Everything is everywhere. The environment selects. Practical applications possible out of winogradsky column like using it as a universal enrichment medium for all microbes to grow as they are and also to isolate and evolve purpose based microbes for degradation studies. Nature is just a hidden Winogradsky column. Thus whatever mechanisms that underlies degradation in field is the same when simulated inside a winogradsky column. So we simulate all the constraints that face the degradation of hard substrates and the mechanisms inside this column to achieve results that can be immediately applied in field, without need of elaborate experimentation with artificial culture medium.
