In a previous report curing of prophage in Staphylococcus aureus by treatment with 8-methoxypsoralen plus near-UV (365 nm) radiation was described. In the present work the use of angelicin and 4,5',8-trimethylpsoralen and repeated irradiation show that monoadducts and DNA interstrand cross-links formed by furocoumarin photoaddition are involved in the curing of the prophage responsible for the suppression of the lipolytic activity in a putative repair proficient strain of Staphylococcus aureus.
