The accelerated pace of industrialization and urbanization has a significant impact on the environment. Population development in an area will increase the demand for producing daily needs such as fuel, cosmetics, health equipment, and clothing. This increase has directly proportional consequences to the production of waste generated, especially in water and soil. This pollution is still a challenge for the near future. One potential alternatif is to use the laccase enzyme to degrade Polyaromatic Hydrocarbons (PAHs) in the environment. Laccase enzyme is a polyphenol oxidase belonging to the multicopper oxidase family characterized by the presence of a copper atom upon activation. These enzymes can oxidize various aromatic and aliphatic molecules that include reducing oxygen molecules to water. Plants, insects, bacteria, and fungi could secrete laccases, but the white-rot fungi group produces the highest production rates. This review uses literature studies to collect data on degradation by the laccase enzyme on Total Petroleum Hydrocarbon (TPH) contaminants, pharmaceuticals and hormones, and dyes. The high potential for TPH and dye degradation by laccase that can be biodegradable at low enzyme activity (<200 U/L), viable degradation time (<1 hour on dye, <28 days on TPH), and a high degradation efficiency (>80%).
