First day: Elaboration of the column.
To make the Winogradksy's column, we need a few 2 L plastic
bottle and are filled with a mixture of mud from "Río San Pedro" and
sea water. As a source of carbon we add paper, NaCl and CaSO4 . We
prepared well, exactly the same two bottle, one put it in the light of the sun
and another in the dark.
