Filter paper strips containing a pigment precursor extracted from Serratia marcescens strain 933 were used to determine whether white, clinical S. marcescens strains could form pigment syntrophically. In all, 114 strains (113 of clinical origin) were tested, and 99% were found to develop colors ranging from violets to pinks.
含有从粘质沙雷氏菌933菌株中提取的色素前体的滤纸条被用于确定白色的临床粘质沙雷氏菌菌株是否能通过协同作用形成色素。总共测试了114株菌株(113株来自临床),发现99%的菌株能产生从紫色到粉色的颜色变化。
