“…Algae biomass in the surface water is closely associated with the concentration of COD Mn , which is considered to be one of the representative of organic pollutants [58]. It is reported that algae biomass would increase with the increase of COD Mn concentration within a certain range [59]. As expected, significant positive correlation (r = 0.949, p<0.01) was obtained between the COD Mn concentrations and the algae biomass.…”

Based on the monitoring data of conventional water quality in Qingshan Reservoir from 2018 to 2019, principal component analysis (PCA) and comprehensive nutritional status index (TLI) are used to evaluate water quality, planktonic algal communities, and eutrophication degree of Qingshan reservoir. The results showed that: 1) from 2018 to 2019, the annual average TLI is 56.54, indicating that the reservoir is in a slightly eutrophic state, which is conducive to algae growth; 2) the water quality of Qingshan Reservoir has obvious temporal and spatial variability: the water environment quality commonly decreased in the order winter>spring>autumn>summer, and exit zone>buffer zone>entry zone; meanwhile, the algal biomass in summer and autumn was significantly higher than that in spring and winter, and most of the algae were concentrated in the surface water except in January and decreased with the increase of depth; And related to the water quality environment, the biomass of cyanobacteria and green algae in Qingshan Reservoir is relatively high in summer, while diatom is the dominant species in spring and winter. We come to the conclusion that targeting at region and time will be more effective for the treatment of reservoir eutrophication.

Microalgal-bacterial consortium is an effective way to meet increasingly stringent standards in wastewater treatment. However, the mechanism of wastewater removal effect has not been properly explained in community structure by phycosphere. And little is known about that the concept of macroecology was introduced into phycosphere to explain the phenomenon. In the study, the algal–bacterial consortia with different ratios of algae and sludge were cultured in same aerobic wastewater within 48 h in photobioreactors (PSBRs). Community structure at start and end was texted by metagenomic analysis. Bray–Curtis similarities analysis based on microbial community showed that there was obvious convergent succession in all consortia, which is well known as “convergence” in macroecology. The result showed that Bray–Curtis similarities at End (overall above 0.88) were higher than these at Start (almost less than 0.66). In terms of community structure, the consortium with 5:1 ratio at Start are the more similar with the consortia at End by which the maximum removal of total dissolved nitrogen (TDN, 73.69%), total dissolved phosphorus (TDP, 94.40%) and NH3-N (93.26%) in wastewater treatment process and biomass production (98.2%) higher than other consortia, according with climax community in macroecology with the highest resource utilization than other communities. Therefore, the macroecology can be introduced into phycosphere to explain the consortium for advanced wastewater treatment and optimization community structure. And the study revealed a novel insight into treatment effect and community structure of algal–bacterial consortia for advanced wastewater treatment, a new idea for to shortening the culture time of consortium and optimize predicting their ecological community structure and predicting ecological community.

“…However, algal biofilms process can solve it. Zhang et al (2020) use membrane aeration to promote the efficiency of algae absorbing inorganic carbon. Besides, Schnurr et al (2016) found the growth of algae in algal biofilms increased with CO 2 concentration from 0.04% to 2%.…”

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.
