| Marine natural products isolated from the sponge Fascaplysinopsis cf reticulata, in French Polynesia, were investigated as an alternative to antibiotics to control pathogens in aquaculture. The overuse of antibiotics in aquaculture is largely considered to be an environmental pollution, because it supports the transfer of antibiotic resistance genes within the aquatic environment. One environmentally friendly alternative to antibiotics is the use of quorum sensing inhibitors (QSIs). Quorum sensing (QS) is a regulatory mechanism in bacteria which control virulence factors through the secretion of autoinducers (AIs), such as acyl-homoserine lactone (AHL) in gram-negative bacteria. Vibrio harveyi QS is controlled through three parallel pathways: HAI-1, AI-2,... |

| Forest fire is an important issue in New Caledonia. During the dry season, forest fire can remove vegetation from large areas (from 10 000 to 30 000 ha per year on average), leaving metal-rich soils uncover and more exposed to runoff. The impact of forest fires on the chemical and microbiological quality of water has been poorly studied in New Caledonia, either for river water bodies or coastal lagoon water bodies. The purpose of this document is to review the current knowledge on forest fires impacts on water quality that has been documented in the worldwide literature, a topic of increasing importance in the context of global warming. |
