Cadiz, 6A: Winogradsky column biotechnology group A6, 1st and 2nd week.

Hello, we are a group of students of biotechnology and we have done as a practical microbiology, one Winogradsky column.
The sediments of the Winogradsky column were collected from a lagoon close to the faculty of science.The date on which began the experiment was 04/03/2015. The material that has been used in the preparation of the column has been:
- NaCl
- Engine Oil
- Starch
- FeSO4
- CaCO3
- Pieces of paper

The mixture is first prepared by throwing a little of each component and stirring, then added the rest and is returned to mix. The clay leaving already ready to be introduced in the bottle. The volume of sediment is three quarters of the bottle. The water that was added was collected from the same lagoon as the sediment. The column is in a room near the window, giving you the light of the sun, but does not directly. Always with the same area to light and the other in the shade. We add many different components to see which of the mircroorganismos are more likely to develop. We hope to see sulfate-reducing, iron-oxidizing bacteria, besides oil eating bacteria and facilitate obtaining carbon CaCO3 and starch.

We can skip the first week because the most important thing that has happened in the death of the worms had.


In the second week, the part that is the sun has taken a green brown traces along the whole bottle. On the other hand the private part of the sun has taken a grayish tone.

                                             Here we can see the area that faces to sunlight



                                 Furthermore, this is the part of the column is not exposed to light.



The column is always in this position, the blue arrows that appear at the top it is to know that area should expose the light if you move home from another member of the group.


PS: Sorry I took so long to join this blog and upload the data on my column.
