Has anyone experience setting up Winogradsky colums using only
water? Can you get a stratified column of anerobic bacteria grwoing in a
column of water in the same way that you can with a column of mud? I am
trying by building a small classical column, about 25% of the total
volume of the column, (using mud mixed with egg or wood chips or paper)
and the rest of the column water collected with the mud. So far, about a
week no luck.
I am hoping the colonies would be more visible and perhaps we could
sample more easily, using a thin plastic tube, used to cover fluorescent
light bulbs.
Any ideas or suggestions?
