Collection of microalgae from natural freshwater environments of Bahia, Brazil, as a potential source for biofuel production: a taxonomic approach

This study identified native species of microalgae (maintained at LABIOMAR/IB/UFBA Collection of Freshwater Microalgae) to indicate their potential to supply the biofuel production chain. Samples were collected in freshwater ecosystems around Salvador, Bahia, Brazil. Species identification was based in morphological characteristics.  Nineteen species were isolated and identified, 12 at the level of species and nine at the level of genus: 14 Chlorophyceae (Chlamydomonas sp1, Chlamydomonas sp2, Chlamydomonas sp3, Chlamydocapsa bacillus (Teiling) Fott, Chlorococcum sp1, Chlorococcum sp2, Coelastrum indicum Turn. Coelastrum microporum Nageli, Desmodesmus brasiliensis (Bohl.) Hegew, Scenedesmum obliquus (Turpin) Kutz, Ankistrodesmus falcatus (Corda) Ralfs, Ankistrodesmus fusiformis Corda, Kirchneriella lunaris (Kirchner.) Mobius, Pseudokirchneriella subcapitata (Korshikov) F. Hindak), three Trebouxiophyceae (Botryococcus braunii Kutz., Botryococcus terribilis Komarek et Marvan and Chlorella vulgaris Beijerinck), one Bacillariophyceae (Nitzschia sp.) and one Cyanobacteria (Synechocystis sp.).
