was to provide a basis for lignin degradation in practice.
