Bioactive Cembranoid Composition in the Soft Coral of Sarcophyton glaccum on The Response to Changing pH
Soft coral is predicted to outcompete with hard coral in future ocean acidification scenarios. Beside the biological resilience shown in acidic conditions, soft corals ability to maintain or compete for space is shown to relate with their ability to produce cytotoxic cembranoid-type compounds.
