Καλημέρα!, Buenos dias!, Good morning!

We have our columns up and running from this morning!!

In total we have 18 columns

Numbers 2, 4, 6, 8, 12, 14, 16 have 2/3 sediment + 1/3 water, incubated in light
Numbers: 1, 3, 5, 7, 11, 13, 15, have 2/3 sediment + 1/3 water, incubated in darkness

Number 10 has have 2/3 sediment + 1/3 water + full-fat milk, incubated in light
Number 9 has have 2/3 sediment + 1/3 water + full-fat milk, incubated in darkness

Number 18 has have 1/10 sediment + 9/10 water, incubated in light
Number 17 has have 1/10 sediment + 9/10 water, incubated in darkness



  1. Ok ok you are more organised than us... :-) We let the spanish enthusiastic southern spirit to get hold of us.

    Hey spanish team, these guys are incubating some columns in the dark. Why? What are they trying exactly to do?

    Good luck, Volos.


  2. South united, united in the south!! This is the 9th year we are running the Winogradsky columns, we have sorted out the pitfalls!
    Darkness .... ok, this is an easy one, Sokratis. But why add milk? What should we expect in these columns?

  3. We are green in this... We hope we will get better but we like organised improvising. :-)

    Let' s see... What will you get? Apart from a terrible smell.

    This week we put some Milk agar plates to see if our bacteria will grow on casein. What is in the milk? Hey guys, can you help me?


  4. I woke up with a new idea... If you are not interested in protein degradation, or lipid degradation (since you used full fat milk, we used skimmed milk) could it be related to antibiotics?

    You have got me wondering...
