細菌は、ネバネバした物質を分泌し、小さなコロニーを形成する。さらにそのコロニーは、違う種類の菌類や藻類、アメーバーなどの原生動物から金属の破片や腐食物などを含みながら大きな形になっていき、「バイオフィルム」になる。バイオフィルム内には栄養分や少ない酸素を効率よく運搬するシステムが出来ている。環境によってその構造や内部の構成物は大きく異なるが、有機物を分解してバイオフィルム内部の菌を守るために抗菌性の物質を出すことが知られている。また、バイオフィルムは有害な重金属をバイオフィルムの栄養分に変えてしまう能力がある。
河川の自浄作用に応用できる。毒性がある物質の影響を受けずに廃棄物や廃液の分解をする技術に応用できる。排水を燃料とするバイオフィルムを利用した微生物燃料電池の開発に応用できる。排水処理と同時に電力を生産できる発電施設の開発に応用できる。宇宙飛行士の排泄物から発電ができる技術に応用できる。
