Coleção de microalgas de ambientes dulciaquícolas naturais da Bahia, Brasil, como potencial fonte para a produção de biocombustíveis: Uma abordagem taxonômica

Abstract

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 morpho- logical 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 Nägeli, Des- modesmus brasiliensis (Bohl.) Hegew, Scenedesmum obliquus (Turpin) Kütz, Ankistrodesmus falcatus (Corda) Ralfs, Ankistrodesmus fusiformis Corda, Kirchneriella lunaris (Kirchner.) Möbius, Pseudokirchneriella subcapitata (Korshi- kov) F. Hindák), three Trebouxiophyceae (Botryococcus braunii Kütz., Botryococcus terribilis Komárek et Marvan and Chlorella vulgaris Beijerinck), one Bacillariophyceae (Nitzschia sp.) and one Cyanobacteria (Synechocystis sp.).
