Bacterium Produces “Organic Dishwashing Liquid” to Degrade Oil Bacterium Produces “Organic Dishwashing Liquid” to Degrade Oil

A study led by the University of Bonn has illuminated the mechanism by which this marine creature produces the detergent


The marine bacterium Alcanivorax borkumensis feeds on oil, multiplying rapidly in the wake of oil spills, and thereby accelerating the elimination of the pollution, in many cases. It does this by producing an “organic dishwashing liquid” which it uses to attach itself to oil droplets. Researchers from the University of Bonn, RWTH Aachen University, Heinrich Heine University Düsseldorf and research center Forschungszentrum Jülich have now discovered the mechanism by which this “organic dishwashing liquid” is synthesized. Published in the prominent international journal Nature Chemical Biology, the research findings could allow the breeding of more efficient strains of oil-degrading bacteria.

The red-marked bacteria with the gene cluster switched off - were no longer able to synthesize the detergent. The bacteria were then unable to attach to the surface of oil droplets (left) the way they usually do (right).

Loosely translated into English, the Latin name of the bacterium is “alkane eaters from Borkum.” Indeed, the name says it all, for alkanes are chains of hydrocarbons that exist in petroleum in large quantities. A. borkumensis feeds on energy-rich chains which occur naturally in the sea—and on non-naturally-occurring chains like those dispersed in oil spills. In many cases the bacteria multiply rapidly, thereby accelerating the pollution-clearing process.

Participating institutions and funding: The University of Bonn, RWTH Aachen University, the Heinrich Heine University Düsseldorf and Forschungszentrum Jülich were involved in the research study, which was funded by the German Research Foundation (DFG) and the Federal Ministry of Education and Research (BMBF).
