Artificial algal blooms could remove atmospheric carbon — but can they be used responsibly?

Adding iron to the ocean to stimulate carbon-absorbing phytoplankton could have ecological consequences that reach far beyond the intervention site.

Influence of heterotrophs on phage infection of marine picocyanobacteria | mSystems

This study uncovers a previously unrecognized role of heterotrophic bacteria in shaping phage infection outcomes in marine cyanobacteria. Our findings demonstrate that the presence of heterotrophs can enable Prochlorococcus to recover from phage infection, irrespective of phage:host or heterotroph:host ratios. In contrast, Synechococcus exhibited variable outcomes, suggesting that the impact of heterotrophs is dependent on the heterotroph-host pairing. Recovery after phage infection appears to be driven by heterotroph-facilitated mitigation of oxidative stress and provision of organic carbon, which may alter host metabolism and contribute to protection against future phage infection. These results highlight the importance of the microbial community, particularly heterotrophs, in shaping cyanobacteria-phage dynamics and highlight the need to reframe host-phage interactions within a broader ecological framework.
