Although the production of biofuels from microalgae has numerous advantages over other raw materials, its large-scale application still comes across economic aspects. In this context, the concept of biorefinery emerges as a strategy to increase the sustainability of this process. Studies have been developed to reduce production costs, especially to optimize the harvesting stage. Among the techniques used, bioflocculation is a promising alternative to traditional harvesting methods, as it is viable in terms of cost, execution and efficiency and, above all, it is a more environmentally appropriate method. This study aimed to perform a bibliometric and systematic review of traditional algal harvesting techniques and the mechanisms governing the different interactions of microorganisms used as bioflocculants, especially fungi. The high efficiencies of microalgae harvesting, combined with the possibility of cultivation in wastewater and the various bioproducts originated from this biomass, show the potential application of bioflocculation in the context of integrated biorefineries.

尽管从微藻类生产生物燃料比其他原材料具有许多优势，但其大规模应用仍涉及经济方面。在这种情况下，生物炼制的概念应运而生，以提高其可持续性。已经进行了研究以降低生产成本，尤其是优化收获阶段。在所使用的技术中，生物絮凝是传统收割方法的一种有前途的替代方法，因为它在成本，执行和效率方面都是可行的，最重要的是，它是一种对环境更适合的方法。这项研究旨在对传统的藻类收获技术以及控制用作生物絮凝剂的微生物（尤其是真菌）的不同相互作用的机制进行文献计量和系统的综述。
