Abstract(s) :

(Anglais) Most plastics are released to the environment in landfills and end up in the sea, inducing large ecological and health impacts. Nevertheless, plastics could constitute a physical substrate and potential carbon source for microorganisms. Bacterial consortia, sampled from marine plastisphere (Mediterranean, Corsica), were grown with a piece of plastic film as the main carbon source in an attempt to select potential candidates for the plastic degradation. After the selection and isolation of Alcanivorax borkumensis, its capacity to form biofilm and degrade plastics was monitored. Results demonstrate clearly that A. borkumensis forms large biofilms on the plastic surface and was also able to degrade LDPE.
