Abstract: The invention relates to a method for recycling at least one mixed PET plastic article, the method comprising degrading at least PET of the mixed PET plastic article to monomers and/or oligomers using an enzyme and recovering the resulting monomers and/or oligomers. The method of the invention may be used for depolymerizing, simultaneously or sequentially at least two different polymers of the mixed PET plastic article, and/or for recycling at least two mixed PET plastic articles.
Abstract: The present invention relates to novel esterase, more particularly to esterase variants having improved activity compared to the esterase of SECS ID NO: 1 and the uses thereof for degrading polyester containing material, such as plastic products. The esterases of the invention are particularly suited to degrade polyethylene terephthalate, and material containing polyethylene terephthalate.

Abstract: The present invention relates to a polynucleotide encoding a recombinant scaffolding polypeptide comprising at least a signal peptide, a Cellulose Binding Domain, two cohesin domains and an S-layer Homology domain, wherein said isolated polynucleotide preferably comprises all or an active part of the nucleotide sequence as set forth in SEQ ID NO:2. The present invention further relates to vectors comprising such polynucleotides, recombinant lactic acid bacteria, and method for degrading a cellulosic biomass using such recombinant lactic acid bacteria.
Abstract: The invention concerns a microorganism which is genetically modified so as to i) synthesize an organic monomer by fermentation of a carbon source, and ii) depolymerize a polymer constituted at least by an organic monomer which it is capable of synthesizing. The invention also concerns a method for producing an organic monomer using a genetically modified microorganism of this type, as well as the coculture of this microorganism with another microorganism which is capable of synthesizing a polymer of interest.
