Electron microscopy of Gallionella ferruginea.
For over 80 years prior to the work of Cholodny (1924, 1926) the twisted ribbons of ferric hydroxide found in iron-bearing waters were described as living organisms of the genera Gallionella and Spirophyllum. These early observations have been conveniently summarized and evaluated by Pringsheim (1949), so that at the present time Spirophyllum may be considered synonymous with Gallionella. It re...
متن کاملSilicon and phosphorus linkage with iron via oxygen in the amorphous matrix of Gallionella ferruginea stalks.
Bacterial species belonging to the genus Gallionella are Fe-oxidizing bacteria that produce uniquely twisted extracellular stalks consisting of iron-oxide-encrusted inorganic/organic fibers in aquatic environments. This paper describes the degree of crystallinity of Gallionella stalks and the chemical linkages of constituent elements in the stalk fibers. Transmission electron microscopy reveale...
متن کاملTwo Types of Morphologically Distinct Fibers Comprising Gallionella ferruginea Twisted Stalks
Two morphologically distinct extracellular stalk fibers produced by Gallionella ferruginea were compared by electron microscopy and elemental analysis. The thick- and fine-fiber stalks were different in structure on a micrometer scale and in the site on the mother cell to which they were attached, but on a nanometer scale they were similar in ultrastructure and in the elemental composition of t...
متن کاملNanometer-scale visualization and structural analysis of the inorganic/organic hybrid structure of Gallionella ferruginea twisted stalks.
The so-called Fe/Mn-oxidizing bacteria have long been recognized for their potential to form extracellular iron hydroxide or manganese oxide structures in aquatic environments. Bacterial species belonging to the genus Gallionella, one type of such bacteria, oxidize iron and produce uniquely twisted extracellular stalks consisting of iron oxide-encrusted inorganic/organic fibers. This paper desc...
