Group 6A, After a week

After a week we only can aprecciate three deposited sediments in function of the microorganism:

  • At the top of the column it turned to a brown colour and a bit green, it can be due to aerobic bacterias growing on it.
  • In the middle we can se a black zone, it can be because of nonsulfur photosynthetic bacteria.
  • At the bottom we can observe a gray zone where a big bubble it can be produced by microorgasim which have a big fermentative capacity.

    "At the top of the column it turned to a brown colour and a bit green, it can be due to aerobic bacterias growing on it."
    Which aerobic bacteria are green?

    "In the middle we can se a black zone, it can be because of nonsulfur photosynthetic bacteria."
    Which is the metabolism of these bacteria? What produces the black colour?


    "At the bottom we can observe a gray zone where a big bubble it can be produced by microorgasim which have a big fermentative capacity."
    So what is this bubble made from?
