![]() ![]() We report here the purification and characterization of an enzyme from the wax ester-accumulating bacterium Marinobacter aquaeolei VT 8, which is a proposed fatty aldehyde reductase in this pathway. An essential step in the pathway is the reduction of a fatty aldehyde to the corresponding fatty alcohol, although the enzyme responsible for catalyzing this reaction has yet to be identified in bacteria. The synthesis of wax esters from fatty acids is proposed to require the action of a four-enzyme pathway. Wax esters, ester-linked fatty acids and long-chain alcohols, are important energy storage compounds in select bacteria. Purification, Characterization, and Potential Bacterial Wax Production Role of an NADPH-Dependent Fatty Aldehyde Reductase from Marinobacter aquaeolei VT 8▿ †aquaeolei and help to more completely define the biogeochemical niche of the genus. ![]() The versatility and interrelatedness of these metabolic potentials coin the opportunistic character of M. Fitting with these observations, genome annotation has revealed: four variations of the TCA cycle, complete pathways of glycolysis and the degradation of more complex hydrocarbons (including octane oxidation and cyclohexanol degradation), alternative phosphorous and nitrogen sources, genes for the use of nitrate and sulfate as electron acceptors as well as complete pathways for sulfite oxidation, denitrification and iron oxidation. aquaeolei was known to be a facultative anaerobe with the ability to utilize various carbon sources. Isolated from an oil well in Southern Vietnam, M. This study has determined the genomic potential of one particular strain - Marinobacter aquaeolei VT 8, which relies on a very large set of survival strategies. ![]() They are known to degrade hydrocarbons and show some extremophilic lifestyles, such as pyschrophily, oligotrophy and halotolerance. Members of this genus are found throughout the water column, in the deep sea, and are often associated with hydrothermal plume particles and marine snow. The family of Marinobacter is one of the most ubiquitous in the ocean. The genomic potential of Marinobacter aquaeolei - A biogeochemical opportunotroph ![]()
