Biodiesel Production by the Green Microalga Scenedesmus Obliquus in a Recirculatory Aquaculture System
Applied and Environmental Microbiology, 2012Co-Authors: Shovon Mandal, Nirupama MallickAbstract:Biodiesel production was examined with Scenedesmus Obliquus in a recirculatory aquaculture system with fish pond discharge and poultry litter to couple with waste treatment. Lipid productivity of 14,400 liter ha−1 year−1 was projected with 11 cultivation cycles per year. The fuel properties of the biodiesel produced adhered to Indian and international standards.

waste utilization and biodiesel production by the green microalga Scenedesmus Obliquus
Applied and Environmental Microbiology, 2011Co-Authors: Shovon Mandal, Nirupama MallickAbstract:Scenedesmus Obliquus was cultivated in three types of waste discharges to couple waste treatment with biodiesel production. The lipid pool accumulation was boosted to 1.0 g liter−1 against 0.1 g liter−1 for the control. The waste-grown S. Obliquus showed an increase in the content of the saturated fatty acid pool, which is desirable for good-quality biodiesel.

optimization of microwave assisted lipid extraction from microalga Scenedesmus Obliquus grown on municipal wastewater
Journal of Cleaner Production, 2019Co-Authors: Xu Zhou, Wenbiao Jin, Chuan Chen, Song-fang Han, Qiongjie Guo, Qing Wang, Wentao Liu, Paul Jensen, Qilin WangAbstract:Efficient cost effective lipid extraction from microalgae is a challenging topic for large scale production of microalgae-based biodiesel. In this study, a microwave-assisted lipid extraction process was applied to the oil-rich green microalga Scenedesmus Obliquus grown on municipal wastewater. N-hexane/isopropanol solvent was used as alternative solvent. Optimal extraction parameters were determined as: operational temperature of 130 °C, extraction time of 0.25 h, solvent ratio of N-hexane/isopropanol of 3:2 (V:V), phase ratio of co-solvent/biomass was 50:1 (mL:g). Relative extraction rates of lipid and fatty acid methyl esters (FAMEs) achieved using microwave-assisted extraction (MAE) were 88.25% and 95.58%, respectively, which is higher than traditional water bath heating extraction process (WHE). In addition, compared with WHE, the apparent first order rate constant of MAE was enhanced by 18 times compared to traditional methods. Analysis using scanning electron microscopy indicated that disruption of the cell wall of Scenedesmus Obliquus by microwave led to the enhancement of solvents’ penetration and lipid extraction.

Nitrogen ion beam implantation for enhanced lipid accumulation of Scenedesmus Obliquus in municipal wastewater
Biomass and Bioenergy, 2020Co-Authors: Wenbiao Jin, Xu Zhou, Mu Wang, Chuan Chen, Song-fang HanAbstract:Abstract Breeding of high-lipid content microalgae in municipal wastewater is critical for large-scale microalgal biodiesel production. In this study, a strain of biodiesel promising microalga Scenedesmus Obliquus with good stain resistance was obtained by N+ ion implantation, which was named as S1-A3. In the selenite enrichment (SE) medium, the lipid content of S1-A3 was up to 46.92%, which was increased by 24.1% than the original strain. Meanwhile, after 7 days of cultivation, the removal rates of TP,TN, NH4+-N and COD in wastewater attained 95.72%, 80.30%, 87.25% and 85.43% by S1-A3, respectively. S1-A3 had a good genetic stability in both municipal wastewater and SE medium, and its lipid production capacity was improved after four successive cultivation in wastewater. RAPD analysis showed that the mutant and the original strain were interspecific variations. Therefore, N+ ion implantation was proved to be an approach that can significantly improve the lipid content and adaptability of Scenedesmus Obliquus.
