Abstract

Indonesia as one of the world largest maritime country has very huge natural resources including microalgae. However, recently the analysis of potential local strain microalgae is still few to be studied. Whereas, the microalgae can be develop as biodiesel and an excellent solution to overcome the depletion of fossil fuel. This research was aimed to study microalgae species of local mix culture of microalgae isolated from Glagah and their lipid profile. The identification of microalgae species was done by observation under light microscope, while lipid profiling was done by measuring the lipid total using Nile Red Staining and the fatty acid profiling was done by using GC-MS method. Results showed that Glagah Consortium Microalgae was composed by six species microalgae including Cyclotella sp., Cylindrospermopsis sp., Golenkinia sp., Syracosphaera sp., Corethron sp., and Chlamydomonas sp. which could produce fatty acids suitable for biodiesel. The lipid content of the mix culture was 1.25% which composed by 51.27% SFA, 33.42% MUFA and 11.80% PUFA indicating that the mix culture of Glagah consortium was prospective as local biodiesel source.
