| 中文摘要 |
| 研究了白腐菌对硫酸盐木素的降解作用和影响因素。结果发现,2种白腐菌对硫酸盐木素的降解能力不同,培养10d后,木云芝Lu-11的降解率达到74.5%,而黄孢原毛平革菌的降解率为65.6%;分子量在1500-3000kD之间的硫酸盐木素部分被降解最为明显,木云芝的降解产物只有一种主要组分,而黄孢原毛平革菌的降解产物有2种主要组分;培养条件如碳源、氮源、pH值和温度对白腐菌降解硫酸盐木素的作用有明显的影响。 |
| 英文摘要 |
| Black liquor lignin is the main pollutant in the black liquor produced from kraft pulping process of paper-making raw materials.In this paper, effect of white-rot fungi on degradation of black liquor lignin produced from pine kraft cook was studied. Results showed that white-rot fungus could degrade more than 74.5% of black liquor lignin in the medium after 10 days of culture,the main part of black liquor lignin degraded was in the range of 1500-3000kD of molecular weight. Culture factors such as cabon and nitrogen source,pH value in the medium and temperature exerted during the culture had an important role respectively on the effect of degrading black liquor lignin by white-rot fungus. |
