Isolation, Characterization of Algae and Production of Biodiesel

Algae sample was collected from a pond and was indentified as Spirogyra spp. It was grown in BG11 media in the required conditions. The algae was dried, powdered and used for further extraction processes. The lipid content was 16%, carbohydrate 50 mg/ml and protein 7.5 mg/ml. Algae oil was extracted from Spirogyra spp. to compare their conversion into biodiesel. The acid value of fats was estimated to be 7.17. It was transesterified and conversion percentage was found to be 88.9%.The obtained crude biodiesel was purified and purity of biodiesel was checked using Fourier Transform Infrared Spectrometer. Biodiesel as a fuel not only helps reducing the pollution, it also reduces health hazards and gives our society – A CLEANER AND GREENER TOMMOROW.
