Metabolism of Elements by Bacteria, Fungi, Algae, and Plants

  • Ei-Ichiro Ochiai
Part of the Biochemistry of the Elements book series (BOTE, volume 7)


From a structural standpoint, single-celled bacteria, algae, and fungi can all be regarded as being essentially the same. They have cell walls with cytoplasmic membrane underneath them. The cell walls are made of a variety of compounds, including cellulose, chitin, and peptidoglycans. The walls seem to have no specific physiological functions with regard to the absorption of inorganic (or, for that matter, organic) substances except in the case of the outer cell wall (or outer membrane) of gram-negative bacteria. The specific absorptions are instead carried out by the cytoplasmic membrane. The cell wall can, however, adsorb cationic metallic elements, since it is composed of compounds with negatively charged groups (e.g., phosphate, uronate) or, in certain organisms, containing coordinating groups.
