Abstract Ratios of glycerol dialkyl tetraethers (GDGT), which are membrane lipids bacteria and archaea, at the base several paleoenvironmental proxies. They frequently applied to soils as well lake‐ marine sediments generate records past temperature soil pH. To derive meaningful environmental information from these reconstructions, high analytical reproducibility is required. Based on submitted results by 39 laboratories across world, employ a diverse range quantification methods, we...
Abstract Sterols and hopanoids are chemically structurally related lipids mostly found in eukaryotic bacterial cell membranes. Few species have been reported to produce sterols this anomaly had originally ascribed lateral gene transfer (LGT) from eukaryotes. In addition, the functions of these bacteria unknown functional overlap between is still unclear. Gemmata obscuriglobus a bacterium Planctomycetes phylum that synthesizes sterols, contrast its hopanoid-producing relatives. Here we show...
