Acesso em: 26 abr. 2024.e- 2358-1697http://repositorio.bc.ufg.br//handle/ri/24613This work aimed to evaluate different species of microalgae isolated from marine and freshwater environments from the Northeast of Brazil in regarding to its capacity of biomass production and accumulation of esters. The research also has the intention of characterize the changes in the fatty acid profile of each species and its influence on the properties of the produced biodiesel. The development of the cultures was accompanied by cell counts and by "in vivo" fluorescence analyses and the fatty acid composition of biomass were determined by GC-MS. The results showed a potential use for biodiesel production in Pediastrum tetras, Scenedesmus acuminatus, Chlamydomonas sp., Lagerheimia longiseta, Amphora sp., Monoraphidium contortum, Chlorella sp. and Cosmarium sp. These species showed high biomass productivity -1 -1 -1 (0.28 – 0.95 g L-¹ d-¹) and contents of the ester higher than the soybean (229.6- 584.9 mg g-¹).porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/BiocombustíveisMicrorganismos fotossintetizantesPerfil de FAMEBiofuelsPhotosynthetic microorganismsFAME profileArtigo
