Bacterial Biofilms: Live Chat with Rob Hull

Biofilms form when bacteria adhere to a surface in a watery environment and secrete a slimy, glue-like substance. This substance forms a matrix that helps the bacteria stick to different types of material, including fabric, and provides them with environmental protection. The bacterial cells then form a colony, or group, within the matrix. Biofilms can …
