Phytosterols from Dunaliella tertiolecta and Dunaliella salina: a potentially novel industrial application

Francavilla, Matteo, Trotta, Pasquale, Luque, Rafael·2010·Bioresource Technology

Abstract

Sterols have been extracted and analysed from Dunaliellatertiolecta and Dunaliella salina, in order to evaluate a potentially novel industrial exploitation of these microalgae as source of phytosterols. The effect of salt concentration on sterols yields has been studied varying the quantities of NaCl into culture medium. Twelve sterols were identified by Gas-chromatographic MS/MS analysis for both algal strains. The most abundant phytosterols were (22E,24R)-methylcholesta-5,7,22-trien-3beta-ol (ergosterol) and (22E,24R)-ethylcholesta-5,7,22-trien-3beta-ol (7-dehydroporiferasterol). The whole sterol fraction consisted mainly of phytosterols (C(28) and C(29) sterols). Good yields of total sterols were achieved at lower salt concentration (1.3% and 0.89% of dry weight in D. tertiolecta and D. salina, respectively, at 0.6M NaCl), while an increase in salt concentration resulted in a significant decrease in total sterols yield.

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

  • D. tertiolecta and D. salina grown under different salt concentrations produce abundant phytosterols such as ergosterol and 7-dehydroporiferasterol.

    “Francavilla et al. (2010) reported that D. tertiolecta and D. salina grown under different salt concentrations produced abundant phytosterols such as (22E, 24R)-methylcholesta-5,7,22-trien-3b-ol (ergosterol) and (22E, 24R)-ethylcholesta-5,7,22-trien-3b-ol (7-dehydroporiferasterol).”

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.
