Leaf Waxes and Hemicelluloses in Topsoils Reflect the δ2H and δ18O Isotopic Composition of Precipitation in Mongolia

open access: yesFrontiers in Earth Science, 2020
Compound-specific hydrogen and oxygen isotope analyzes on leaf wax-derived n-alkanes (δ2Hn–alkane) and the hemicellulose-derived sugar arabinose (δ18Oara) are valuable, innovative tools for paleohydrological reconstructions.

Review of Classification of PCMs, with a Focus on the Search for New, Suitable PCM Candidates

open access: yesEnergies
With a growing number of PCMs and new, suitable PCM candidates, an overview is not only important, but also increasingly complex. Classification of PCM was thus changed significantly in the past decades.

Nanorheology of liquid alkanes [PDF]

open access: yesFluid Phase Equilibria, 1998
Abstract We report molecular dynamics simulations of liquid alkanes, squalane and tetracosane, confined between moving walls to which butane chains are tethered, effectively screening the details of the wall. As in an experiment, heat is removed by thermostatting the tethered molecules.

The genome of the moderate halophile Amycolicicoccus subflavus DQS3-9A1(T) reveals four alkane hydroxylation systems and provides some clues on the genetic basis for its adaptation to a petroleum environment. [PDF]

open access: yesPLoS ONE, 2013
The moderate halophile Amycolicicoccus subflavus DQS3-9A1(T) is the type strain of a novel species in the recently described novel genus Amycolicicoccus, which was isolated from oil mud precipitated from oil produced water.

Anaerobic alkane biodegradation by cultures enriched from oil sands tailings ponds involves multiple species capable of fumarate addition.

open access: yesFEMS Microbiology Ecology, 2015
A methanogenic short-chain alkane-degrading culture (SCADC) was enriched from oil sands tailings and transferred several times with a mixture of C6, C7, C8 and C10 n-alkanes as the predominant organic carbon source, plus 2-methylpentane, 3-methylpentane ...

Diverse alkane hydroxylase genes in microorganisms and environments

open access: yesScientific Reports, 2014
AlkB and CYP153 are important alkane hydroxylases responsible for aerobic alkane degradation in bioremediation of oil-polluted environments and microbial enhanced oil recovery.

Metabolic and stress responses of Acinetobacter oleivorans DR1 during long‐chain alkane degradation

open access: yesMicrobial Biotechnology, 2017
Summary Acinetobacter oleivorans DR1 can utilize C12–C30 alkanes as a sole carbon source but not short‐chain alkanes (C6, C10). Two copies of each alkB‐, almA‐ and ladA‐type alkane hydroxylase (AH) are present in the genome of DR1 cells.

Functional screening of aldehyde decarbonylases for long-chain alkane production by Saccharomyces cerevisiae

open access: yesMicrobial Cell Factories, 2017
Background Low catalytic activities of pathway enzymes are often a limitation when using microbial based chemical production. Recent studies indicated that the enzyme activity of aldehyde decarbonylase (AD) is a critical bottleneck for alkane ...

In situ detection of anaerobic alkane metabolites in subsurface environments

open access: yesFrontiers in Microbiology, 2013
Alkanes comprise a substantial fraction of crude oil and refined fuels. As such, they are prevalent within deep subsurface fossil fuel deposits and in shallow subsurface environments such as aquifers that are contaminated with hydrocarbons.
