Abstract
A recombination-deficient mutant of Streptococcus lactis ML3 designated MMS36 was isolated on the basis of its sensitivity to methyl methanesulfonate. This mutant also displayed sensitivity to UV irradiation. The inability of MMS36 to mediate homologous recombination was demonstrated by transduction of plasmid-linked lactose fermenting ability but not chromosomally mediated streptomycin resistance.
