Abstract

Microalgae are a kind of promising raw material for bioenergy production and carbon sequestration. To enhance cell growth and production efficiency, great efforts were made for exploring the appropriate intensity and quality of light to improve the synthesis of the value-added products. The aggregation-induced emission (AIE) material (Astrazon Brilliant Red 4G), active for converting blue-green light to red light (630–680 nm), was for the first time applied in the research to achieve high fatty acid yield with considerable carbon–neutral ability. After 10 days-incubation, it revealed that AIE light-converting films boosted the biomass of microalgae Scenedesmus obliquus, Phaeodactylum tricornutum, and Chlamydomonas reinhardtii by 13.00 %, 28.00 %, and 26.00 %, and the total lipid contents increased by 34.60 %, 17.74 %, and 22.63 %, with the carbon sequestration capacity raised by 17.18 %, 38.89 %, and 35.71 %. Furthermore, AIE light-converting films promoted the accumulation of unsaturated fatty acids (UFAs) in all three microalgae. Our study demonstrated the potential application of AIE light-converting films for cultivating microalgae to capture high carbon dioxide for photosynthesize carbon–neutral energy and high-valued active compounds.

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.
