John W. Costerton

John W. Costerton was a pioneering microbiologist known for his work on biofilms—complex communities of microorganisms that adhere to surfaces. His research helped us understand how bacteria form protective layers, which can impact medical devices, pipes, and natural environments. By uncovering these structures, Costerton advanced techniques to prevent and treat infections and improve industrial processes. His innovations have had a lasting influence on microbiology, emphasizing the importance of microbial communities in health and industry.
