Staphylococcus aureus RN6390 presents a diauxic growth in milk, due to amino acid limitation. Inactivation of the oligopeptide permease Opp3 (dedicated to the nitrogen nutrition of the strain) not only affects the growth of the strain but also results in reduced expression levels of three major extracellular proteases.
由于氨基酸限制,金黄色葡萄球菌RN6390在牛奶中呈现双相生长。寡肽通透酶Opp3(专门负责该菌株的氮营养)的失活不仅影响该菌株的生长,还导致三种主要细胞外蛋白酶的表达水平降低。
