That was Alex Collins Reporting and for more on this story, just search for People Fixing the World, wherever you get your BBC podcasts.

Probiotics have long been all the range in health advice, but now scientists have also discovered they could be good for corals.

Erica Santoro is a microbiologist turned ecologist.

She's been testing a probiotic treatment on reefs in the Red Sea.

She's been speaking to my colleague Roland Pease.

Every single organism on the planet hosts uh bacteria and other microorganisms.

This is not different in the ocean as well.

So the corals also host a big amount of bacteria and microalgae.

So it is a big mix and soup of other microorganisms that live together with these coral hosts.

So we call these a holobiode because they actually work together and evolve together.

Together as well.

The thing that happens when there is any uh stress, like uh the temperatures are raising in the ocean, there's a trigger uh which like causes a lot of stress uh in the microalgae.

They produce a lot of compounds that are stressful for everybody, including the coral hose.

And uh, a couple of uh processes can happen there that uh these algae can be expelled.

by the host, that they can escape, uh the cell can just like break apart and like a this mutualistic relationship, they just break up.

Yes, so the idea here is we look at the coral and try to understand the beneficial uh relationships that exist between the coral and the microorganisms, and we isolate and manipulate those beneficial ones.

Currently, we are doing uh this in the ocean.

So we are upscaling from the lab setups and bringing to the field.

We culture those beneficial cells, we increase them in number and put them in some syringes and apply on top of the coral.

So this is gonna create kind of a cloud uh of beneficial bacteria on top of those colonies, and we apply these often, so we guarantee that's.
