modulates exopolysaccharide polymer length and the dynamics of biofilm development with a β-1,4-endoglucanase.

It is well established that exopolysaccharide (EPS) is an integral structural component of bacterial biofilms necessary for assembly and maintenance of the three-dimensional architecture of the biofilm. However, the process and role of EPS turnover within a developing biofilm is not fully understood. Here, we demonstrated that uses a self-produced endoglucanase to enzymatically process its own EPS to modulate EPS polymer length.
