CONSORTIUM OF MICROALGAE FROM WALLACEAN WATERS, NUSA TENGGARA BARAT FOR BIODIESEL PRODUCTION

Abstract

  Abstract:Abundance and distribution of   oil-producing microalgae species  in  various waters  of Lombok islands, Indonesia have been observed. Microalga samples were collected based on a concentration method, using plankton net eyed nets 20 microns. Observations of samples, i.e.identifications and abundance calculations of each microalga species conducted at the Laboratory of Biology, Faculty of Mathematics and Natural Sciences, University of Mataram. The result showed that, in the community of marine microalgae from Lombok and Sumbawa Islands consist of 62 species of  potential producing-oil microalgae were dominated by Bacteriastrumdelicatulum, B. variance, Chaetocerosaffinis, C. liciniosum, C. lorenzianum, Gyrosigma sp., Oscillatoriasp., Pseudonitzschia spp., and Thalassionemanitzschicoides. Types of  oil-producing freshwater microalgae in Lombok Island consist of 19 species of potential producing-oil microalgae, identified with high abundance and dominance, covering Microcystis aeruginosa, M. incerta, Nostoc sp., and Pediastrumboryanum.  Key words: biodiesel,  microalgae, Wallacean waters, West Nusa Tenggara
