16S rRNA amplicon sequencing of corals exposed to ozone-produced oxidants (OPO)
Hard coral Stylophora pistillata and soft coral Xenia sp. were exposed to different levels of ozone-produced oxidants for 4 weeks. Physiological parameters, molecular biomarkers, and surface mucus layer microbiomes were monitored to assess the impact of ozone water treatment on coral holobionts. The study provides a first guideline for the safe application of ozone as a water treatment tool in marine RAS. It further evaluates ozone as a tool to deliberately modify host-associated microbiomes.
