Archaeal lipostratigraphy of the Scotian Slope shallow sediments, Atlantic Canada [PDF]

Biogeosciences
The Scotian Slope in the North Atlantic Ocean extends for ∼ 500 km along the coast of Nova Scotia, Canada. Its surface sediments host microbial communities, which respond to complex geochemical drivers that not only include communication with the ...

Structure–function relationships in pure archaeal bipolar tetraether lipids

Chemical Science, 2023
A series of archaeal bipolar glycerol dialkyl glycerol tetraether (GDGT) lipids were synthesized. Structural properties of self-assembled structures of GDGTs were studied and related to functional behavior such as membrane fusion.

Exploring robustness of hybrid membranes under high hydrostatic pressure and temperature

Frontiers in Microbiology
Bacterial membranes are typically composed of ester-bonded fatty acid (FA), while archaeal membranes consist of ether-bonded isoprenoids, differentiation referred to as the ‘lipid divide’.

Biocatalytic Ether Lipid Synthesis by an Archaeal Glycerolprenylase

Angewandte Chemie International Edition
AbstractAlthough ethers are common in secondary natural products, they are an underrepresented functional group in primary metabolism. As such, there are comparably few enzymes capable of constructing ether bonds in a general fashion. However, such enzymes are highly sought after for synthetic applications as they typically operate with higher ...

Membrane homeoviscous adaptation in the piezo-hyperthermophilic archaeon Thermococcus barophilus

Frontiers in Microbiology, 2015
The archaeon Thermococcus barophilus, one of the most extreme members of hyperthermophilic piezophiles known thus far, is able to grow at temperatures up to 103°C and pressures up to 80MPa. We analyzed the membrane lipids of T. barophilus by HPLC-MS as a

Structural elucidation and environmental distributions of butanetriol and pentanetriol dialkyl glycerol tetraethers (BDGTs and PDGTs) [PDF]

Biogeosciences, 2020
Butanetriol and pentanetriol dialkyl glycerol tetraethers (BDGTs and PDGTs) are membrane lipids, recently discovered in sedimentary environments and in the methanogenic archaeon Methanomassiliicoccus luminyensis.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...
