Abstract

The wide polarity range and highly polar compounds of two selected red seaweed, Grateloupia turuturu and Palmaria palmata were extracted using two different types of solvent, dichloromethane/methanol and methanol/water. Monthly in vitro antibacterial activities were studied using the microplate method against the marine bacteria Vibrio harveyi strain ORM4, known to infect abalone. Inhibition, slowdown and delay of Vibrio harveyi growth were investigated. Polar compounds of seaweed showed an activity against the abalone pathogen. The best activity was recorded from P. palmata collected in spring, with an inhibition of 7.9% of the bacterial growth. Preliminary 1H NMR profiles identified the differences between the extracts.
