Most waste nitrile rubber (wNBR) is disposed of through incineration and landfill. Thus, a development of a new recycling method is desired. In this study, we focused on a development of a biochemical recycling process for wNBR. We explored enzyme genes involved in the assimilation of wNBR by an NBR-degrading actinomycete Gordonia sp. strain J1A. In this presentation, we report on enzyme genes predicted to degrade sulfur cross-linking and plasticizers in NBR products. Furthermore, a hypothetical pathway leading to β-oxidation of aldehydes produced by enzymatic degradation of NBR will be presented.
