Abstract
Despite the large impact of environmental conditions on cyanobacterial blooms, their dynamics cannot be explained only by abiotic factors, so biotic drivers are considered to be critical. Cyanobacteria produce an extracellular mucilage or more commonly known as extracellular polymeric substances (EPS) creating a region known as the phycosphere. Various interactions and associations occur between cyanobacteria and specific other bacteria in the phycosphere. It is hypothesized that cyanobacteria-associated bacteria or epibionts have a fundamental impact on cyanobacterial growth. In addition, because of the wide range of cyanobacterial metabolic properties, including the synthesis of many secondary metabolites, various heterotrophic microorganisms benefit from association with cyanobacteria. Many studies have also reported antagonistic interactions between cyanobacteria and other bacteria. With these substantial interactions among cyanobacteria and associated bacteria, it is crucial to identify the diversity and metabolism of the entire microbial population within a water body in order to better understand the ecological processes that lead to the formation of cyanobacterial blooms in freshwater systems and their impact on water treatment processes. Hence, the this study explored the fundamental interactions between bloom-forming cyanobacteria and their associated bacteria in water and their impact on treatment processes (focus oxidation and BAC).
