A TEAM of scientists at the Fisheries College and Research Institute (FCRI) at Thoothukudi has successfully extracted bio-fuel from marine micro algae. The extraction of bio-fuel by standardising the research procedure from marine micro algae is a major breakthrough and the FCRI has planned to develop an industrial model for mass production of bio-fuel from marine micro algae, said institute dean V K Venkataramani. The marine micro algae, isolated from sea water, was first cultivated under autotrophic and heterotrophic culture systems using transestrification method, a process of conversion of an organic ''acidester'' into another ''ester'' of the same acid.
