|Title:||Third Generation Biodiesel Production From Microalgae [produção De Biodiesel De Terceira Geração A Partir De Microalgas]|
|Abstract:||The aim of the study was to evaluate the third generation biodiesel produced from heterotrophic cultivation of the microalgae Phormidium sp. employing cassava starch as source of organic carbon. An experimental design was performed to determine the optimal conditions of temperature and C/N ratio. From the best growing conditions, was developed cultivations in batch and fed-batch in a bioreactor and evaluated the biodiesel quality. The results indicate that the temperature of 30ºC and the C/N ratio of 68 are the ideal conditions of the process. The highest biomass productivity (50.41mgL−1h-1) and lipid productivity (7.49mgL−1h-1) were obtained in batch cultivations. The fatty acids most representative were caproic acid (65.29%) and oleic acid (23.88%). The fuel properties of biodiesel: ester content of 99.9%, cetane number of 54.88, iodine value of 21.47gI100g−1, unsaturation degree of 23.88% and a cold filter plugging point of 39.21ºC, comply with the main international and national standards.|
