Moreover, it has been formed a pink section where there are an opaque liquid with little sediments n the upper part. This is because of the metabolic activity of the microorganisms. This pink part appeared two weeks before the photograph was taken.

UCA_5B_2: Day 15 (Germán López Toledo & Miguel Bruzón Lobatón)
Fifteen days after we created our Winogradsky Column, it has been occurred a lot of changes. Firstly, we could see a big bubble of methane (that it is a proof of our excess of carbon and sulphate). We had to take a stike to go down the mud which was over the bubble in order to ease the gas exchange in the column. Excepting for this week, there was, at least, one a week. Bearing in mind the methane's bubble, when it was bursted, the surrounding's smell was the typical and awful one. Apart from this one, there was not anyone else. The whole black color is due to the excessive quantity of iron sulphate. This means a high level of anaerobic respiration.
Moreover, it has been formed a pink section where there are an opaque liquid with little sediments n the upper part. This is because of the metabolic activity of the microorganisms. This pink part appeared two weeks before the photograph was taken.
