Biodegradability of surfactants

Surfactants are used in large amounts in detergents and many surfactants are toxic to aquatic organisms. It is therefore relevant to avoid accumulation of them in the environment. Many surfactants are degradeable under aerobic conditions (with oxygen). This requirement also require the surfactants to be degradeable under anaerobic condition (without oxygen).
