US Patent 9796957 Genetically modified diazotrophs and methods of using same

This disclosure describes a genetically-modified diazotrophic microbe and methods that involve the genetically-modified diazotrophic microbe. Generally, the diazotrophic microbe is modified to excrete a nitrogen-containing compound in an amount greater than a comparable control diazotrophic microbe. The genetically-modified diazotrophic microbe can be co-cultured with a non-diazotroph and increase the growth of the non-diazotroph.
