Cool

Nylon, Yummy Nylon

Here's something I haven't seen before: The story of how a single mutation allowed a bacteria to digest nylon:

My favorite example of a mutation producing new information involves a Japanese bacterium that suffered a frame shift mutation that just happened to allow it to metabolize nylon waste. The new enzymes are very inefficient (having only 2% of the efficiency of the regular enzymes), but do afford the bacteria a whole new ecological niche. They don't work at all on the bacterium's original food - carbohydrates.
Naturally, this ability to digest nylon is "irreduceably complex": If you remove any one of the genes involved, it no longer works. Unfortunately for the IDists, we know exactly how a single genetic mutation gave rise to this ability.

1 This may well be th end of the tracksuit as we kow it.

2 It's proof that god hates nylon because of what it did to the wool, silk, and cotton industry.

3 Maybe the big G just has a problem with static cling.

4 Hmmm, didn't think of that. I do have one question regarding this new bug: All carbon based life forms must intake carbon in order to live, but if these new bugs eat nylon, do they chemically convert part of it to carbon, or do they simply become non-organic life forms? If we can make a life form that is non-organic, then the potential for new applications, such space and deep sea exploration by engineered biomechanical cyberbetic organisms, starts to sound less like sci-fi and more like possibility. Just think, no carbon means no need for oxygen, and though anaerobic carbon-based organisms have existed for a long time, they have remained very primative because if exposed to air they oxidize quickly and die. If a new organism could be built, one with a biomechanical brain and self repairing cellular structure that could ingest raw elements and survive brutal conditions, then we could literally flood the galaxy with them in order to perform basic tasks such as planetary surveys. The possibilities are endless.

5 I remind you of the X-Files episode in which folks were exposed to a silicon-based lifeform that caused their throats to explode......
I wonder what my tracksuit is thinking right now....

6 Actually, nylon is a polymer of C6H13NO (or something similar; there are a few different types of nylon). It's a hydrocarbon, not a silicone.
If there were bacteria that could digest silicones, that would be impressive.

7 I was simply bringing up the silicone lifeform for the purpose of making a joke.
I should eschew obfuscation.

8 Okay, but Improbulus Maximus seems to be a little confused.

9 Not confused, just carried away. Because of the way nylon is chemically structured, it is almost impervious to things that are highly destructive to straight organics, and so I was thinking beyond the immediate application. Chemistry isn't my strong suit, but then, Einstein failed math. Do NOT take that as me drawing a parallel either, just pointing out that imagination is important.

10 Okay, but I was confused.

11 What about those microbes that eat steel, check out how the Titanic is being eaten:
