Very cool if true

TheRecord.com – CanadaWorld – WCI student isolates microbe that lunches on plastic bags

Next, Burd tried mixing his most effective strain with the others. He found strains one and two together produced a 32 per cent weight loss in his plastic strips. His theory is strain one helps strain two reproduce.

Tests to identify the strains found strain two was Sphingomonas bacteria and the helper was Pseudomonas.

A researcher in Ireland has found Pseudomonas is capable of degrading polystyrene, but as far as Burd and his teacher Mark Menhennet know — and they’ve looked — Burd’s research on polyethelene plastic bags is a first.

Next, Burd tested his strains’ effectiveness at different temperatures, concentrations and with the addition of sodium acetate as a ready source of carbon to help bacteria grow.

At 37 degrees and optimal bacterial concentration, with a bit of sodium acetate thrown in, Burd achieved 43 per cent degradation within six weeks.

The plastic he fished out then was visibly clearer and more brittle, and Burd guesses after six more weeks, it would be gone. He hasn’t tried that yet.

Should be easy enough to duplicate.

And the nice thing is that the reaction won’t move fast enough at dry room temperature to destroy civilization…
