絮凝微生物采收微藻的作用机制研究进展

微藻广泛分布于自然界,其易培养,生长快且应用价值高,普遍用于生物燃料、医学原料、优质食品源及畜牧养殖业等。近年来,通过对光生物反应器改造设计、高产藻株筛选、代谢通路基因改造等方法实现微藻产量的提高,而在微藻处理的下游过程的研究与创新不足,特别是微藻采收已经成为其产业发展的瓶颈。本文综述了絮凝法在微藻采收中的作用,重点讨论了絮凝微生物在微藻采收中的作用,并对絮凝微生物对微藻的絮凝机制进行广泛探讨,为絮凝微生物采收微藻提供理论依据。

Research progress on the function and mechanism of flocculating microorganisms in harvesting microalgal biomass

Microalgae are widely distributed in nature, which are easy to culture, grow fast and have high application value. They are widely used in biofuels, medical raw materials, high-quality food sources and animal husbandry. In recent years, the production of microalgae has been improved by the modification of photo-bioreactor, the screening of high yield algae and the transformation of metabolic pathway genes, and the research and innovation in the downstream process of microalgae treatment are not enough, especially the harvest of microalgae biomass has become the bottleneck of its industrial development. This paper summarizes the function of flocculation on the harvest of microalgal biomass, focus on the flocculation activity of flocculating microorganisms to harvest algal biomass, and the flocculation mechanism of flocculating microorganisms on microalgae is also discussed, Hopefully, it will provide some useful information and guidelines for the harvest of microalgal biomass by flocculating microorganisms.
