Abstract

The resting cells of S. aureus strain Smith (diffuse) lost marked amount of free amino acids and proteins during their starvation. The starved cells contained less coagulase and that enzyme was released into the medium during starvation. After transfer into nutrient medium, those cells produced less coagulase than the non-starved ones. The restoration of amino acid pool resulted in coagulase production on initial level.

摘要

金黄色葡萄球菌史密斯菌株（扩散型）的静息细胞在饥饿期间损失了大量游离氨基酸和蛋白质。饥饿细胞中凝固酶含量较少，且该酶在饥饿期间释放到培养基中。转移到营养培养基后，这些细胞产生的凝固酶比未饥饿的细胞少。氨基酸库的恢复导致凝固酶产量恢复到初始水平。
