Scenedesmus obliquus CNW-N as a potential candidate for CO2 mitigation and biodiesel production

Ho, Shih-Hsin, Chen, Wen-Ming, Chang, Jo-Shu·2010·Bioresource Technology

Abstract

This study aimed to achieve higher CO(2) consumption ability and lipid productivity of an indigenous microalgal isolate Scenedesmus obliquus CNW-N by a two-stage cultivation strategy. The microalga strain was first cultivated with 10% CO(2) using a nutrient-rich medium to promote cell growth, which was followed by a nutrient-deficient condition to trigger lipid accumulation. The optimal biomass productivity, lipid productivity, and CO(2) consumption rate were 292.50mgL(-1)d(-1), 78.73mgL(-1)d(-1) (38.9% lipid content per dry weight of biomass), and 549.90mgL(-1)d(-1), respectively. This performance is superior to the results from most of the related studies. Under the nutrient-deficient condition, the microalgal lipid was mainly composed of C16/C18 fatty acids (accounting for 89% of total fatty acids), which is suitable for biodiesel synthesis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
