Definition: Naphthalene is a chemical compound with the formula C6H5NH2, which is found in plants and algae. It has been used for centuries as a natural disinfectant, but its use has declined due to environmental concerns about its potential impact on aquatic life. Naphthalene-degrading enzymes are designed to degrade naphthalene into other compounds, potentially reducing the amount of naphthalene available for use in synthetic products or as a byproduct.
