    Sulfur colloids as temporary energy reservoirs for Thiobacillus ferrooxidans during pyrite oxidation (1995)
    Springer
    Archives of microbiology 163 (1995), S. 352-356 
    Details
    ISSN: 1432-072X
    Keywords: Thiobacillus ferrooxidans ; Sulfide oxidation ; Sulfur colloids ; Bioleaching
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Thiobacillus ferrooxidans was cultivated on 100-nm-thick synthetic pyrite (FeS2) films. The steps of biooxidation were studied with high-resolution transmission electron microscopy. The crystallized sulfide was transformed into colloidal sulfur (4–70 nm, depending on the age of the cell and the degree of substrate oxidation; 70nm initially and 4nm after oxidation of the pyrite substrate), which was taken up and distributed over an organic capsule around the bacteria. This colloidal sulfur acted as intermediate energy storage and was transferred by contact to daughter cells not directly attached to the sulfide substrate.

    Morphology of bacterial leaching patterns by Thiobacillus ferrooxidans on synthetic pyrite (1988)
    Springer
    Archives of microbiology 149 (1988), S. 401-405 
    Details
    ISSN: 1432-072X
    Keywords: Thiobacillus ferrooxidans ; Pyrite oxidation ; Bacterial corrosion pits ; bacterial attachment ; Sulfide oxidation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Thiobacillus ferrooxidans has been cultivated on synthetic pyrite (FeS2) single crystals as the only energy source and the pyrite interface investigated with respect to characteristic morphological changes using scanning electron microscopy. Corrosion patterns of bacterial size were identified in different stages of development and correlated with bacterial activity. It appears that bacterial attack of the sulfide interface starts by secretion of organic substances around the contact area between the bacterial cell and the sulfide energy source. They might either be part of a “pseudo capsule” which shields the contact area or may form a sulfur absorbing and transporting organic film. Degradation of the sulfide occurs in the contact area below the bacterial cell leading to a corrosion pit which the bacterium may abandon after it has reached a depth of bacterial dimension. Electron spectroscopic (XPS) and X-ray fluorescence studies indicate a layer of organic substances covering the sulfide surface under bacterial leaching conditions, which is sufficiently thick for consideration in interfacial chemical mechanisms.
