Abstract
To better understand the molecular mechanisms involved in the biodegradation of hydrocarbon compounds from the "Erika" oil-spill, we have studied the ability of Marinobacter hydrocarbonoclasticus strain sp 17 to cope with hexadecane as sole carbon and energy source. Growth kinetics of cultures shifted from acetate to hexadecane revealed the presence of a 20 hours adaptation phase. Changes in global protein expression in response to hexadecane was analyzed by two-dimensional gel electrophoresis. Of the 370 proteins detected 42 had their expression level altered in presence of hexadecane indicating that alkane adaptation may involve many cellular functions.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
