Anaerobic digestion is a promising technology as a renewable source of energy products, but these products have low economic value and process control is challenging. Identifying intermediates formed throughout the process could enhance understanding and offer opportunities for improved monitoring, control, and valorisation. In this review, intermediates present in the anaerobic digestion process are identified and discussed, including the following: volatile fatty acids, carboxylic acid, amino acids, furans, terpenes and phytochemicals. The key limitations associated with exploiting these intermediates are also addressed including challenging mixed cultures of microbiology, complex feedstocks, and difficult extraction and separation techniques.
厌氧消化是一种很有前途的可再生能源产品技术，但这些产品的经济价值较低，过程控制具有挑战性。确定整个过程中形成的中间产物可以增进理解，并为改进监测、控制和增值提供机会。在这篇综述中，确定并讨论了厌氧消化过程中的中间产物，包括挥发性脂肪酸、羧酸、氨基酸、呋喃、萜类化合物和植物化学物质。还讨论了利用这些中间产物的关键限制因素，包括微生物混合培养的挑战性、复杂的饲料以及困难的提取和分离技术。
