Alkanes are saturated apolar hydrocarbons that range from their simplest form, methane, to high-molecular-weight compounds. Although alkanes were once considered biologically recalcitrant under anaerobic conditions, microbiological investigations have now identified several microbial taxa that can anaerobically degrade alkanes. Here we review recent discoveries in the anaerobic oxidation of alkanes with a specific focus on archaea that use specific methyl coenzyme M reductases to activate their substrates.

This sequence provides important insights into the genetic mechanisms of propane and n-butane metabolism, organic sulfide and beta-sitosterol biotransformation, glycolipid biosurfactant production, and heavy metal resistance in actinobacteria.

Enzymes of the AlkB and CYP153 families catalyze the first step in the catabolism of medium-chain-length alkanes, selective oxidation of the alkane to the 1-alkanol, and enable their host organisms to utilize alkanes as carbon sources. Small, gaseous alkanes, however, are converted to alkanols by evolutionarily unrelated methane monooxygenases. Propane and butane can be oxidized by CYP enzymes engineered in the laboratory, but these produce predominantly the 2-alkanols.

Staircase electrophoresis (SCE) in polyacrilamide gels was used to analyze the stable low-molecular weight (LMW) RNA profiles of several propane and butane oxidizing bacteria belonging to different species and genera. Differences in the number and distribution of the RNA bands in these profiles allowed us to differentiate among them. Congruent results were found between the established classification of these bacteria and results obtained by LMW RNA profiling and moreover, some misclassified strains can be assigned to the correct genus and species using this technique.
