The Marine Microbiomes lab focuses on the symbiotic relationships between marine hosts and their associated microbiomes. Read more
15 August, 2021Probiotics for corals boost resilience, help prevent mortality
As more coral reefs around the world suffer from bleaching and mass mortality due to warming ocean temperatures and related climate change conditions, good news about reefs is welcome news. A new study, Coral microbiome manipulation elicits metabolic and genetic restructuring to mitigate heat stress and evade mortality, shows probiotics to be helpful protagonists in boosting coral health and preventing mortality in the face of environmental stressors. Lead authors from King Abdullah University of Science and Technology (KAUST) are Dr. Raquel S. Peixoto, associate professor, Dr. Erika P. Santoro, postdoctoral fellow, and Dr. Helena D. M. Villela, research scientist.
13 August, 2021Corals survive the heat with bacterial help
Treating corals with a probiotic cocktail of beneficial bacteria increases survival after a bleaching event, according to new research. This approach could be administered in advance of a predicted heatwave to help corals recover from high sea temperatures.
Climate change is increasing the temperatures of the oceans, which disrupts the relationship between corals and their symbiotic photosynthetic algae and causes corals to bleach, in some cases eventually leading to their death. KAUST researchers have proposed that manipulating the coral microbiome might enhance their stress tolerance by using beneficial microorganisms for corals, or BMC.
