摘要

欧洲对生物甲烷的需求不断增长，迫切需要开发可持续和具有成本效益的技术，以实现到2030年生产350亿立方米生物甲烷的宏伟目标。生物技术是一个很有前途的综合平台，可以净化沼气，使生物源二氧化碳增值，同时生产高价值的化学品。光合作用沼气升级已被证明是一个有吸引力的平台，因为微藻可以在产生生物质的同时固定二氧化碳，这些生物质可以进一步用于生物燃料、生物肥料或生物刺激素的生产。但其投资成本高，微藻生物量生产率低，限制了其商业化。最近，从橄榄厂废水中获得的纳米颗粒的补充已被证明是一种有前途的技术，可以提高生物质生产力，去除二氧化碳，以及系统的整体稳定性。本文综述了该可持续平台的发展趋势和未来展望，旨在开发用于沼气升级和高价值化合物生产的新型集成微藻生物精炼厂。

Exploring the future of photosynthetic biogas upgrading process

The increasing demand for biomethane in Europe requires the urgent development of sustainable and cost-effective technologies to meet the ambitious target of producing 35 bcm of biomethane by 2030. Biological technologies stand as a promising integrating platform to purify biogas and valorize biogenic CO₂, while producing high-value chemicals. Photosynthetic biogas upgrading has demonstrated to be an attractive platform as microalgae can fix CO₂ while producing biomass that can be further valorized for biofuel, biofertilizer or biostimulant production. However, its high investment cost and the low microalgae biomass productivities have limited commercialization. Recently, the supplementation of nanoparticles obtained from olive-mill wastewater, has demonstrated to be a promising technique to improve biomass productivity, CO₂ removals, and the overall stability of the system. This review summarizes the current trends and future outlooks of this sustainable platform aiming at the development of novel integrated microalgae biorefineries devoted to biogas upgrading and high-value compounds production.
