Inhibition of byssal formation in Semimy ... led substrata in northern Chile
Inhibition of byssal formation in Semimytilus algosus Gould, 1850 by a film-forming bacterium isolated from biofouled substrata in northern Chile
5387
Semimytilus algosus is a small mussel species that fouls artificial culture systems of the scallop Argopecten purpuratus (Lamarck, 1819) in the north of Chile. Since biofouling organisms are a serious problem in culture, competing with the scallops for food and oxygen, environmentally-friendly methods are required to mitigate the effects of this fouling in the culture systems. The present study reports the evaluation of the inhibitory effect of biofilms and extracellular products (EP) of the bacterium Alteromonas strain Ni1-LEM on the byssal formation of S. algosus juveniles. Laboratory bioassays were carried out to determine the reattachment, exploratory behaviour and/or byssal thread production of the mussel in plastic Petri dishes containing bacterial biofilms, different dilutions of EP, and EP incorporated in a test substratum. It was concluded from the results that culture supernatants of the Alteromonas tested had an inhibitory effect on reattachment by S. algosus.
