Microorganisms able to grow on low molecular weight aliphatic hydrocarbon gases, i.e. the n-alkanes, ethane, propane and butane, and the terminal alkenes, ethylene, propylene and butylene, are not uncommon but mainly belong to certain taxonomic groups. These microbes are described in this review together with the pathways by which the hydrocarbons are assimilated. Microbial oxidation of the volatile alkadiene, isoprene, is also discussed. Avenues for possible commercial exploitation of these metabolic activities are also reviewed. Short-chain n-alkane-utilising organisms have been investigated as tools in petroleum exploration and for production of single cell protein. More recently microbes grown on gaseous hydrocarbons other than methane have been evaluated for use in biotechnological production of epoxides, synthesis of chiral epoxyalkanes and as catalysts in bioremediation systems.  2005 Society of Chemical IndustryThe supplementary material for this paper is now available at http://www.interscience.wiley.com/jpages/ 0268-2575/suppmat/

Living cells of Mycobacterium sp. NRRL B-3683 were immobilized by adsorption on different types of solid carriers in order to produce androsta-1,4-diene-3,17-dione (ADD) from cholesterol. Activated alumina proved to be the most preferred carrier for long-term operation when glucose and peptone were added to the reaction medium. In a repeated-batch process, the maximum productivity of ADD was about 0.19 g/l per day with a molar conversion rate of 77% when 1.0 g/l of cholesterol was added to the reaction medium. The half-life of the immobilized cells was more than 45 days and the system could be reactivated by incubating the immobilized cells in a cell growth medium.

Immobilization of gas-utilizing microorganism strains (Mycobacteria, Rhodococcus, methane-utilizers) on inorganic supports based on alumina, silicates, and carbon was carried out to develop heterogeneous biocatalysts for the biotechnologic processes, including the process of propene epoxidation. Adsorption ability of these microorganisms, biocatalytic properties of resting and immobilized bacterial cells, and effect of immobilization techniques on biocatalysis were studied. An approach of double immobilization using inorganic materials (supports and gel) was proposed as simple, universal, and available method to immobilize bacterial cells, resulting in a higher retention (up to 100%) of cells' enzymatic activity and enhanced stability.
