“…The biological control of cyanobacteria by using algicidal bacteria is a promising approach in an aquatic environment [11,19]. The two bacteria we used have been verified to be able to have algicidal effects on the unicellular Microcystis of the same strain in a short time, which was in accordance with previous reports on other Microcystis strains [20][21][22]. P. stutzeri ZJ4 belongs to one of the top three genera in cyanobactericidal bacteria [6].…”

Algicidal bacteria combined with the ability of aerobic denitrification is considered to be a promising way to control harmful cyanobacterial bloom and remove nitrogen. However, the effect of these bacteria on the vertical distribution of colonial cyanobacteria and nutrients remained unknown. In this study, two algicidal and denitrifying bacteria were respectively co-cultured with the colonial Microcystis aeruginosa to construct the microcosm systems, and then the cyanobacteria number, the ratio of bacterial to cyanobacterial abundance, the content of dissolved nitrogen, phosphorus and organic carbon in different water layers were investigated. The results showed that the distribution difference of Microcystis among the vertical water layers was further enlarged due to the short-term influence of algicidal bacteria Brevundimonas diminuta and Pseudomonas stutzeri. The number of Microcystis in the lower layer was further reduced by the inhibitory effect of the algicidal bacteria. However, there was a dramatic increase in the number of Microcystis in the upper layer, even when the ratio of algicidal bacteria to cyanobacteria increased significantly. B. diminuta and P. stutzeri both greatly promoted the removal of dissolved total nitrogen in the upper and middle layers of cyanobacteria blooming water, but they also boosted the release of dissolved phosphorus in all layers. These results enable us to better understand the possible limitations of algicidal bacteria in their application to control cyanobacteria blooms.

“…Bacterial immobilization technology has been utilized in a wide range of disciplines to enhance bacterial activity in a number of applications, including wastewater treatment (e.g., Hou et al, 2020 , 2021 ), degradation of marine oil pollution (e.g., Li et al, 2021c ), and probiotic delivery (e.g., Dimitrellou et al, 2019 ; reviewed by Mettu et al, 2021 ). Algicidal bacteria have also been immobilized to various matrices for HAB mitigation ( Table 3 ), including immobilization in (polyvinyl alcohol-) sodium alginate (e.g., Su et al, 2017 ; Zhang et al, 2018 ; Wang and Coyne, 2020 ; Ouyang et al, 2021 ), cellulose sponge (e.g., Noh et al, 2017 ; Wang and Coyne, 2020 ), polyester (e.g., Wang and Coyne, 2020 ), polyurethane (e.g., Kang et al, 2007 ), agarose (e.g., Wang and Coyne, 2020 ), agar (e.g., Kang et al, 2007 ), and coconut fibers (e.g., He et al, 2021 ).…”

Interactions between bacteria and phytoplankton in aqueous ecosystems are both complex and dynamic, with associations that range from mutualism to parasitism. This review focuses on algicidal interactions, in which bacteria are capable of controlling algal growth through physical association or the production of algicidal compounds. While there is some evidence for bacterial control of algal growth in the field, our understanding of these interactions is largely based on laboratory culture experiments. Here, the range of these algicidal interactions is discussed, including specificity of bacterial control, mechanisms for activity, and insights into the chemical and biochemical analysis of these interactions. The development of algicidal bacteria or compounds derived from bacteria for control of harmful algal blooms is reviewed with a focus on environmentally friendly or sustainable methods of application. Potential avenues for future research and further development and application of bacterial algicides for the control of algal blooms are presented.

“…Proteobacteria, which is divided into five parts, is one of the most widespread and extensively studied bacteria in the microbiology field, and it is well known to effectively biodegrade cyanobacteria and diatoms in eutrophic environments [2,10]. The majority have been identified as members of Pseudomonas [18,19], Aeromonas [20,21], Acinetobacter [22], Raoultella [23], Brevundimonas [24], Ochrobactrum [25], Halobacillus [26], Shewanella [27], Citrobacter [28], Stenotrophomonas [29], Serratia [30] and Hahella [31] genera belonging to the γ-Proteobacteria class.…”

“…As the Brevundimonas sp. AA06 is immobilized using polyvinyl alcohol-sodium alginate beads and B. methylotrophicus ZJU is immobilized with Fe 3 O4 nanoparticles, the inhibition effects are much better than freely suspended cells [24,50]; meanwhile, the extracellular polymeric substances produced by P. aeruginosa ZJU1 are made as bioflocculants, and the removal efficiency of M. aeruginosa reached 100 ± 0.07% in 5 min at the dosage of 2.75 g/L bioflocculant [130]. These strategies demonstrating the "indirect attack" of microorganisms could be immobilized by multi-functional systems and their anticyanobacterial products could be further enriched.…”

Harmful algal blooms (HABs) have attracted great attention around the world due to the numerous negative effects such as algal organic matters and cyanobacterial toxins in drinking water treatments. As an economic and environmentally friendly technology, microorganisms have been widely used for pollution control and remediation, especially in the inhibition/biodegradation of the toxic cyanobacterium Microcystis aeruginosa in eutrophic water; moreover, some certain anticyanobacterial microorganisms can degrade microcystins at the same time. Therefore, this review aims to provide information regarding the current status of M. aeruginosa inhibition/biodegradation microorganisms and the acute toxicities of anticyanobacterial substances secreted by microorganisms. Based on the available literature, the anticyanobacterial modes and mechanisms, as well as the in situ application of anticyanobacterial microorganisms are elucidated in this review. This review aims to enhance understanding the anticyanobacterial microorganisms and provides a rational approach towards the future applications.
