Fig. 7: Phosphorus dissolution mechanisms derived from the one-cell organic-PSM genome of SSW7 (annotated as Cutibacterium spp.).

Two secreted phosphatases (ushA and MPP), three phosphatases proteins (ushA, PPE1 and PPE2), and the PstSCAB-PhoU gene cluster are key components that underpin the strong organic-P solubilizing phenotype of SSW7 and related strains in the sewage.
