Abstract：
Biological pretreatment of wood chips by fungi is a well-known approach prior to mechanical- or chemical pulp production. For this biological approach, a limited number of white-rot fungi with an ability to colonize and selectively degrade lignin are used to pretreat wood chips allowing the remaining cellulose to be processed for further applications. Biopulping is an environmentally friendly technology that can reduce the energy consumption of traditional pulping processes. Fungal pretreatment also reduces the pitch content in the wood chips and improves the pulp quality in terms of brightness, strength, and bleachability. The bleached biopulps are easier to refine compared to pulps produced by conventional methodology. In the last decades, biopulping has been scaled up with pilot trials towards industrial level, with optimization of several intermediate steps and improvement of economic feasibility. Nevertheless, fundamental knowledge on the biochemical mechanisms involved in biopulping is still lacking. Overall, biopulping technology has advanced rapidly during recent decades and pilot mill trials have been implemented. The use of fungi as pretreatment for pulp production is in line with modern circular economy strategies and can be implemented in existing production plants. In this review, we discuss some recent advances in biopulping technology, which can improve mechanical-, chemical-, and organosolv pulping processes along with their mechanisms.
摘要：
在机械或化学纸浆生产之前，通过真菌对木片进行生物预处理是众所周知的方法。对于这种生物学方法，具有定殖和选择性降解木质素的能力的有限数量的白腐真菌用于预处理木片,允许剩余的纤维素被加工用于进一步应用。生物制浆是一种环保技术，可以降低传统制浆工艺的能耗。真菌预处理还减少了木片中的沥青含量，并提高了纸浆质量，力量,和可漂白性。与通过常规方法生产的纸浆相比,漂白的生物浆更容易精炼。在过去的几十年里，生物制浆已经扩大，试点试验达到了工业水平，优化了几个中间步骤，提高了经济可行性。然而，关于生物制浆所涉及的生化机制的基本知识仍然缺乏。总的来说,近几十年来，生物制浆技术发展迅速，中试工厂已经实施。使用真菌作为纸浆生产的预处理符合现代循环经济战略，可以在现有的生产工厂中实施。在这次审查中,我们讨论了生物制浆技术的一些最新进展，这可以提高机械-，chemical-,和有机溶剂制浆工艺及其机理。
