When was the first bacterial biofilm described?
Quick Answer
Biofilms were recognized in the 20th century, with major scientific descriptions emerging in the 1970s and 1980s. They are communities of bacteria attached to surfaces in a slimy matrix.
The Full Story
Although surface-attached microbial communities were observed earlier, biofilms became a major scientific concept in the 1970s and 1980s. Researchers showed that bacteria in these communities behave differently from free-floating cells and can be more resistant to cleaning, antibiotics, and immune attack. The idea transformed thinking about dental plaque, medical device infections, and natural microbial ecosystems. Biofilm research is now central to environmental microbiology and infection control.
