The effect of NaCl in culture medium was studied on the properties of cell wall of Tetracoccus soyae. The results indicated that Nacl in culture medium influenced the properties of the teichoic acid part of the cell wall but not the peptidoglycan part.Of cell wall components, glucosamine incresed, and hexose decreased with increasing NaCl concentration in the culture medium, while the contents of phosphoric acid and uronic acid were not affected.The composition of teichoic acid was determined as ribitol, alanine, glucose, glucosamine and phosphoric acid. With increasing NaCl concentration in the culture medium, the amount of alanine decreased and that of glucosamine increased.The effect of NaCl in the culture medium on the Mg^<2+>-binding ability of Tetracoccus soyae's cell (or cell wall) was investigated. The Mg^<2+>-binding ability of cell (or cell wall) grown in the presence of NaCl was higher than that of the cell (or cell wall) grown in the absence of NaCl. The Mg^<2+>-binding site in Tetracoccus soyae's appeared to be located in the teichoic acid part of the cell wall.
