Repair of ozone-induced DNA lesions in Escherichia coli B cells.
Alkaline sucrose gradient sedimentation indicates that ozone can produce DNA single- and double-strand breaks in wild-type E. coli and ozone-sensitive mutant MQ1844(ozrB). Another type of DNA damage repaired only by the ozrB gene product may also be responsible for the killing effect of ozone on E. coli cells.
