Biocapture of CO 2 from biogas by oleaginous microalgae for improving methane content and simultaneously producing lipid

Abstract

This study aimed to use oleaginous microalgae to capture CO2 from biogas for improving methane content and simultaneously producing lipid. Several microalgae were screened for their ability to grow and produce lipid using CO2 in biogas. A marine Chlorella sp. was the most suitable strain for capturing CO2 and producing lipid using biogas (50% v/v CO2 in methane) as well as using 50% v/v CO2 in air. The medium and operating conditions were optimized through response surface methodology (RSM). The optimal concentrations of KNO3 and K2HPO4 were 0.80gL(-1) and 0.06gL(-1), respectively. The optimal operating conditions were: initial pH of 7.8, initial cell concentration of 10(7.5)cellsmL(-1), light intensity of 4500lux and gas flow rate of 0.03Lmin(-1). After optimization, 89.3% of CO2 was removed from biogas and the methane content was increased up to 94.7%. The lipid productivity was 94.7mgL(-1)day(-1).

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.
