Abstract

Characterization of biogenic iron oxide sheaths produced by Leptothrix ochracea (L. ochracea) was investigated. The sheaths had average inner- and outer-diameters of 1.08 ± 0.15 and 1.35 ± 0.14 μm, respectively. Their length ranged from 10-2000 μm. Outer and inner surface of each sheath were composed of fibrous and spherical particles, respectively. The width of fibrous particles was approx. 20 nm, while the diameter of spherical particles was 20-120 nm. The chemical composition of the sheaths was Fe: Si: P = 73: 22: 5 with the exception of H and O. The sheaths had similar structure to that of 2-line ferrihydrite.
