摘要
通过对国外引进和国内筛选的白腐菌菌种进行酶学、红麻发酵、全杆红麻生物-硫酸盐法制浆研究,初步明确了不同菌种的红麻发酵与生物制浆性能存在较大差异,菌种S4(Trametes sanguinea(L:Fr.)Lloyd)是较好的红麻生物制浆菌种,它能在两周左右完成红麻发酵,其硫酸盐纸浆粗、细浆得率相对较高,具有较高的漆酶、木质素过氧化物酶酶活,漂白浆白度较高、氯耗较低。基本明确硫酸盐法可能并不适合全杆红麻生物制浆,其粗、细浆得率较未经生物处理的明显降低,纸浆的物理性能也有所变差。
Kenaf is one of the most suitable materials for research and development of bio-pulping. After systematic study of fermentation capability, enzymatic activity, and bio-kraft pulping for kenaf, Trametes sanguinea （L： Fr. ）Lloyd was selected as the most suitable fungi strain among Ceriporiopsis subvermispora, Phanerochete chrysosporium, Fomes lignosus of different origins, which grew very rapidly both on PGA and sterilized kenaf, and had kenaf well colonized in 2 weeks. The laccase and lignin peroxidase activities were the highest in PG and kenaf fermentation for T. sanguinea （L： Fr. ） Lloyd. Higher brightness and lower residual chlorine could also be observed for bio-kraft pulping with such strain. But it revealed that bio-kraft pulping process may not be suitable for kenaf, considering rather low fine and coarse pulp yields and inferior pulp physical properties. New bio-pulping processes including Bio-APMP and Bio-AQ should be explored.
