What does the published scientific research say about Frateuria aurantia?

Frateuria aurantia — also listed in the literature as Acetobacter aurantius and Acetobacter aurantium — is referenced in 7 PubMed articles in plant-input contexts. The peer-reviewed record positions it primarily as a potassium-mobilizing plant growth-promoting rhizobacterium (PGPR) applied in biofertilizer consortia, and it appears as a characterized strain in commercial inoculant quality-control research.

Postharvest research on white button mushroom (Agaricus bisporus) reported that Frateuria aurantia treatment reduced weight loss and maintained cap firmness, total phenolic content, and antioxidant capacity during shelf life, with the authors describing it as a promising treatment for postharvest quality. In a wheat (Triticum aestivum) field trial, it was applied as part of a consortium with Rhizophagus irregularis and Bacillus megaterium; that study reported enhanced plant growth and nitrogen accumulation, with grain yield gains of 1–4% over uninoculated controls cited in the literature.

A chickpea study tested a commercial Frateuria aurantia formulation (Symbion-K) alongside locally isolated PGPB; local isolates outperformed Symbion-K on shoot length and biomass, though most PGPB treatments enhanced macro- and micronutrient content in shoots. F. aurantia has also been characterized as a strain in eucalyptus biogrowth promoter product quality-control research. Several of the 7 records reference the organism for taxonomic comparison rather than as a direct application subject.
