Why do bacteria form a biofilms?

Bacteria form biofilms as a survival strategy that provides protection from environmental stresses, such as antibiotics, immune responses, and desiccation. By adhering to surfaces and each other, they create a structured community that enhances nutrient acquisition and waste management. Biofilms also facilitate communication and cooperation among bacterial cells, promoting genetic exchange and resilience. This complex lifestyle allows bacteria to thrive in diverse and challenging environments.
