Anaerobic Oxidation of Ethane, Propane, and Butane by Marine Microbes: A Mini Review

The deep ocean and its sediments are a continuous source of non-methane short-chain alkanes (SCAs) including ethane, propane, and butane. Their high global warming potential, and contribution to local carbon and sulfur budgets has drawn significant scientific attention. Importantly, microbes can use gaseous alkanes and oxidize them to CO2, thus acting as effective biofilters. A relative decreas...

Propane and n-butane oxidation by Pseudomonas putida GPo1.

Propane and n-butane inhibit methyl tertiary butyl ether oxidation by n-alkane-grown Pseudomonas putida GPo1. Here we demonstrate that these gases are oxidized by this strain and support cell growth. Both gases induced alkane hydroxylase activity and appear to be oxidized by the same enzyme system used for the oxidation of n-octane.

Carbon and hydrogen isotope fractionation associated with the aerobic microbial oxidation of methane, ethane, propane and butane

Carbon isotope fractionation factors associated with the aerobic consumption of methane (C1), ethane (C2), propane (C3), and nbutane (C4) were determined from incubations of marine sediment collected from the Coal Oil Point hydrocarbon seep field, located offshore Santa Barbara, CA. Hydrogen isotope fractionation factors for C1, C2 and C3 were determined concurrently. Fresh sediment samples fro...

NON-RESONANT THIRD-ORDER SUSCEPTIBILITIES MEASURED FOR ETHANE, PROPANE AND n-BUTANE

Third-order non-linear susceptibilities have been measured for ethane, propane and n-butane at three wavelengths in the visible region by means of gas-phase electric-field-induced second-harmonic generation (ESHG). The susceptibilities are found to be large and strongly frequency dependent. The possible application of these results to the calibration of the non-resonant background in coherent a...

Biological formation of ethane and propane in the deep marine subsurface.

Concentrations and isotopic compositions of ethane and propane in cold, deeply buried sediments from the southeastern Pacific are best explained by microbial production of these gases in situ. Reduction of acetate to ethane provides one feasible mechanism. Propane is enriched in (13)C relative to ethane. The amount is consistent with derivation of the third C from inorganic carbon dissolved in ...
