Coral reef survival is inclined on good bacteria

You might never know that some bacteria do save lives and it is being proved again by some good bacteria who keeps coral healthy that can able to withstand the impacts of global warming and also secure long term survival of reefs worldwide. A research published recently in the journal Science gives an overview of bacterial communities inhabiting on corals.

"Healthy corals interact with complex communities of beneficial microbes or 'good bacteria'," says Dr. Tracy Ainsworth from the ARC Centre of Excellence for Coral Reef Studies at James Cook University who led the study. "It is very likely that these microorganisms play a pivotal role in the capacity of coral to recover from bouts of bleaching caused by rising temperatures."

"Facilitating coral survival and promoting coral recovery are growing areas of research for coral reef scientists," says co-author Dr. Ruth Gates from Hawai'i Institute of Marine Biology, University of Hawai'i. "To do this we need to explore and understand the bacteria that help keep corals and coral reefs healthy."

Researchers have identified new directions that will help in understanding coral survival in rapidly changing reef environments.

"We know that lasting changes to the community of beneficial bacteria affects important aspects of the function of host organisms such as humans or corals, including their ability to withstand further stress," says Dr. Ainsworth.

The research holds importance in understanding the relationship of good bacteria and corals for a long time survival. It holds the research advancement to understand the complexity of coral’s genetic makeup and the bacterial communities that corals maintain on them.

"Preventing physical contact with corals and maintaining high water quality on reefs during stress events will reduce stress loads on corals and creates the best case scenario for survival and recovery," says Dr. Gates.
