Laboratory experiment shows that bacteria really eat and digest plastic.
The bacterium Rhodococcus ruber eats and actually digests plastic. This has been shown in laboratory experiments by PhD student Maaike Goudriaan at Royal Netherlands Institute for Sea Research (NIOZ). Based on a model study with plastic in artificial seawater in the lab, Goudriaan calculated that bacteria can break down about one percent of the fed plastic per year into CO2 and other harmless substances. “But,” Goudriaan emphasizes, “this is certainly not a solution to the problem of the plastic soup …
