Fatty acid biomarkers to verify cyanobacteria feeding abilities of herbivorous consumers
Open accessAbstract
To search useful fatty acid biomarkers for cyanobacteria feeding abilities of control organisms, we compared fatty acid composition of six cultured algal species in four taxonomic groups (Cryptophyceae, Bacillariophyceae, Chlorophyceae, and Cyanophyceae) and evaluated several fatty acid biomarkers using data from three lakes that varied in trophic status. In addition, a laboratory feeding experiment was conducted to verify fatty acid markers for cyanobacteria using Selenastrum capricornutum (Chlorophyceae) and Microcystis aeruginosa (Cyanophyceae). Two strains of M. aeruginosa had the highest content of 18:3ω6 while Anabaena sp. had a relatively high content of 18:1ω7 among the six species. Both 18:1ω7 and 18:3ω6 (γ-linolenic acid, GLA) concentrations showed significant linear relationships with cyanobacteria biomass in natural systems. In the laboratory feeding experiment, a principal component analysis score plot indicate that fatty acid composition of Branchinella kugenumaensis fed with M. aeruginosa became similar to that of the cyanobacterial population. In S-plot of partial least square discriminant analysis, 18:3ω6 and 18:1ω7 were selected for fairy shrimps feeding on M. aeruginosa, whereas 18:3ω3 (ALA, α-linolenic acid) and 18:1ω9 were selected for those feeding on S. capricornutum. 18:3ω6 content of B. kugenumaensis fed with M. aeruginosa significantly increased after the third day and 18:1ω7 content was significantly different from the other feeding group after six days. In particular, 18:3ω6 appeared to be a useful fatty acid biomarker for M. aeruginosa in tracing trophic relations of herbivorous organisms in freshwater ecosystems.

Many marine cyanobacteria contain considerable amounts of GLA in the form of glycolipids.
“Many marine cyanobacteria contain considerable amounts of GLA in the form of glycolipids [9,10,11].”

The 'Fatty acid profiles of cultured phytoplankton' section reports high GLA content in two strains of Microcystis aeruginosa. It does not establish that many marine cyanobacteria contain considerable GLA, or that their GLA is in glycolipids. (LLM, conf=0.87)

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.
