Extraíbles de cortezas chilenas: Efecto sobre la luminiscencia de bacterias
Abstract
Bioluminescence decrease of bacteria as a biological activity indicator for bark water extracts was determinate. Four Chilean barks were tested. A different reduction on bioluminescence depending on bark species was observed. Increasing time of thermal treatment of bark (24, 48, 72 and 144 hours with 103°C) produced a reduction of the biological activity of extracts. The study indicates that the terpenes could be responsible for the described effect.
