Industry, agriculture, and residential areas generate increasing volumes of waste streams enriched with organic pollutants. Without proper treatment, they threaten the environment, but can be valorized with suitable microalgal biotechnologies. Although their development has a long history, recent years are marked with a boom of research in this field. This trend is fueled by the transition to circular bioeconomy gaining momentum all over the world. Current trends include the conversion of nutrients, including organics, nitrogen, and especially phosphorus from waste streams to environmentally friendly biofertilizer, detoxication of dangerous xenobiotics (pesticides and antibiotics), as well as the implementation of advanced omics methods for monitoring of treatment and designing of robust algal–bacterial consortia. Here, we review the recent developments highlighting the trends mentioned above.

工业，农业和居民区产生越来越多的富含有机污染物的废物流。如果没有适当的处理，它们会威胁环境，但是可以通过合适的微藻生物技术进行增值。尽管它们的发展历史悠久，但近年来在该领域的研究蓬勃发展。全球范围内向循环生物经济过渡的势头推动了这一趋势。当前的趋势包括将营养成分（包括有机物，氮，尤其是磷）从废物流转化为环保型生物肥料，对危险的异质生物（农药和抗生素）进行脱毒，以及实施先进的组学方法以监测治疗和设计药物健壮的藻菌联合体。这里，
