Copper effects on biomarkers associated with photosynthesis, oxidative status and calcification in the Brazilian coral Mussismilia harttii (Scleractinia, Mussidae).

Seawater contamination with metals, such as copper (Cu), is a notable local impact threatening coral reefs. Cu effects on biomarkers associated with photosynthesis, oxidative status and calcification were evaluated in the Brazilian coral Mussismilia harttii using a marine mesocosm facility. Polyps were kept under control conditions (1.

Impact of oil spills on coral reefs can be reduced by bioremediation using probiotic microbiota.

Several anthropogenic factors, including contamination by oil spills, constitute a threat to coral reef health. Current methodologies to remediate polluted marine environments are based on the use of chemical dispersants; however, these can be toxic to the coral holobiont. In this study, a probiotic bacterial consortium was produced from the coral Mussismilia harttii and was trained to degrade water-soluble oil fractions (WSFs).
