Overall, this study presents observations related to slime-mediated motility on multiple scales (molecular, single-filament and colony), and integrates these findings into a coherent model for the relationship between the cellular organization and the behavior of the colony.
Lines 316–317: This model for slime secretion suggests that rather than slime being comprised of a single, long, polysaccharide, it is made of smaller subunits that are secreted in a step-wise fashion. The authors should connect this idea to the finding that pseudopilins appear to be part of the molecular machinery, as the model and the data are coherent on this point.
