In order to study the `in vitro' fixation of metal ion species on algal and bacterial sedimentary organic matter, two algal mat samples have been studied. The main interest of this organic matter is its specific cyanobacterial origin. After isolation and purification, the organic matter was characterized by elemental and functional analysis, infrared spectroscopy. carbohydrates and amino-acid titration. These analyses indicate the richness of this type of organic matter in amino acids and carbohydrates, its poverty in aromatic structures, and to ascertain the types of bacteriological and chemical transformations undergone by the original biological compounds in the first steps of the diagenesis.
