Description Not Available
Among the diverse variety of red algae, Asparagopsis taxiformis constitutes one of the abundant
biomass in the Kollam coast (Southwest coast of India). Therefore, in the present study, A. taxiformis
was collected, extracted and fractionated using column chromatography. The individual fractions
were evaluated in vitro for their antifouling, anticyanobacterial, piscicidal and crustaceans toxicity
assays. The fraction eluted with 2:8, petroleum ether and ethyl acetate exhibited strong and broad
spectrum of bioactivity. In antifouling assay against Limnea truncatula, the active algal fraction
produced 80% of foot repellency at 150 mg/L whereas in anticyanobacterial assay, the active fraction
inhibited 100% growth of Trichodesmium sp. at 320 mg/L. The algal fraction showed higher
piscicidal effect at the level of 60 mg/L. The crustacean toxicity of the active fraction was also
evaluated to find compounds without toxicity in non target organisms, Penaeus monodon and
Macrobrachium rosenbergii. It was found that column fraction showed less toxicity against the non
target organisms. The chemical constituents of the active fraction were identified by means of
chromatographic systems such as TLC, reverse phase HPLC and GC-MS. The overall activity profile
envisages that the active column fraction of A. taxiformis might contain synergistic bioactive
metabolites that could be utilized for the control of fouling organisms, algal bloom and
herbivorous/predaceous fishes in aquaculture ponds.
