UCA_1C_1: Day 1- THE CREATION OF A NEW WORLD

Hello!! We are Andrea, Alessia and Victoria. We are students of biotechnology in Cádiz and we will show you the changes that we see in our column of Winogradsky.

Rio San Pedro sediment + CaSO₄

We have decided to add only CaSO₄ to see which microorganisms can live in these conditions.

Firstly, we have mixed CaSO₄ with sea water and San Pedro River mud. This mixture has been added to a transparent tube which has been exposed to solar light for some weeks.

After a week, we can see that the column has a different color. This is because the organisms have begun to grow at the bottom of the tube. These organisms are anaerobic so they do not need oxygen to grow, they use the sulfate we had added.

After three weeks, we see how more organisms have grown near the surface. These organisms need other conditions to grow. They need oxygen in addition to sunlight. On the surface have grown filaments that look like “hairs”.
