When Bacillus subtilis gets the chance, it establishes thick, gluey biofilms held together by a matrix of exopolysaccharides and protein. Once cells sense that there’s enough extracellular matrix, they switch over to sporulating and tend to localize themselves in aerial protrusions so they can ... Read More
