WebAbstract. Epilithon is the biofilm which develops on the surface of stones in aquatic habitats. It has a complex structure, consisting of algae, fungi and bacteria all held together within a polysaccharide matrix [18]. This matrix is secreted by the micro-organisms themselves and is a site of nutrient accumulation [15].
