“…They span a range of modes with mutualistic symbiosis on one side of this strategic spectrum, where each species benefits (reviewed by Cooper and Smith, 2015 ), to the opposite side of the spectrum in which pathogenic or algicidal bacteria lyse algae for access to their intracellular contents. These complex inter-kingdom relationships can fluctuate with changes in their physical and chemical environment, and are often mediated by species composition and abundance ( Zhang et al, 2021c ).…”

Algicidal Bacteria: A Review of Current Knowledge and Applications to Control Harmful Algal Blooms

2022

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.

“…PCC7002 cell density was adjusted to ∼10 7 cells ml –1 , and extra Halomonas sp. isolated above was co-inoculated in Syn B culture to the density of ∼10 6 cells ml –1 ( Zhang et al, 2021 ). Before inoculating to the Syn culture, the bacteria was pre-cultured 2 days in marine broth 2216 at 33°C and washed twice with the modified A + medium.…”

Synechococcus is one group of main primary producers and plays a key role in oceanic carbon fixation and transformation. To explore how the temperature rise affects the bioavailability of Synechococcus-derived dissolved organic matter (SOM) and whether this effect would be altered by the involvement of heterotrophic bacteria, we compared the optical and molecular properties of the SOM of axenic Synechococcus sp. PCC7002 culture (Syn) to that with associated heterotrophic bacteria (SynB) under 15, 18, and 21°C growth temperatures at exponential and decay growth phases. Our results showed that the temperature rise increased the bioavailability of the SOM of both Syn and SynB cultures by lowering the proportion of the hydrogen-poor and double-bond structure-rich humus-like components and highly unsaturated substances, as indicated by the increase of spectral slope ratio (SR) and biological index (BIX) and decrease of humification index (HIX). Moreover, the involvement of heterotrophic bacteria modified the Synechococcus-derived SOM, together with its intracellular dissolved organic matter (DOM) excludes, lowering the SOM bioavailability. Our results indicated that the warming in climate change scenario may enhance the bioavailability of the Synechococcus-derived SOM although it may be tempered by the involvement of heterotrophic bacteria, providing an insight for preservation of the organic carbon pool in global oceans.

“…Cyanobacteria, the oldest oxygenic photosynthetic organism, is the fundamental primary producer together with eukaryotic algae in aquatic environments and is a major contributor to the global carbon, sulfur, and nitrogen cycles ( 1 , 2 ). Although cyanobacteria also belong to prokaryotic bacteria like heterotrophic bacteria, owing to their photosynthetic characteristics, they can coexist with diverse heterotrophic bacteria using a variety of interactions, like eukaryotic algae ( 3 – 5 ). Cyanobacteria primarily provide heterotrophic bacteria with carbon sources, and heterotrophic bacteria benefit the growth of cyanobacteria through various interactions ( 6 , 7 ).…”

“…Cyanobacteria primarily provide heterotrophic bacteria with carbon sources, and heterotrophic bacteria benefit the growth of cyanobacteria through various interactions ( 6 , 7 ). To date, interactions between oligotrophic marine cyanobacteria such as Synechococcus and Prochlorococcus and heterotrophic bacteria have been extensively studied ( 5 , 8 ).…”
