Biofilms are Everywhere

Bacteria are often thought of as solitary organisms, but in nature, the majority of microorganisms actually live together in larger numbers attached to a surface that is referred to as a “biofilm.”

A mature biofilm can be quite complex - have layers, clumps and ridges or microcolonies can be arranged into stalks or mushroom-like formations. The organisms in biofilm may be a single species or there may be a diverse group of microbes distributed in various regions of the biofilm. Surrounding them is a matrix made up of sugars, DNA, and proteins, which are often (scientifically) referred to as slime – this helps them adhere to the surface and also offers protection from environmental stressors.

Dental plaque is a biofilm on our teeth (Norwex has the Silvercare Toothbrush). Biofilm on our fruits and vegetables can be effectively removed with Norwex Fresh Wash. Simply soak in a dilution of 5 sprays/cup for a couple of minutes, and for maximum benefit, follow with a wipe of a microfiber cloth (TIP - choose one colour from the Antibac Kitchen Pack for this purpose).
