Agricultural residues, such as lignocellulosic materials (LM), are the most attractive renewable bioenergy sources and are abundantly found in nature. Anaerobic digestion has been extensively studied for the effective utilization of LM for biogas production. Experimental investigation of physiochemical changes that occur during pretreatment is needed for developing mechanistic and effective models that can be employed for the rational design of pretreatment processes. Various-cutting edge pretreatment technologies (physical, chemical and biological) are being tested on the pilot scale. These different pretreatment methods are widely described in this paper, among them, microaerobic pretreatment (MP) has gained attention as a potential pretreatment method for the degradation of LM, which just requires a limited amount of oxygen (or air) supplied directly during the pretreatment step. MP involves microbial communities under mild conditions (temperature and pressure), uses fewer enzymes and less energy for methane production, and is probably the most promising and environmentally friendly technique in the long run. Moreover, it is technically and economically feasible to use microorganisms instead of expensive chemicals, biological enzymes or mechanical equipment. The information provided in this paper, will endow readers with the background knowledge necessary for finding a promising solution to methane production.
农业废弃物，如木质纤维素材料（LM），是最具吸引力的可再生生物能源，在自然界中储量丰富。厌氧消化已被广泛研究，用于有效利用LM生产沼气。为了开发可用于预处理工艺合理设计的机理模型和有效模型，需要对预处理过程中发生的物理化学变化进行实验研究。各种前沿预处理技术（物理、化学和生物）正在中试规模上进行测试。本文对这些不同的预处理方法进行了广泛描述，其中，微氧预处理（MP）作为一种潜在的LM降解预处理方法受到关注，该方法仅在预处理步骤中直接供应有限量的氧气（或空气）。MP在温和条件（温度和压力）下涉及微生物群落，用于甲烷生产的酶和能量较少，从长远来看可能是最有前途且最环保的技术。此外，使用微生物代替昂贵的化学品、生物酶或机械设备在技术和经济上是可行的。本文提供的信息将为读者提供必要的背景知识，以便找到一种有前途的甲烷生产解决方案。
