Hey everyone
To
prepare the Winogradsky Column we took some soil from the San Pedro River and
mixed it with paper and 30g of NaCl. We prepared 2 bottles with the objective
of comparing the results after storing them in different conditions. During the
first 5 weeks, both bottles were exposed to direct sunlight on one side in an
aerobic, hypertonic environment, in order to see where different types of
microorganisms decided to locate themselves. After these 5 weeks, one of them
was switched to a place without sunlight, in the interest of visualising the
changes that occur on existing microorganisms when conditions are modified.
We will keep you informed.
