  • Three $NIf^{-}$ -mutants were isolated from Enterbacter agglomerans 339 through the transposon umtagenesis using a RP4-mobilising system for its nif-gene characterization. All mutants hadn't acetylene-reduction ability. Then we confirmed that Tn5 was inserted into all conserved nif-plasmids through the Southern Hybridization.
