Significance of microbial biofilms in food industry: a review

اهمیت بیو‌فیلم‌های میکروبی در صنایع غذایی: باز‌نگری

ABSTRACT

In nature and food systems, microorganisms get attracted to solid surfaces conditioned with nutrients, that are sufficient for their viability and growth. These microorganisms initially are deposited on the surfaces and later get attached, grow and actively multiply to form a colony of cells. In this regard, the formation of organic polymers are essential which helps in the proper colonization of microorganisms (Allison and Sutherland, 1987). These mass of cells further become large enough to entrap organic and inorganic debris, nutrients and other microorganisms leading to the formation of a microbial biofilm. The term biofilm refers to the biologically active matrix of cells and extracellular substances in association with a solid surface (Bakke et al., 1984). However, according to Costerton et al. (1987) a biofilm is a functional consortium of microorganisms attached to a surface and is embedded in the extracellular polymeric substances (EPS) produced by the micro- organisms.
