A new function of graphene oxide emerges: inactivating phytopathogenic bacterium Xanthomonas oryzae pv. Oryzae
TL;DR: In this paper, the antibacterial activity of graphene suspended in different dispersants against Xanthomonas oryzae pv. was investigated, and the results showed that graphene oxide (GO) exhibits superior bactericidal effect even at extremely low dose in water (250μg/mL), almost killing 94.48% cells, in comparison to common bactericide bismerthiazol with only 13.3% mortality.
