In order to cloning of the nif genes of Enterobacter agglomerans NFB-264, the digested total DNA of the strain was ligated to pBR 322 and transformed into E. coli. Through the negative selection and colony hybridization, the transformants were obtained. The recombinant plasmids, pNEL 10 and pNES 20 were extracted from these transformants. It was known from Southern hybridization that pNEL 10 contained the 12 Mdal foreign DNA fragment hybridized with nif Q-X probe and pNES 20 included the 5 Mdal foreign DNA fragment hybridized with nif NE and nif YK probe.
