Abstract : Microbial biofilms of varied composition and thickness develop on all surfaces in contact with aqueous environments, a process known as. biofouling. Microorganisms are organisms that cannot be seen as individuals with the unaided human eye. Microorganisms use polysaccharides to cement themselves to surfaces, grow, reproduce, and produce more extracellular polymers. Biofilms contain immobilized cells embedded in an absorptive and porous organic polymer matrix of microbial origin. As a result, biofilms consist of a large percentage of adsorbed and entrapped materials, including solutes, heavy metals, and inorganic particles, such as silt and clay, in addition to the cellular constituents.
