Hi! We are
María, Cristina and Ara, students of biotechnology. We will show you our
experiment of Winogradsky column during this quarter.
In our
column, we add 20 g of mud from Rio San Pedro. We have focused on the
production of halophilic bacteria, that is to say that our bacteria will grow
in a very high percentage of salt. Exactly, we add 1,2 g of NaCl. Moreover, we
add 0,3 g of CaSO4 as a sulphate source and 0,3 g of cellulose
(paper) as a carbon source for our bacteria. Finally, we add 30 g of mud more,
22 g of sand and 1.99 g of NaCl more (we have put a lot of mud and just a bit
of sand). We wait some months to be able to see our results!
We haven't taken photos of our column in its first state, but later we will upload some of them.
