Bhakitiriya biomass yakaunganidzwa kubva musheath-inogadzira mabhakitiriya eiyo genera Sphaerotilus neLeptothrix yakaunganidzwa kubva pakakwirira-gomo rechisikigo rukova rwemvura.Iyo yekutanga bumbiro uye oxide zvikamu zvezvigadzirwa mushure mekusarudzwa kurimwa kwebhakitiriya pamidhiya miviri yakasarudzika uchishandisa neutron activation analysis (NAA), electron microscopy (SEM, TEM), uye X-ray diffraction (XRD) yakadzidzwa.Iyo yakakwira yekupfumisa nhanho yesimbi yakaratidzwa neiyo NAA tekinoroji mune yakasimwa yakazvimiririra kana ichienzaniswa nereferenzi sampuli kubva kune zvakasikwa.Mhando nhatu dzesimbi oxide compounds dzakavambwa mushure mekurima muAdler's medium: lepidocrocite (γ-FeOOH), magnetite (Fe3O4), uye goethite (α-FeOOH).Kurimwa muIsolation medium kwakaburitsa chikamu chimwe chete, icho chegoethite, kusingasanganisire sampuro imwe ine huwandu hunosiyanisa hwelepidocrocite.XRD uye EM kuongorora kunoratidza kuti iyo biogenic oxides inosized.Chidzidzo chedu chinopa muenzaniso wemikana yenzira yebiotechnology yekuwana, pasi pemamiriro ekugadzira, huwandu hukuru hwesimbi-ine-zvigadzirwa zvinogona kuve zvekuwedzera kushandiswa mune yakakodzera nano- uye biotechnologies.
