| Abstract |
The aim of this study is to optimize the lipid accumulation in microalgae
by using two agricultural residues of pineapple peels and sugarcane bagasse as lowcost
organic carbon sources. Green microalgae Scenedesmus acutus was isolated and
selected for cultivation. Effects of three initial sugar concentrations and the stage for
adding sugar during cultivation on biomass and lipid production were investigated.
The results clearly showed that two-stage cultivation is more suitable than one-stage.
The maximum biomass concentration and productivity were obtained at 3.85 g/L and
160.42 mg/L/day when sugarcane bagasse was used. The highest lipid content and
lipid yield was reached at 28.05 % and 0.93 g/L when pineapple peels were used,
while in the case of sugarcane bagasse, 40.89 % and 1.24 g/L lipid content and
yield were obtained. Lipid content was found in normal condition (autotrophic) at
17.71 % which was approximately 2.13-fold lower than when sugarcane bagasse was
used (40.89 %). Biodiesel production via in situ transesterification was also investigated;
the main fatty acids of palmitic acid and oleic acid were found. This work
indicates that using agricultural residues as organic carbon sources could be able to
increase lipid content and reduce the cost of biofuel production. |
