Microbial Surface Colonization and Biofilm Development in Marine Environments

TL;DR: Recent progress in the study of marine microbial surface colonization and biofilm development is synthesized and discussed and questions are posed for targeted investigation of surface-specific community-level microbial features to advance understanding ofsurface-associated microbial community ecology and the biogeochemical functions of these communities.
Journal ArticleDOI

Occurrence and abundance of 6-methyl branched glycerol dialkyl glycerol tetraethers in soils : Implications for palaeoclimate reconstruction

TL;DR: In this article, the authors quantified the fractional abundance of 6-methyl brGDGTs in globally distributed soils and showed that they are abundant components, comprising on average 24% of the total amount of brDGTs.
Journal ArticleDOI

The effect of improved chromatography on GDGT-based palaeoproxies

TL;DR: In this article, the authors presented a method based on two ultra-high performance liquid chromatography silica columns capable of separating a wide range of GDGTs with good resolution and which compares favorably with previously published methods.

Characterisation of membrane phospholipids and glycolipids from a halophilic archaebacterium by high‐performance liquid chromatography/electrospray mass spectrometry

TL;DR: Combined high-performance liquid chromatography and electrospray mass spectrometry (LC/ES-MS) has been used for direct characterisation of the polar membrane lipids in total lipid extracts from Halobacterium salinarium, a species of halophilic archaebacterium, providing a further example of the previously recognised existence of isoprenologues of diphytanyl archaeols which occur as minor components of Archaebacterial membrane lipIDS.

Preservation of microbial lipids in geothermal sinters.

TL;DR: Investigation of lipid preservation in active and inactive geothermal silica sinters from Champagne Pool, Waiotapu, New Zealand reveals a wide range of bacterial biomarkers, including free and bound fatty acids, 1,2-di-O-alkylglycerols (diethers), and various hopanoids, and indicates that incorporated lipids can be well preserved.

Reconstruction of the Archaeal Isoprenoid Ether Lipid Biosynthesis Pathway in Escherichia coli Through Digeranylgeranylglyceryl Phosphate

TL;DR: This investigation established roles for four A. fulgidus genes in the isoprenoid ether lipid pathway for D GGGP biosynthesis and provides a platform useful for identification of subsequent, currently unknown, steps in tetraether lipid biosynthesis proceeding from DGGGP, which is the presumed substrate for the head-to-head coupling reaction yielding unsaturated caldarchaeol.
