Abstract

Abstract: The rise in living standards has generated a demand for higher aquatic environmental quality. The microalgal community and the surrounding organic molecules, environmental factors, and microorganisms, such as bacteria, are together defined as the phycosphere. The bacteria in the phycosphere can form consortia with microalgae through various forms of interaction. The study of the species in these consortia and their relative proportions is of great significance in determining the species and strains of stable algae that can be used in sewage treatment. This article summarizes the following topics: the interactions between microalgae and bacteria that are required to establish consortia; how symbiosis between algae and bacteria is established; microalgal competition with bacteria through inhibition and anti‐inhibition strategies; the influence of environmental factors on microalgal–bacterial aggregates, such as illumination conditions, pH, dissolved oxygen, temperature, and nutrient levels; the application of algal–bacterial aggregates to enhance biomass production and nutrient reuse; and techniques for studying the community structure and interactions of algal–bacterial consortia, such as microscopy, flow cytometry, and omics. Practitioner points: Community structures in microalgal–bacterial consortia in wastewater treatment. Interactions between algae and bacteria in wastewater treatment. Effects of ecological factors on the algal–bacterial community in wastewater treatment. Economically recycling resources from algal–bacterial consortia based on wastewater. Technologies for studying microalgal–bacterial consortia in wastewater treatment. Abstract : Consortia formed by Microalgae and bacteria interacting with each other are surrounded in their phycosphere that is a micro‐ecosystem with special structures and functions. Community Structures and Interactions are the key factors affecting the development of the phycosphere and the efficiency of wastewater treatment.
