Hello lovers of microbiology

We are going to explain how we made our Winogradsky column experiment. 

First of all, we mixed in a bucket river “San Pedro”’s sediments and river water.  Then, we added 0,5g of NaCO3 and a piece of paper (cellulose). Finally, we mixed river’s sand we the previous mix (if it is necesary we add a little bit o water, but trying to not make de mix a liquid).

Then, we introduced the mix in a big test tube, in our case, we added 0,25g of NaCl for encourage the development of halophilous bacteriums.  For making it funnier we did two test tubes with the same composition, but one of them will be in the oscurity and we put the other in the light so we expect that in the second tube we will find more fotosintetic bacteriums so we can apreciate the differences between both tests tubes. 
What will happen the next time we observe them?

On the right we can see first a photo of the column that goes on the dark in day 0 and above we can see a photo of the column that goes on the light in day 0. 
On the right, we see the same columns but after 7 days.
