STUDIES ON MUTANTS OF BACILLUS SUBTILIS REQUIRING D-GLUTAMIC ACID

[摘要] When mutant 3d is incubated in a medium devoid of D-glutamic acid, the number of viable cells increases for a while and after the lapse of seven hours begins to decrease abruptly. Because D-glutamic acid is a major component of cell wall and a minor component of cytoplasm, and because the strain cannot synthesize D-glutamic acid although it can synthesize L-glutamic acid and other L-amino acids, it is concluded that the phenomenon mentioned above is caused by the unbalanced synthesis between cell wall and cytoplasm.
