Probiotics Prevented Coral Bleaching During Red Sea Heat Wave

Scientists discovered that administering probiotic treatments to corals prevented bleaching during a Red Sea heat wave in October 2026.

The treated corals maintained their photosynthetic efficiency and color while untreated corals suffered from bleaching and health decline.

Using genetic sequencing, researchers found that probiotic treatment altered the corals' microbiomes, increasing beneficial bacteria like Cobetia.

Different proviotic and postbiotic treatments provoked distinct metabolic responses in the corals, indicating multiple pathways for coral protection.

The study offers hope for coral reef conservation efforts as probiotics could provide a scalable solution to combat climate-induced bleaching.

Corals provide habitat for about one-third of marine species but are declining due to rising ocean temperatures and bleaching events.

This research contributes to growing scientific knowledge about interventions that can help coral reefs survive in warming oceans.
