S-(2-Aminoethyl)L-cysteine (AEC) at 2 X 10(-1) mM concentration completely inhibited the growth of Bacillus subtilis. This inhibitory effect was readily reversed by 2 X 10(-2) mM L-lysine. Besides L-lysine, L-aspartic acid was only effective of all the natural amino acids tested in reversing the AEC-mediated growth inhibition. AEC resistant mutants of B. subtilis were isolated and found to excrete L-lysine in high yields.
2×10⁻¹ mM浓度的S-(2-氨基乙基)-L-半胱氨酸（AEC）完全抑制枯草芽孢杆菌的生长。2×10⁻² mM的L-赖氨酸能轻易逆转这种抑制作用。除L-赖氨酸外，在所有测试的天然氨基酸中，只有L-天冬氨酸能有效逆转AEC介导的生长抑制。分离出枯草芽孢杆菌的AEC抗性突变体，发现其能高产分泌L-赖氨酸。
