We're really just understanding the complex world of microbes that exist on and in corals. The more we learn, the more there is to learn! Many of the bacteria, viruses, and fungi that we've found serve useful purposes in the coral microbiome. Once we figure out what they're doing, we can start to hand craft probiotics to solve problems like temperature related coral bleaching or even the toxins released in an oil spill.

This video presents the basics of what we know, and how we're planning on using that knowledge to help save the world's coral reefs. What we can use on a wild reef, we can also use in our reef tanks - so this is research worth paying attention to! Acropora or other SPS corals suffering from RTN/STN could one day be treatable directly - we might not need to frag a coral anymore in a few years to save it from the advancing infection.

Abstract
The use of Beneficial Microorganisms for Corals (BMCs) has been proposed recently as a tool for the improvement of coral health, with knowledge in this research topic advancing rapidly. BMCs are defined as consortia of microorganisms that contribute to coral health through mechanisms that include (a) promoting coral nutrition and growth, (b) mitigating stress and impacts of toxic compounds, (c) deterring pathogens, and (d) benefiting early life-stage development. Here, we review the current proposed BMC approach and outline the studies that have proven its potential to increase coral resilience to stress. We revisit and expand the list of putative beneficial microorganisms associated with corals and their proposed mechanisms that facilitate improved host performance. Further, we discuss the caveats and bottlenecks affecting the efficacy of BMCs and close by focusing on the next steps to facilitate application at larger scales that can improve outcomes for corals and reefs globally.
