abstract = {The end-of-life plastic crisis is very prominent in the
research area and even in the public realm. Especially, for
plastic polymers that are difficult to recycle via
traditional routes such as the polyurethanes (PUs), novel
routes should be investigated. In 2015, PU contributed about
16 million metric tons of global plastic waste. While
polymer degradation via chemical routes such as solvolysis
and pyrolysis are feasible, the challenge of PU chemical
recycling is in the varying mixture and composition of its
monomers. Here, we propose a biotechnological route to
utilize PU hydrolysate as a carbon source for a defined
microbial mixed culture. The mixed culture consists of
dedicated microbes, each trained to utilize a single PU
monomer and further engineered to produce valuable products.
While three Pseudomonas putida KT2440 derivatives utilized
adipic acid, 1,4-butanediol, and ethylene glycol,
respectively, a recently described Pseudomonas sp. TDA1 used
2,4-toluenediamine (TDA) as a sole carbon source. However,
TDA clearly inhibited mixed substrate utilization by the
mixed culture, and it also has a high intrinsic value.
Therefore, TDA reactive extraction before PU monomer
utilization was established, allowing full utilization of
the remaining PU monomers as carbon sources for rhamnolipid
production. The results highlight the potential of
(bio)technological plastic upcycling.},
