“…It should be noted that while many of these markers are shared between protists and metazoans undergoing cell death, PCD in metazoans is orchestrated and largely defined by the expression and activation of caspases, calcium-dependent proteases that cleave after aspartate residues. Homologous enzymes in phytoplankton, termed metacaspases, lack this specificity ( Minina et al, 2020 ), along with other critical features of caspases, calling into question the involvement of metacaspases in non-necrotic cell death pathways of phytoplankton (reviewed by Berges et al, 2022 ). In spite of the controversy surrounding the true function of metacaspases, several studies have used aspartate-containing substrates to identify caspase-like activity accompanying cell death of phytoplankton, often associated with an increase in metacaspase expression and other markers for PCD (e.g., Wang et al, 2017 ; Zhao et al, 2020 ).…”

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.
