Plastics present to modern society remarkable performance characteristics desired by a wide range of consumers but their fate in the marine environment has become a massive management problem. We will apply a combination of state of the art spectroscopic techniques including Resonance Raman, Time-resolved FTIR, Fluorescence and time-resolved Laser induced breakdown spectroscopy to probe the Biodegradation of (bio)-plastics by a variety of marine microorganisms. Emphasis will be given in the interactions of the genus Thalassococcus which belongs to the family Rhodobacteracease and capable to degrade carbazole. Sagittula stellata will also be used which is a heterotrophic member of the alpha proteobacteria Roseobacter clade typically found in marine environments responsible for the degradation of cellulose, lignin related compounds and for the oxidation of dimethylsul sulfide (DMS) to dimethyl sulfoxide (DMSO) that is coupled to ATP synthesis and other organic sulfur compounds typically found in surface will be also used in the biodegradation of bioplastics.
