Prodigiosin biosynthesis in Serratia marcescens depends on growth conditions. In the presence of various concentrations of NaCl, pigment synthesis started later, but up to 4-5% NaCl increased prodigiosin accumulation per biomass unit. Visible light (< 2,000 lux) influenced pigmentation without changing the growth characteristics of the culture. The maximum prodigiosin content in dark and light cultures was observed on days 3-4 and 2-3, respectively. The influence of illumination conditions on pigmentation of S. marcescens was demonstrated. Light directly affects the pigment itself which is synthesized by the culture. Growing cells contain mono and dimer forms of prodigiosin in glycerol, with light influencing these pigments.
粘质沙雷氏菌中灵菌红素的生物合成取决于生长条件。在存在不同浓度氯化钠的情况下，色素合成开始较晚，但高达4 - 5%的氯化钠可增加每生物量单位的灵菌红素积累量。可见光（< 2000勒克斯）影响色素沉着，但不改变培养物的生长特性。黑暗和光照培养物中灵菌红素的最大含量分别在第3 - 4天和第2 - 3天观察到。光照条件对粘质沙雷氏菌色素沉着的影响得到了证实。光直接影响培养物合成的色素本身。生长中的细胞在甘油中含有灵菌红素的单体和二聚体形式，光会影响这些色素。
