Application of Fourier transform infrared (FT-IR) spectroscopy in determination of microalgal compositions

Meng, Yingying, Yao, Changhong, Xue, Song, Yang, Haibo·2014·Bioresource Technology

Abstract

Fourier transform infrared spectroscopy (FT-IR) was applied in algal strain screening and monitoring cell composition dynamics in a marine microalga Isochrysis zhangjiangensis during algal cultivation. The content of lipid, carbohydrate and protein of samples determined by traditional methods had validated the accuracy of FT-IR method. For algal screening, the band absorption ratios of lipid/amide I and carbo/amide I from FT-IR measurements allowed for the selection of Isochrysis sp. and Tetraselmis subcordiformis as the most potential lipid and carbohydrate producers, respectively. The cell composition dynamics of I. zhangjiangensis measured by FT-IR revealed the diversion of carbon allocation from protein to carbohydrate and neutral lipid when nitrogen-replete cells were subjected to nitrogen limitation. The carbo/amide I band absorption ratio had also been demonstrated to depict physiological status under nutrient stress in T. subcordiformis. FT-IR serves as a tool for the simultaneous measurement of lipid, carbohydrate, and protein content in cell.

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?

  • Off-line FTIR determination of the carbohydrate/amide I ratio can predict photosynthetic efficiency with high accuracy (R2 = 0.998).

    “Alternatively, the ratio of carbohydrate/amide I determined by off-line FTIR can be used to predict photosynthetic efficiency with high accuracy (R 2 = 0.998) [27]”
  • FTIR has been used to measure or infer critical process parameters (CPPs) and critical quality attributes (CQAs) commonly monitored in microalgae reactions, apart from measuring intracellular components.

    “Furthermore, apart from measuring intracellular components of microalgae, FTIR has been used to measure or infer a number of critical process parameters (CPPs) and critical quality attributes (CQAs) that are commonly monitored in microalgae reactions.”
  • FTIR spectroscopy has been used for rapid assessment of lipids without lipid extraction and to monitor changes within intracellular macromolecular pools of microalgae.

    “Many of the studies have reported the use of FTIR spectroscopy in the rapid assessment of lipids, without the need for lipid extraction and to monitor the changes within the intracellular macromolecular pools of microalgae [15,20 -23].”

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.
