Abstract

Microalgae offer an innovative solution for utilizing industrial waste to produce sustainable ruminant feed. With strong carbon capture capabilities, they play a vital role in biological carbon capture and utilization. Advances in biotechnology enable the use of industrial waste streams, offering a pathway to reducing carbon emissions and cultivation costs. Extensive research highlights microalgae’s nutritional and anti-methanogenic benefits for ruminants, yet they remain commercially unutilized in feed. To address cultivation limitations, this review explores advancements in algae carbon capture biotechnology and proposes brewery waste to support algae cultivation. In addition, the challenges and bottlenecks that remain to be overcome for future commercial translation of this strategy are presented. This review establishes a theoretical solution for integrating microalgae into high-emission industries like breweries and utilization of algae biomass to reduce agricultural emissions.

全细胞微藻：将工业废物转化为可持续反刍动物饲料的潜力

微藻为利用工业废物生产可持续的反刍动物饲料提供了一种创新的解决方案。它们具有较强的碳捕集能力，在生物碳捕集利用中起着至关重要的作用。生物技术的进步使利用工业废物流成为可能，为减少碳排放和种植成本提供了一条途径。广泛的研究强调了微藻对反刍动物的营养和抗甲烷作用，但它们在饲料中仍未被商业化利用。为了解决藻类培养的局限性，本文综述了藻类碳捕获生物技术的进展，并提出了啤酒废弃物支持藻类培养的建议。此外，还指出了该策略在未来的商业翻译中需要克服的挑战和瓶颈。本文为微藻融入啤酒等高排放产业和利用藻类生物量减少农业排放建立了理论解决方案。
