Lignocellulosic biomass is an important feedstock for a potential future bio-based economy. Owing to its compact structure, suitable decomposition technologies will be necessary to make it accessible for biotechnological conversion. While chemical and enzymatic hydrolysis are currently established methods, a promising alternative is provided by fast pyrolysis. The main resulting product thereof, referred to as pyrolysis oil, is an energy-rich and easily transportable liquid. Many of the identified constituents of pyrolysis oil, however, have previously been reported to display adverse effects on microbial growth. In this Opinion we discuss relevant biological, biotechnological, and technological challenges that need to be addressed to establish pyrolysis oil as a reliable microbial feedstock for a bio-based economy of the future.
木质纤维素生物质是未来生物基经济的重要原料。由于其结构紧凑，为了使其能够进行生物技术转化，需要合适的分解技术。虽然化学和酶解是目前已建立的方法，但快速热解提供了一种很有前途的替代方法。其主要的产物，称为热解油，是一种能量丰富且易于运输的液体。然而，已鉴定的热解油的许多成分以前曾被报道对微生物的生长有不利影响。在本观点中，我们讨论了相关的生物学、生物技术和技术挑战，这些挑战需要得到解决，以使热解油成为未来生物基经济中可靠的微生物原料。
