Nitrogen Starvation of Assessment in the Production of Single Cell Oils and Biodiesel Quality in Heterotrophic Cultures of Cyanobacteria Phormidium autumnale
Author(s): Erika Cristina Francisco*, Eduardo Jacob-Lopes, Karem Rodrigues Vieira and Telma Teixeira Franco
The cyanobacteria have great potential for aquaculture industries, bioproducts, bioenergy and bioremediation, as in the reduction of ammonia, phosphorus and organic compounds. The manipulation of the medium and the modes of operation of the cultures are necessary to induce the production of biomass and bioproducts, such as lipids. The aim of the study was to evaluate the different nitrogen sources and their depletion in heterotrophic cultures of the cyanobacterium Phormidium autumnale aimed at obtaining high yields lipid. The heterotrophic cultures were carried out in bubble column bioreactor employing cassava starch as organic carbon source. In the first stage, were studied different nitrogen source under the C/N (carbon/nitrogen) ratios in the culture medium of 20, 40 and 60. In the second stage, selected to nitrogen source with the greatest potential for the production of lipids an.. View more»
