The influence of cultivation conditions on the growth and pigmentation of S. marcescens was studied. The cultures under study grew in media containing glycerin, glucose or acetate and organic or mineral nitrogen. Pigment formation occurred in a medium with organic nitrogen and glycerin or acetate, but not glucose. Sodium chloride inhibited the growth of cultures, but at a concentration not exceeding 4-5% increased the accumulation of prodigiosin. Prodigiosin was accumulation by the culture growing at 28 degrees C, while at 37 degrees C no accumulation of the pigment occurred. The illumination of the growing culture with visible light decreased the intensity of its pigmentation. Prodigiosin apparently plays an important role in the metabolism of S. marcescens and is linked with the energy exchange of the cell.
研究了培养条件对粘质沙雷氏菌生长和色素沉着的影响。所研究的培养物在含有甘油、葡萄糖或乙酸盐以及有机或无机氮的培养基中生长。色素形成发生在含有有机氮和甘油或乙酸盐的培养基中，但在含有葡萄糖的培养基中不发生。氯化钠抑制培养物的生长，但在浓度不超过4 - 5%时会增加灵菌红素的积累。灵菌红素是由在28℃下生长的培养物积累的，而在37℃时不发生色素积累。用可见光照射生长中的培养物会降低其色素沉着强度。灵菌红素显然在粘质沙雷氏菌的代谢中起重要作用，并与细胞的能量交换有关。
