Bacteria living in marine sponge produce toxic compounds found in man-made products

Researchers have discovered for the first time that a common marine sponge hosts bacteria that specialize in the production of toxic compounds nearly identical to man-made fire retardants, a finding that could help scientists better understand the human health implications of these common additives.

The new findings, by scientists at the Scripps Institution of Oceanography (SIO) at the University of California, San Diego, moved the research team a step closer to unraveling the mysteries of this powerful group of chemical compounds, known as polybrominated diphenyl ethers (PBDEs).

The National Science Foundation's (NSF) Division of Ocean Sciences and the National Institute of Environmental Health Sciences (NIEHS) of the National Institutes of Health jointly funded the research through SIO's Center for Oceans and Human Health.

"For many years scientists have been finding clues that suggested nature was making these compounds," said SIO marine chemist Brad Moore, a senior author of the study. "Now that we understand how they are produced in the marine environment, we are exploring why they exist, and the human health concerns associated with them."
