摘要

The main purpose of this study is to investigate the effect of Phanerochaete chrysosporium (one of the white rot fungi) on the pulping properties of Ma Bamboo (Dendrocalanms latiflorus) . The experimental results are summarized as follows: 1. The change of chemical composition after bio-pretreatment. (1) Regarding to the content of cellulose, in the first 10 days, the content of cellulose decreased significantly. In 20～40 days, the content of cellulose decreased slightly. This phenomenon was related to the activity of Phanerochaete chrysosporium. In the first stage of metabolism, the white-rot fungus degraded the cellulose for food. (2) Regarding to the lignin content, in the first 10 days the content of lignin had no change. In 20～30 days, the content of lignin decreased significantly. After that lignin decreased slight. This phenomenon was related to the activity of Phanerochaete chrysosporium. After the first metabolism stage, the white-rot fungus degraded the lignin for food. (3) Concerning the content of hemicellulose, in 10～40 days the content of hemi-cellulose decreased significantly. This phenomenon was related to the activity of Phanerochaete chrysosporium. 2. Kraft pulping with bio-pretreatment. (1) During the first 10 days, some of the physical properties of paper decreased to some extent. In 20～30 days, all of the physical properties of paper increased. After that the paper physical properties became stable. (2) This phenomenon was related to the activity of Phanerochaete chrysosporium. During the first metabolism stage, the white-rot fungus degraded cellulose for food. 3. Thermomechanical pulping with bio-pretreatment. (1) After bio-pretreatment, all power consumption decreased significantly. (2) After bio-pretreatment, all the physical properties of paper increased to some extent, especially the burst index.
