Abstract: | The bacteria studied released into the medium ten to eleven organic acids. Soil organisms excreted mainly pyruvic and alpha-ketoglutaric acids, while strains from the root zone--gluconic acid and unidentified uronic acid (y2). Mean indices of total production of the organic acids by bacteria were in the following order: rhizosphere less than soil less than mycorrizosphere. Bacteria from the root zone released into the medium very large amounts of pyruvic, gluconic, and uronic (y2) acids--in some instances several times higher than bacterial dry mass. |
