“…3K ) genera have been shown to degrade lignin ( 72 , 95 ), which could give these organisms the capacity to degrade aromatic polymers, such as polyethylene and PC plastics, and their monomers ( 8 , 14 , 73 , 83 ). We were not able to find any published evidence that members of the Litorivivens genus can degrade aromatic hydrocarbons, but many members of the Gammaproteobacteria class are capable of degrading aromatic compounds, including members of the Paraburkholderia and Pelomonas genera discussed here ( 84 , 92 , 93 ). These results indicate that many groups of microorganisms identified in the enriched communities have been implicated previously in the degradation of diverse plastic types.…”
