Electron microscopic analyses of ferromanganese concretions from the deep-sea have revealed in them a myriad of surface and internal structures, some of which have been identified or interpreted as being of microbiological origin (Dugolinsky et al., 1977; Greenslate, 1974; Harada and Nishida, 1976; LaRock and Ehrlich, 1975; Wendt, 1974; Xavier, 1976). These results, along with work showing the presence of manganese-oxidizing bacteria (Ehrlich, 1975; Nealson, 1978; Schütt and Ottow, 1978), indicate that microorganisms may greatly influence the growth of deep-sea concretions.
