What does the published scientific research say about Stutzerimonas stutzeri?

Eight PubMed articles index Stutzerimonas stutzeri — also known by its earlier name Pseudomonas stutzeri — in plant-input research. The peer-reviewed literature centers heavily on nitrogen fixation: strains A1501 and DSM4166 carry a conserved nitrogen fixation island acquired via horizontal gene transfer, and the sequenced strain MBI-RS3 is reported in the literature to enhance plant growth through nitrogen fixation, phosphate solubilization, and phytohormone production.

Plant growth-promoting research on Stutzerimonas stutzeri extends beyond nitrogen. Rhizosphere isolate AUMC B-503 is cited in peer-reviewed research for IAA and HCN production, phosphate solubilization, and inhibition of Bipolaris oryzae — the fungus behind rice brown spot disease — under controlled conditions. The authors note that biosafety and regulatory evaluations remain prerequisites before field application. Separately, strain WA4 is reported to support crop growth and heavy-metal phytoextraction in coal fly ash-contaminated soil.
