Schematic illustration of the six stages of cellulolytic biofilm formation on cellulose surface observed from this study. i.e., 1) single cell attachment to the substrate; 2) cell growth and division 3) inverted colony formation; 4) crater-like depression formation due to degradation of the cellulose substrate; 5) fusion of the depressions; and 6) homogenous biofilm formation.
