Peron, N., Cagna, A., Valade, M., Marchal, R., Maujean, A., Robillard, B., Aguie-Beghin, V., & Douillard, R. (2000). Horizontal gene transfer occurs more efficiently in biofilms than in suspended cells because cells are in contact with each other. The function of the wash step is to ensure that the cleaning agent makes contact with the soil on the surface, to remove soil from the surface and keep it away from the surface. Activities that take place here include washing, cutting, measuring, and mixing ingredients. This is a 4 step process that removes food waste, dirt, grease and destroys food-borne disease pathogens. Organisms in multispecies are not randomly organized, but rather arrange themselves in a way to benefit the most.
