Using renewable microalgal biomass as active feedstocks for biofuels and bioproducts is explored to substitute petroleum-based fuels and chemicals. In the last few years, the importance of microalgae biomass has been realized as a renewable feedstock due to several positive attributes associated with it. Biorefinery via anaerobic digestion (AD) of microalgal biomass is a promising and sustainable method to produce value-added chemicals, edible products and biofuels. Microalgal biomass pretreatment is a significant process to enhance methane production by AD. Findings on the AD microbial community’s variety and organization can give novel in turn on digester steadiness and presentation. This review presents a vital study of the existing facts on the AD microbial community and AD production. Co-digestion of microalgal biomass with different co-substrates was used in AD to enhance biogas production, and the process was economically viable with improved biodegradability. Microcystins, which are produced by toxic cyanobacterial blooms, create a severe hazard to environmental health. Anaerobic biodegradation is an effective method to degrade the microcystins and convert into nontoxic products. However, for the cost-effective conversion of biomass to energy and other beneficial byproducts, additional highly developed research is still required for large-scale AD of microalgal biomass.

厌氧消化微藻生物质以生产生物能源、去除养分和微囊藻毒素：现状

探索使用可再生微藻生物质作为生物燃料和生物产品的活性原料来替代石油基燃料和化学品。在过去的几年中，由于与微藻生物质相关的几个积极属性，它作为可再生原料的重要性已被意识到。通过微藻生物质的厌氧消化 (AD) 进行生物精炼是生产增值化学品、食用产品和生物燃料的一种有前景且可持续的方法。微藻生物质预处理是通过 AD 提高甲烷产量的重要过程。AD 微生物群落的多样性和组织的发现可以反过来为消化器的稳定性和表现提供新的信息。本综述对 AD 微生物群落和 AD 生产的现有事实进行了重要研究。微藻生物质与不同共底物的共同消化被用于 AD 以提高沼气产量，并且该过程在经济上可行并提高了生物降解性。由有毒蓝藻大量繁殖产生的微囊藻毒素对环境健康造成严重危害。厌氧生物降解是降解微囊藻毒素并转化为无毒产物的有效方法。然而，为了将生物质经济地转化为能源和其他有益的副产品，还需要对微藻生物质的大规模 AD 进行额外的高度发达的研究。厌氧生物降解是降解微囊藻毒素并转化为无毒产物的有效方法。然而，为了将生物质经济地转化为能源和其他有益的副产品，还需要对微藻生物质的大规模 AD 进行额外的高度发达的研究。厌氧生物降解是降解微囊藻毒素并转化为无毒产物的有效方法。然而，为了将生物质经济地转化为能源和其他有益的副产品，还需要对微藻生物质的大规模 AD 进行额外的高度发达的研究。
