Description 578-582
In the present study, 25 bacterial isolates
were recovered from fouling samples collected from Parangipettai coastal area.
Based on their adherence property, three isolates were characterized and
identified as Bacillus sp.
(BB11), Serratia sp. (BB13) and Alteromonas sp. (BB14).
Six out of 20 actinomycete extracts showed inhibition of biofouling bacteria in
disc diffusion method. Strain R1 extract showed maximum inhibition against all
the biofouling bacteria tested. Culture filtrate and ethyl acetate extract from
strain R1 showed 13-15 mm inhibition against biofouling bacteria. Reduction in
biofilm formation was also observed in cover slip method. Active antifouling
compound was purified using TLC and detected by bioautography. Based on
chemical screening, the active compound was tentatively identified as sugar
containing molecule. potential actinomycete strain R1 was characterized and
identified as Streptomyces filamentosus (R1). Present study concluded that the marine actinomycete, Streptomyces filamentosus (R1) will be a
potential source for the development of eco-friendly antifouling compounds. This
will be a better alternative to the pollution causing synthetic antifoulants.
