Teen Discovers Plastic-Decomposing Bacteria

Posted by ScuttleMonkey on from the here-comes-the-study-claiming-it-causes-cancer dept.

ganelo writes to tell us that 16-year-old Waterloo Collegiate Institute student Danel Burd has made quite a stir with his plastic-eating bacteria discovery. For his efforts Burd won top prize at a Canada-wide science fair claiming a $10,000 prize and a $20,000 scholarship. "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."

    You know what would be cool is instead of just saying ooh I wonder if it eats plastic too and finding out it does, though that's definitely stll amazing...put some bacteria that are at least close to maybe being able to eat X substance and put it on the surface of that substance and blast them with regular, mild radiation every day until some mutate until a colony mutates and starts eating the rubber/plastic/whatever. I've heard very little about forcing mutations randomly to try and get a given result but it seems like a good idea to me. I mean if this kid had found that the bacteria couldn't eat plastic, I doubt anyone would have given him the funding and stuff to try and alter them so they do. And yes, before anyone posts it, keep the test area damn well sealed too so supergerms don't get out (duh!).

      a similar technique to what you describe has already been used to generate a strain of bacteria capable of cleaning coal of various hydrocarbons. the basic idea is that you can breed bacteria and put a selective pressure on them while slowly changing the chemical environment they live in. in the case of coal, you start with oil digesting bacteria and slowly acclimate them to larger quantities of hydrocarbons typically found in the presence of coal while lowering the concentration of the original "oil" hydrocarbons. it is my understanding that the process I am referring to has been patented although I do not believe that radiation/mutagens were used in the breeding process. so in principle your idea, though not new, would/does work and is being used to some extent.

      This reminds me of that episode of sliders where a bacteria created to eat plastic waste escapes and eats the worlds petrochemical supply.

    "...you came up with an answer to 29 million tons of non-biodegradeable plastic being added to landfills each year, so here's 10 grand. Yep, 10 big ones. Oh, and go get yourself a bit of education."
