Waste Nylon Describe Human Activity Resulted Evolution Populations

Flavobacterium in factory wastewater has evolved to digest nylon, an adaptation likely resulting from gene duplication and frameshift mutations, providing a nutritional advantage that was naturally selected.

Flavobacterium in factory wastewater has evolved to digest nylon, an adaptation likely resulting from gene duplication and frameshift mutations, providing a nutritional advantage that was naturally selected.

Front Describe how human activity has resulted in evolution in populations of Flavobacterium.
Back Flavobacterium:
  • Live in waste water of factories that produce nylon 6
  • They have evolved to digest nylon - beneficial for cleaning up factory waste
  • No other strain of Flavobacterium has nylonases 
  • It is thought that gene duplication + frameshift mutation led to tis adaptation, it was advantageous and therefore naturally selected bc it provides them with another source of nutrients
