Coral reefs are under assault from multiple directions: increasing ocean acidification that threatens to slowly weaken and dissolve their calcium carbonate exoskeletons, rising temperatures that cause them to expel their beneficial algal partners and the high prevalence of coral diseases.

Coral probiotics can help reduce loss of coral. Of course, when most of us hear about probiotics, we think about a supplement or gut health. Indeed, the same principles can be applied to coral reefs.

Probiotics are one solution in the realm of microbial engineering, which has been applied to increase food security in agriculture and treat human diseases in medicine. Microbial engineering is experimental manipulation of individual microbes, microbial communities or their hosts. Scientists use various tools including 1) artificial selection on the host-microbiome system, 2) inoculating the host with beneficial microbes (also known as a probiotic) or 3) genetically-engineering specific microbial strains. Occasionally, a mix of these approaches is used.

There are 100 to 1000 times more bacteria on the surface of coral compared to the same area of human skin. Therefore, microbiome engineering will be an important management solution to ensure the future of coral reefs. A new review from ecologists in Australia outlines the use of microbiome engineering for coral reefs, including past successes and future directions. Here are three ways microbiome engineering can help save coral reefs:

1. Protect corals from disease.

The distinctively red bacteria Serratia marcescens infects humans, generally via hospital-acquired infections of patients with weak immune systems. Surprisingly, it also infects corals. A necrotizing coral pathogen, S. marcescens forms a biofilm that disrupts the normal mucus layer on corals. Scientists found that they could stop communication between S. marcescens bacteria by applying a beneficial bacterial cocktail. This probiotic was able to stop the progression of the disease by maintaining the antimicrobial properties of healthy coral mucus. Although it was tested on anemones, this method holds promise for other Cnidarians, like coral.

2. Enhance tolerance to environmental stress, such as rising ocean temperatures and oil spills.

Coral reefs attract millions of divers to board planes for the opportunity to visit the reefs of Southeast Asia, the Caribbean, and other beach paradises. Unfortunately, plane flights are one of the greatest carbon dioxide sources. The same plane flights that bring divers to beautiful underwater vistas also contribute to rising ocean temperatures. When it’s too warm for corals, they expel their beneficial algae partners, which provide 90% of their energy. This leads to coral bleaching which severely threatens the corals (and makes for a much less exciting and sad diving experience). Researchers started to inoculate corals with heat-tolerant algae from “donor” corals that can tolerate warmer temperatures. Results are promising, but more long-term studies are required to confirm this method would be successful in the long run.

Oil pollution is often associated with the death of wildlife along beaches, but it can also destroy reefs. Researchers inoculated corals with a mix of bacteria known to break down water-soluble oils. The probiotic reduced damage to corals from oil exposure.

3. Improve overall coral health.

Much like breeding crops with higher yields or crops perform best under suboptimal conditions, we can also harness the coral microbiome to improve their overall health. A coral’s microbiome can help it adapt to new environmental conditions faster compared to solely relying on evolution of its own genes. Both direct and indirect selection on the coral microbiome could help researchers find other solutions for coral health. Direct selection involves identifying the specific beneficial microbes, then creating a probiotic that can be applied to corals to improve their fitness. Scientists use indirect selection in a controlled setting to add artificial environmental stress (like heat) to corals in the lab. They keep the survivors and repeat the process. They inoculate corals with tissues from the lab. This method is more cost-effective and does not require specific knowledge of which microbes are conferring benefits.

Inoculating coral reefs with additional symbiotic algae could be used to protect against thermal stress. Probiotics can help with stopping necrotizing coral disease. Phage therapy has also been suggested to remove harmful bacteria and pathogens from the surface of coral. The role of fungi is still currently unknown, though they are present as part of the coral microbiome. Coral microbiome engineering is still in its early stages, but shows promise to be just as effective as microbiome engineering used in medicine to treat gut disorders and agriculture to improve food security.
