“…Recently, the rodophycean genus Gracilaria has grown in importance worldwide as an agar source owing to its abundance in biomass and successful cultivation (Critchley, 1993) . For example, Gracilaria lemaneiformis (Bory) Dawson is being grown commercially in Venezuela as a source of agar (Rincones, 1994) .
