Ibhaktiriya biomass eqokelelwe kwibhaktiriya eyenza i-sheath yohlobo lwe-Sphaerotilus kunye ne-Leptothrix yaqokelelwa kumthombo wamanzi wendalo okwintaba ephakamileyo.Umgaqo-siseko we-elemental kunye nezigaba ze-oxide zeemveliso emva kokulinywa okukhethiweyo kweebhaktheriya kumajelo amabini ahlukeneyo akhethiweyo usebenzisa uhlalutyo lwe-neutron activation (NAA), i-electron microscopy (SEM, TEM), kunye ne-X-ray diffraction (XRD) yafundwa.Umgangatho ophezulu wokutyebisa wentsimbi utyhilwe bubuchule be-NAA kwiindawo ezizimeleyo ezilinywayo xa kuthelekiswa nesampulu yereferensi evela kwindalo.Iintlobo ezintathu ze-iron oxide compounds zasekwa emva kokulima kwi-Adler medium: i-lepidocrocite (γ-FeOOH), i-magnetite (Fe3O4), kunye ne-goethite (α-FeOOH).Ukulima kwindawo yoKwahlula kuvelise isigaba esinye, eso se-goethite, ngaphandle kwesampulu enye enexabiso elahlulakalayo le-lepidocrocite.Uphando lwe-XRD kunye ne-EM lubonisa ukuba i-biogenic oxides i-nanosized.Uphononongo lwethu lubonisa amathuba endlela ye-biotechnology ekufumaneni, phantsi kweemeko zokwenza, ubuninzi beemveliso eziqulathe isinyithi ezinokuthi zisetyenziswe ngakumbi kwi-nano- kunye ne-biotechnologies efanelekileyo.
