Production of alkanes from CO2 by engineered bacteria
Biotechnology for Biofuels, 2018 Background Microbial biosynthesis of alkanes is considered a promising method for the sustainable production of drop-in fuels and chemicals. Carbon dioxide would be an ideal carbon source for these production systems, but efficient production of long ...

Degradation of alkanes by bacteria [PDF]
Environmental Microbiology, 2009 SummaryPollution of soil and water environments by crude oil has been, and is still today, an important problem. Crude oil is a complex mixture of thousands of compounds. Among them, alkanes constitute the major fraction. Alkanes are saturated hydrocarbons of different sizes and structures.

Induction of alkane hydroxylase proteins by unoxidized alkane in Pseudomonas putida [PDF]
Journal of Bacteriology, 1975 In vitro complementation assays have been used to demonstrate the induction of alkane hydroxylase proteins in mutants lacking the ability to convert n-alkanes to their primary alcohols. Purified heptane is an effective inducer in a mutant lacking detectable hydroxylase activity.

Role of cysteine residues in the structure, stability, and alkane producing activity of cyanobacterial aldehyde deformylating oxygenase. [PDF]
PLoS ONE, 2015 Aldehyde deformylating oxygenase (AD) is a key enzyme for alkane biosynthesis in cyanobacteria, and it can be used as a catalyst for alkane production in vitro and in vivo.

Gibbs Films of Semi-Fluorinated Alkanes at the Surface of Alkane Solutions [PDF]
Langmuir, 2002 Adsorbed monolayer phases of semi-fluorinated alkanes F(CF 2 ) 1 2 (CH 2 ) m H with m = 12, 14, 16, and 18 (denoted F 1 2 H m ) at the free surface of their solutions in H 1 2 and H 1 6 solvents (dodecane, bicyclohexyl, and hexadecane) were studied by surface tension measurements and surface-sensitive X-ray techniques. Solutions in the two H 1 2

A theoretical study of alkane protonation in HF/SbF5 superacid system
Journal of the Brazilian Chemical Society, 2000 Ab initio calculations for the protonation of the C-H and C-C bonds of methane, ethane, propane and isobutane by a superacid moiety was carried out. For the C-H protonation (H/H exchange) the transition state resembles an H-carbonium ion coordinated with
