The accumulation of nanoparticles of colloidal silver with spherical shape in culture liquid of Azospirillum brasilense has been shown by transmission electron microscopy. Bacterial extracellular Mn-peroxidases were found to participate in silver reduction from silver nitrate with the formation of nanoparticles. A mechanism of extracellular biosynthesis of silver nanoparticles by A. brasilense bacteria was proposed
通过透射电子显微镜已证实，巴西固氮螺菌培养液中存在球形胶体银纳米颗粒的积累。研究发现，细菌胞外锰过氧化物酶参与了硝酸银中银的还原过程，并形成了纳米颗粒。提出了巴西固氮螺菌细菌胞外生物合成银纳米颗粒的机制
