[Extraction of a broad range of metals from sewage in the city of Kyiv by mixed microbe communities].
Accumulation of a wide range of metals by the "mixed microbe communities" (MMC) from Kyiv sewage treated in the air tank has been studied. MMC is a mixture of one or more synthrophical associations, such as microorganisms of fermented metantank deposit and cow manure. The exposure being 48 h and weight ratio of the phases MMC : sewage being 1:50, MMC lower the concentration of Ca, Fe, Zn, Cc, Au in sewage by 1 order; Cr, Mn, Co, Ag, Cd, Ba, Sm, Hf, Th--by 2 orders; Sc, Sb, La--by 3 orders. MMC may be used efficiently for deep tertiary treatment of sewage for toxical heavy metals, for extraction of rare-earth and non-ferrous metals from superdiluted solutions and industrial sewage.
