Abstract: | It is now well known that many marine organisms use low-molecular volatile substances as signals, in order to coordinate activities
between different individuals. The study of such pheromones requires the isolation and enrichment of the secretions from undisturbed
living cells or organisms over extended periods of time. The Grob-Hersch extraction device, which we describe here, avoids
adverse factors for the biological materials such as strong water currents, rising gas bubbles or chemical solvents. Furthermore,
the formation of sea-water spray is greatly reduced. The application of this technique for the isolation of pheromones of
marine algae and animals is described. |
