摘要：
The morphology ofGallionella ferruginea and other microorganisms in the ochreous precipitates in acid mine drainage (AMD) were investigated using a scanning electron microscope (SEM) equipped with energy dispersive spectrometry (EDS). Mineralogy of the precipitate containing the microorganism was characterized by X-ray diffraction analysis. TheGallionella ferruginea having twisted structure are found from precipitate samples on the stream bottom in AMD. Other microorganisms, characterized by coccus, bacillus, rod or cylindrical forms, are also observed in the precipitates. The ochreous preciptate was appeared reddish brown color (Munsell color 3.5YR hues) and consisted mainly of ferrihydrite with minor geothite.
