What benefits of Streptomyces griseus have been cited in the scientific literature?
On plant growth, studies cite Streptomyces griseus as increasing chickpea biomass 1.2–2.0 fold. Consortia that included S. griseus strains were associated under field conditions with increases in nodule number (up to 25%), grain yield (up to 22%), and shoot, root, and seed weight — all reported in the literature, not regulatory endorsements.

2Potential claims from the literature
Reported to suppress plant fungal diseases through antifungal metabolite production and direct antagonism, including against Sclerotium rolfsii (collar rot) in chickpea, Phytophthora capsici, Fusarium oxysporum f. sp. fragariae in strawberry, and Fusarium oxysporum f. sp. ciceri (Fusarium wilt) in chickpea; a chitinase produced by S. griseus has been characterized as a potential biocontrol agent
Reported to promote plant growth in chickpea, increasing biomass 1.2–2.0 fold; consortia including S. griseus strains were associated with increased nodule number (up to 25%), nodule weight (up to 49%), leaf area (up to 37%), shoot weight (up to 35%), root weight (up to 23%), seed weight (up to 30%), and grain yield (up to 22%) under field conditions
