Teen Discovers Plastic-Decomposing Bacteria 209

Posted by ScuttleMonkey 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.

      Actually, bacteria mutate fairly quickly as it is. First of all, they don't have nearly the same level of DNA repair ability that eukaryotes (that's all multi-celled creatures and some single-celled) do. Second of all, their sheer numbers are enormous. In a small container, populations many orders of magnitude larger than the human population, can be grown. So out of the huge populations alone, you can expect a much larger overall mutation count.

      Finally, different species of bacteria can share genetic material (DNA plasmids) through a type of "mating" called conjugation, allowing species to trade traits with other species.

      Any mutations that makes them more efficient reproducers and better able to create energy from their environment is likely to ensure survival and ability to out-reproduce their peers.

      Through these various methods, you should get a fairly high rate of mutation. Adding radiation may actually be detrimental to the overall success of the intent. Mutations tend to be detrimental, so if you increase the rate too much, you end up killing them off too fast. You also increase the risk of killing off the small populations with the new positive mutations you want, before they have a chance to spread.

      It wouldn't surprise me if you went digging through a bunch of dumps that have been covered up years ago, to find bacteria that have evolved to eat some of that garbage. I suspect that the time required for our garbage to decompose is actually lower than we predict since we don't really factor in the possibility of bacterial mutations which can make them good consumers of the garbage. I suspect these mutations will happen in far less time than the natural decomposition period of the materials in question.

        *sigh* It's called a positive feedback loop. Increased temperatures do result in increased CO2 levels. Increased CO2 levels then result in increased temperatures. And thus the cycle continues upwards until something causes it to stop. The real big giveaway is that the temperature increase always accelerates as CO2 concentrations goes up.

        This is a simple laboratory experiment that anyone can do. Heck, they did it on MythBusters.

        And yes, it's true that natural processes put out a lot more CO2 than humans do. That's not the point. Natural processes are more or less balanced; what nature puts out, nature absorbs. What we are doing is upsetting the balance so that there isn't enough capacity. One of Dicken's characters said "Annual income 20 pounds, annual expenditure 19 six, result happiness. Annual income 20 pounds, annual expenditure 20 pounds ought and six, result misery." - his point was that all you need to do is live just a little beyond your means to cause big problems.

        Heck, it doesn't even matter if we _are_ the main cause or not. If we're not the main cause, we're still contributing to the problem at least a bit. Personally, I'd rather be the cause - it would imply that we could fix it.
