Winogradsky Column | Science | University of Waterloo
During the 1880s, microbiologist Sergei Winogradsky developed a column for studying different types of microorganisms that vary in their preference for oxygen and ability to use light for energy. Within the column, different gradients form based on the microbes that are active in that "strip", resulting in striking colour differences.
