The production of type 5 capsular polysaccharide by Staphylococcus aureus in synthetic media was investigated. The influence of medium components on capsular polysaccharide synthesis appeared to relate to the presence or absence of the component rather than to concentration gradient. The production of type 5 capsular polysaccharide was linked to energy availability and energy source, but not to carbohydrate concentration or carbon/nitrogen ratio. Regulation of capsular polysaccharide production by S. aureus in response to medium changes would appear to differ from that typically displayed in other organisms that produce polysaccharides.
研究了金黄色葡萄球菌在合成培养基中5型荚膜多糖的产生情况。培养基成分对荚膜多糖合成的影响似乎与该成分的存在与否有关，而非与浓度梯度有关。5型荚膜多糖的产生与能量供应和能量来源有关，但与碳水化合物浓度或碳/氮比无关。金黄色葡萄球菌对培养基变化做出反应时，其荚膜多糖产生的调控似乎与其他产生多糖的生物体中典型表现的调控不同。
