Abstract

AbstractThe ability of polar (1:1 water/methanol) and non-polar (dichloromethane) extracts of macroalgae from Arraial do Cabo, RJ, Brazil, to inhibit quorum sensing (QS) was investigated. Before extraction, half of the algae were treated with 30% ethanol to kill and remove surface-associated bacteria. Twenty of 22 polar extracts inhibited the QS of the acyl homoserine lactone (AHL) producer and reporter
