Four archaeal metagenome-assembled genomes (MAGs) were discovered in a polar upwelling zone in the Southern Ocean. These archaea contain genes encoding enzymes involved in the degradation of PET and PHB plastics.
Here, we present four archaeal metagenome-assembled genomes (MAGs) (three Thaumarchaeota MAGs and one Thermoplasmatota MAG) from a polar upwelling zone in the Southern Ocean. These archaea harbor putative genes encoding enzymes such as polyethylene terephthalate (PET) hydrolases (PETases) and polyhydroxybutyrate (PHB) depolymerases, which are associated with microbial degradation of PET and PHB plastics.
