The Winogradsky column, invented by Sergei Winogradsky, consists in a transparent cylinder for analyzing microbial life by observing how the metabolism of micro-organisms evolve over time in stratified layers. By producing a small closed ecosystem, the column enables observing how bacteria can survive by providing a temporal and spatial visualization of layers such as in ecology, microbiology.
