木质纤维素作为一种可再生的、富含碳水化合物的、全球丰富的生物质来源，是一种有前途的生物燃料生产原料。然而，所面临的挑战包括与典型的木质纤维素预处理相关的环境和/或财务成本，所述木质纤维素预处理需要在转化为生物燃料之前克服材料的天然可降解性。厌氧真菌是属于早期分化的新美鞭菌门（Neocallimastigomycota）的一组未被探索的微生物，并且原生于哺乳动物复杂进化的食草动物消化系统。厌氧真菌由于其高效水解木质纤维素的能力和将这种底物转化为H2和乙醇的能力的组合，在生物燃料生产过程中具有很好的应用潜力。此外，它们可以产生挥发性脂肪酸前体，用于随后通过其他微生物生物转化为H2或CH 4。它们的自然栖息地的复杂的生物学特性进行了描述，这些功能的背景下，对合适的工业系统的体外生长的发展。此外，还从工艺和基因工程的角度审查了实现这一目标的进展情况。此外，提出了新的机会，利用厌氧真菌木质纤维素预处理;暗发酵;生物乙醇生产;和潜在的整合与产甲烷，微生物电解池和光发酵。
Lignocellulose is a promising feedstock for biofuel production as a renewable, carbohydrate-rich and globally abundant source of biomass. However, challenges faced include environmental and/or financial costs associated with typical lignocellulose pretreatments needed to overcome the natural recalcitrance of the material before conversion to biofuel. Anaerobic fungi are a group of underexplored microorganisms belonging to the early diverging phylum Neocallimastigomycota and are native to the intricately evolved digestive system of mammalian herbivores. Anaerobic fungi have promising potential for application in biofuel production processes due to the combination of their highly effective ability to hydrolyse lignocellulose and capability to convert this substrate to H2 and ethanol. Furthermore, they can produce volatile fatty acid precursors for subsequent biological conversion to H2 or CH4 by other microorganisms. The complex biological characteristics of their natural habitat are described, and these features are contextualised towards the development of suitable industrial systems for in vitro growth. Moreover, progress towards achieving that goal is reviewed in terms of process and genetic engineering. In addition, emerging opportunities are presented for the use of anaerobic fungi for lignocellulose pretreatment; dark fermentation; bioethanol production; and the potential for integration with methanogenesis, microbial electrolysis cells and photofermentation.
