WebSep 6, 2010 · SC3 is secreted into the medium and will self-assemble at the interface between the medium and the air. This is accompanied by a decrease of the water surface tension from 72 to 24 mJ·m −2 . A strain lacking SC3 (ΔSC3) reduces the surface tension less dramatically and therefore forms only a few aerial hyphae [19,25]. Hyphae that grow … how to screenshare on flipgridWebA surfactant, at its most basic, is a substance that is designed to reduce the surface tension of a liquid. For many operations in manufacturing processes, it is necessary for a liquid to spread out and wet a surface.

The … WebSep 3, 2015 · The polar end of the surfactant is attracted to the polar water molecule. When enough surfactant molecules attach to a water molecule, it gets covered in surfactant and forms a unit. These units have a weaker force of attraction because only the non polar head of the surfactant is exposed thereby lowering the surface tension.
