Abstract:Biofilms are sessile microbial communities growing on surfaces, which are encased in some self-produced polysaccharides, proteins, lipids, and extracellular DNA. Biofilms were often supposed to be potentially destructive to the environment and detrimental to medical, food, and marine industries due to their tough structures and difficult to remove from surface. However, the biofilms formed by bacteria such as Bacillus can be widely used in agriculture, food, medicine, environment and other fields, and can promote biofilm formation by interfering with quorum sensing and improving the environmental conditions of culture. The author summarizes the process of biofilm formation, focuses on the application of biofilms in the pre-harvest and post-harvest biological control of agricultural products, and explains some strategies currently used to promote the formation of biofilms, which aims to provide reference for further development and application of biofilms in the fields of agriculture and food.
