Which of the following is a characteristic feature of biofilms?

• A. Single-cell organisms thriving independently
• B. Increased susceptibility to antibiotics
• C. Formation of a protective extracellular matrix
• D. Rapid growth in nutrient-rich environments

Answer: (C)

A characteristic feature of biofilms is the formation of a protective extracellular matrix. This matrix, composed of polysaccharides, proteins, and nucleic acids, helps to anchor the cells within the biofilm and provides a protective environment against various stresses, including antibiotics and the immune system. The extracellular matrix not only facilitates the structural integrity of the biofilm but also plays a crucial role in nutrient retention and communication among the microbial community. This matrix is essential for the survival and persistence of biofilms in diverse environments, allowing the microbes within to adhere to surfaces and retain moisture and nutrients, further enhancing the biofilm's resilience. Biofilms often develop on various surfaces, including medical devices and natural environments, demonstrating their significant role in both health and disease contexts.
