Additional file 4: of Genomic traits of Klebsiella oxytoca DSM 29614, an uncommon metal-nanoparticle producer strain isolated from acid mine drainages

Figure S1. K. oxytoca DSM 29614 grown in NaC (left) and in FeC medium (right) after 7 day of incubation at 30 °C. Figure S2. a,b) Production of ortorhomboidal struvite in the presence of Hg2+ (a) and Ag+ (b); both crystals precipitated in aerobic cultures of K. oxytoca DSM 29614. c,d) Micrographs of microcrystal of struvite by K. oxytoca DSM 29614 cells, grown in aerobic conditions in the presence of Pd2+ in transmission mode (c) and in fluorescence mode (d) with cells stained with DAPI. e) Micrographs of TEM of microcrystals of struvite coated by Pd2+.
