This is interesting and might be relevant for bloom-ending processes in #phytoplankton. Roseobacter can coexist with Emiliania huxleyi (and important bloom forming coccolithophore important to carbon cycling), providing vitamins for ready supplies of sugar and amino acids. However when an algal cell is dying they bacteria can collect additional compounds and leave in search other other hosts. #algae #oceanography

'Friend or foe' bacteria kill their algal hosts when coexisting is no longer beneficial
Scientists have detailed a lifestyle switch that occurs in marine bacteria, in which they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them. The results are published today in eLife.Science X (Phys.org)
