A biofilm is any group of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPS).
The cell capsule is a very large structure of some prokaryotic cells, such as bacterial cells. A true capsule is a discrete detectable layer of polysaccharides deposited outside the cell wall. A less discrete structure or matrix which embeds the cells is a called a slime layer or a biofilm. The capsule found in bacteria called a glycocalyx. It lies outside the cell envelope of bacteria and is thus deemed part of the outer envelope of a bacterial cell.
