What does the published scientific research say about Geobacillus thermoglucosidasius?

Geobacillus thermoglucosidasius — also classified as Parageobacillus thermoglucosidasius, and previously listed as Bacillus thermoglucosidasius or Geobacillus thermoglucosidans — is a thermophilic soil bacterium with one PubMed article referencing it in a plant-input context as of this index.

That study (PMID 40471713) investigated how Parageobacillus thermoglucosidasius survives in temperate soils despite its thermophilic nature. Using a hydroponic system with tomato plants, researchers reported that the rhizosphere environment increased bacterial survival at 20–25°C by over 23-fold compared to controls. Rhizosphere exudates alone boosted survival in pure cultures at 25°C by up to twofold, with the exudate composition characterized through targeted metabolomics.
