abstract：:The deep-sea hydrothermal vent shrimp Rimicaris exoculata largely depends on a dense epibiotic chemoautotrophic bacterial community within its enlarged cephalothoracic chamber. However, our understanding of shrimp-bacterium interactions is limited. In this report, we focused on the deltaproteobacterial epibiont of R. ...
