Evidence of Iron Bacteria in October 2016—2


November 12, 2016

Sometimes a shadow reveals a less-visible Leptothrix discophora film. Someone explained to me why this happens, but I’m afraid I didn’t quite get it. Perhaps one of you knows and can explain it again?

  1. 🙂 I fear that even the explanation would be hard for me to follow! But I wonder if it has anything to do with the quality of light in shadow being more blue, and light in sunlight being more yellow.

    • Hm. Don’t know, but I don’t think so. Wonder where I put that other explanation . . .

  2. The colour is there but it takes a shadow to reveal it.

      • I have no idea unfortunately unless it could be something to do with whether light is polarized or not
