Enzymatic hydroxylation of polypropylene (PP) was investigated in order to increase hydrophilicity. A mutant (139-3) of the P450monooxygenase from Bacillus megaterium expressed in E. coli DH5α was purified using anion exchange chromatography. Hydroxylation of PP fabrics led to a dramatic increase of hydrophilicity as indicated by a water drop dissipation time of below 1 s compared to the hydrophobic reference m...
