The 57 conjugative Cit plasmids isolated from 72 citrate-utilizing (Cit+) Escherichia coli strains from various sources were classified into four groups on the basis of their genetic properties. Escherichia coli K13 strains carrying these Cit plasmids could utilize cis-aconitate or tricarballylate, in addition to citrate.
从72株来自不同来源的利用柠檬酸盐（Cit+）的大肠杆菌菌株中分离出的57个接合型Cit质粒，根据其遗传特性被分为四组。携带这些Cit质粒的大肠杆菌K13菌株除了能利用柠檬酸盐外，还能利用顺乌头酸或三羧甲基丙烷。
