Marine scientists discovered an ocean-borne fungus chomping through plastic trash in the Great Pacific Garbage Patch.

    I would really like to know what’s the resulting materials after the breaking down, but the article doesn’t say :(

      Well, given what we know about most commercial plastics, which are all derived from oil/complex hydrocarbons, the consumed plastic could be broken down into condensed carbon? Or would it be carbon gases? I’m speculating based on just what I know about plastics, what they are and how they’re made.

        The fungi are likely oxidizing the plastic to CO2, probably via many metabolic intermediates. This is likely driven by the fact that plastics are chemically reduced - a rich source of chemical potential energy. Accessing that energy requires enzymatic conversion to a less reduced state, culminating in the fully oxidized CO2 molecule.
