Abstract

The invention relates to a transposon consisting of a fragment of the R plasmid pCxM82B from Corynebacterium xerosis DSM 5021, to mobilizable, non-self-transferrable vectors which contain this transposon, and to methods for the mutagenesis of gram-positive bacteria by means of the transfer of these vectors and the generation of auxotrophic mutants.
