Sliding

Sliding motility is a passive form of surface spreading that does not require an active motor but instead relies on surfactants to reduce surface tension, enabling the colony to spread away from the origin, driven by the outward pressure of cell growth. PubMed. Sliding can be observed in wild isolates of Bacillus subtilis not expressing or deleted for hag gene PubMed. Sliding requires surfactin production and the presence of potassium in the medium PubMed. Further, sliding requires various components that are related to biofilm formation PubMed.
