Four white-rot fungi, Pleurotus eryngii, Polyporus versicolor, Pleurotus ostreatus and Fomes lignosus, are tested for their abilities to produce lignin peroxidase, manganese peroxidase and laccase in N-limited and N-rich media with shake culture. The four white-rot fungi only produce manganese peroxidase and laccase. Pleurotus eryngii and Pleurotus ostreatus are selected, due to their high enzyme activities, for the degradation and decolorization of alkali lignin.

The soil had great population of bacteria, but the fungi quantity is excessive which may cause the multiplication of germina. As base-fertilizer, the slowed-release fatty had positive influence on soil fast-effect nutrient, but the organism quality is small, the soil enzyme activity with microorganism activity both low. Soil EC, total nitrogen, available nitrogen, available phosphorus and organic matters were significantly negative related to the soil pH. Soil total nitrogen was positive significantly related to soil available nutrient.
土壤中pH值与土壤EC值、土壤全氮、速效氮、速效磷、有机质含量呈显著负相关,土壤全氮含量与土壤速效养分含量有极显著正相关关系,而且土壤有机质含量与土壤速效养分之间也有相互促进的作用,所以土壤养分的平衡效果非常重要,有机肥处理后土壤养分全面,肥力较高。

C. gloeosporioides mycelium grew well on media with fructose and glucose as carbon source while sorbose and starch promoted sporulation. The mycelia of C. dematium grew well with maltose as carbon source while starch promoted sporulation. Of the nitrogen sources tested, organic nitrogens were beneficial for both mycelial growth and sporulation but chemical nitrogens suppressed both growth and sporulation.
