Regulation of Photosynthetic Pigments in Micro-algae by Multiple Environmental Factors: A Dynamic Balance Hypothesis
Abstract
summary Environmental effects on the concentration of photosynthetic pigments in micro‐algae can be explained by dynamics of photosystem synthesis and deactivation. A model that couples photosystem losses to the relative cellular rates of energy harvesting (light absorption) and assimilation predicts optimal concentrations of light‐harvesting pigments and balanced energy flow under environmental conditions that affect light availability and metabolic rates. Effects of light intensity, nutrient supply and temperature on growth rate and pigment levels were similar to general patterns observed across diverse micro‐algal taxa. Results imply that dynamic behaviour associated with photophysical stress, and independent of gene regulation, might constitute one mechanism for photo‐acclimation of photosynthesis.

Modifying photosynthetic pigments, altering photosynthesis-related proteins, and improving activity and stability of carbon fixation enzymes can help algae maintain efficient carbon capture under diverse cultivation conditions.
“For instance, modifying photosynthetic pigments [278], altering photosynthesis-related proteins [279], and improving the activity and stability of carbon fixation enzymes [280] can help algae maintain efficient carbon capture under diverse cultivation conditions.”

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.
