(2018): Laccase catalyzed elimination of morphine from aqueous systems
NEW BIOTECHNOL. 2018; 42: 19-25. FullText FullText_BOKU

Pharmaceuticals contaminate the environment for several reasons, including metabolic excretion after intake, industrial waste and improper disposal. The narcotic drug morphine is commonly utilized for chronic pain management, and the distribution of morphine in aqueous systems and in waste waters is of high concern. Here, the removal of morphine by a laccase from Myceliophthora thermophila both in its free form as well as immobilized on Accurel MP1000 beads was investigated. Complete morphine elimination was achieved within 30 min for the free and the immobilized enzyme (70% bound protein) for concentrations between 1 and 1,000 mg L-1 according to LC-TOF mass spectrometry analysis. Higher morphine concentrations up to 60 g L-1 were also tested and total elimination was achieved within 6 h. Therefore, laccases are ideal candidates for removing morphine from aqueous systems.
