Summary: The accumulation of antimony by rice is a severe threat to exposed populations. Previous studies showed that dry cultivation could decrease Sb uptake by rice. Microorganisms play an important role in regulating Sb mobility in rice paddies. Aerobic conditions led to a significant decrease in Sb uptake by rice compared to anaerobic conditions, possibly due to variations in microbial communities and redox environments.

It shows that As(III) oxidation can couple with nitrate reduction, mainly catalyzed by microorganisms containing aioA genes, while As(V) reduction is facilitated by microorganisms with arrA genes. Acidovorax, Hydrogenophaga, and Ramlibacter are the putative nitrate-dependent As(III) oxidizers, and Deinococcus and Serratia are the putative respiratory As(V) reducers.
