ABSTRACT
Transposon, Tn917, carried on pTV1 plasmid has been used successfully to mutagenise Bacillus brevis. The transposon showed preference for insertion at an "aro" site. A second insertional event after elimination of the preferred site with ethidium bromide/acridine orange treatment has permitted isolation of Gln- mutants in B. brevis.
