Biofilms definition microbiology
WebBiofilms tend to form in aqueous environments whenever planktonic cells (free-floating microorganisms) attach and adhere to surfaces (called substrata) and/or to each other. Providing that the physicochemical conditions are favorable (pH, temperature, nutrients), a community of adherent microorganisms (mono- or mixed species) will start growing. A biofilm is a thick layer of prokaryotic organisms that have aggregated to form a colony. The colony attaches to a surface with a slime layer which aids in protecting the microorganisms. There are a number of reasons why biofilms are formed, all of which promote growth and survival or the microorganisms. … See more A microbial biofilm is made up of many prokaryotic organisms that combine to form a colony. The colony is adhered to a surface and coated with a polysaccharide layer (or slime layer). … See more The microorganisms in a biofilm aggregate to form a colony for metabolic cooperation.
