Environmental Effects on Cell Composition

Hu, Qiang·2013·Handbook of Microalgal Culture

Abstract

Many microalgae, regardless of their origins, possess a similar biochemical composition (on a basis of total organic carbon in the cells), particularly the relative amounts of crude protein, lipid, and carbohydrate, when grown rapidly under favorable culture conditions. This default setting, however, can be readily changed by environmental factors to bestow maximum flexibility and robustness on microalgae to permit proliferation or survival in the changing environment. In this chapter, the effects of major environmental factors (light, temperature, nitrogen, phosphorus, iron, salinity, pH, etc.) on the biochemical composition of microalgae are described and the biotechnological implications are discussed.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Variations in pH and salinity introduce osmotic and ionic stresses that influence cell wall composition and synthesis of compatible solutes, leading to modifications in carbon-rich biomolecules and impacting the structural properties and reactivity of derived carbon materials.

    “Additionally, variations in pH and salinity introduce osmotic and ionic stresses that influence cell wall composition and the synthesis of compatible solutes.Such environmental stresses lead to modifications in the types and arrangements of carbon-rich biomolecules within the cells, ultimately impacting the structural properties and reactivity of the derived carbon materials.”
  • Environmental conditions such as light intensity, temperature, nutrient availability, pH, and salinity influence the biochemical composition of algae, thereby affecting the characteristics of carbon materials derived from them.

    “Environmental conditions exert a significant influence on the biochemical composition of algae, thereby affecting the characteristics of the carbon materials derived from them.”

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.
