Scenedesmus obliquus metabolomics: effect of photoperiods and cell growth phases
Abstract
Environmental factors directly affect the growth and composition of microalgal biomass. Therefore, the present work analyzed the metabolomics (amino acids, organic acids, and fatty acids) of the microalga Scenedesmus obliquus cultivated in 24:0 and 12:12 (light:dark) photoperiods and different phases of cell growth. Furthermore, the metabolites were related to protein, lipid, and chlorophyll contents at the end of cultivation. The highest biomass concentration (4020 mg L- 1) and protein (47.3%) were obtained in culture under constant illumination. The cultivation 12:12 (light:dark) photoperiod triggered higher production of lipids (23.0%) and chlorophylls (26.4 mg g- 1) by S. obliquus. Microalgal metabolites were greatly affected by photoperiod and by phase of cell growth. Thus, metabolite production could be related to both the environmental conditions under which cultivation occurred and to the different concentrations of products (proteins, lipids, and chlorophylls) present in the S. obliquus biomass.

Scenedesmus obliquus grown under a 12:12 light/dark photoperiod had 20% more total chlorophylls (26.4 mg/g) compared to continuous lighting.
“Vendruscolo et al. (2019) demonstrated that Scenedesmus obliquus grown under a 12:12 light/dark photoperiod had 34% higher lipid content (23.0%) and 20% more total chlorophylls (26.4 mg/g) compared to continuous lighting, although continuous light favored protein accumulation (47.3%).”

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.
