TLDR
Branched-chain fatty acids of the iso and anteiso series occur in many bacteria as the major acyl constituents of membrane lipids and are an important criterion used to aid identification and classification of bacteria.About:

Towards multiproxy, ultra-high resolution molecular stratigraphy: Enabling laser-induced mass spectrometry imaging of diverse molecular biomarkers in sediments
Lars Wörmer,Jenny Wendt,Susanne Alfken,Jinxiang Wang,Marcus Elvert,Verena B Heuer,Kai-Uwe Hinrichs +6 more
TL;DR: In this paper, mass spectrometry imaging (MSI) is used for the detection of organic molecules within sediment matrix. But, ionization of organic compounds within their sediment matrix remains a critical challenge, as most compounds relevant to molecular stratigraphy are not properly ionized in the presence of conventional matrices, but require atypical ones such as those based on carbon or silver.

Transhydrogenase and Growth Substrate Influence Lipid Hydrogen Isotope Ratios in Desulfovibrio alaskensis G20
TL;DR: Fractionation correlated with growth rate, a pattern that has also been observed in the fractionation of sulfur isotopes during dissimilatory sulfate reduction by sulfate-reducing bacteria.
Journal ArticleDOI
Fracture zone-scale variation of trace elements and stable isotopes in calcite in a crystalline rock setting
TL;DR: In this article, the isotopic and chemical heterogeneity of calcites in water-conducting fracture zones with different crystalline wall rock compositions at different scales was investigated with the aim of increasing the understanding about the isotope and chemical variability of calcite.

Lipidomics of the sea sponge Amphimedon queenslandica and implication for biomarker geochemistry

TL;DR: The results provide additional support for the poriferan affinity of 24‐isopropylcholestanes in Neoproterozoic‐age rocks (the “sponge biomarker” hypothesis) and suggest that some algal proxies in the geochemical record could also have animal contributions.

Effects of partial replacement of maize in the diet with crude glycerin and/or soyabean oil on ruminal fermentation and microbial population in Nellore steers
Yury Tatiana Granja-Salcedo,Juliana Duarte Messana,Vinícius Carneiro de Souza,Ana Veronica Lino Dias,Luciano Takeshi Kishi,Lucas Rocha Rebelo,Telma Teresinha Berchielli +6 more
TL;DR: CG associated with lipids could be an energy source, which is a useful strategy for the partial replacement of maize in cattle diets, could result in reduced total N excretion and ruminal methanogens without affecting intake and digestibility.

Fatty acid and polar lipid composition in the classification of Cellulomonas, Oerskovia and related taxa
TL;DR: Two-dimensional thin-layer chromatography showed that almost identical and very characteristic polar lipid patterns were given by all the organisms under study: the only major components were diphosphatidylglycerol, phosph atidylinositol and two phospho-glycolipids chromatographing similarly to, but distinguishable from, the mono- and diacyl phosphatidolinositols characteristic of Nocardia and other actinomycetes.
