Bacteria eats plastic

“Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms. If those microorganisms, as well as the optimal conditions for their growth, could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he ground plastic bags into a powder and concocted a solution of household chemicals, yeast and tap water to encourage microbe growth. Then he added the plastic powder and let the microbes work their magic for three months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control.
Sure enough, the plastic exposed to the live bacteria was 17 percent lighter than the control after six weeks. Once Burd examined the most effective strains of bacteria, he was able to isolate two types—Sphingomonas and Pseudomonas—as the plastic munchers. At 37 degrees and optimal bacterial concentration, the microbes had consumed 43 percent of a plastic sample within six weeks.”
