    • A temperature-sensitive plasmid which is capable of autonomous replication in Escherichia coli K-12 at 10–30° C., but, at a temperature of 33° C. or more, is incapable of autonomous replication in Escherichia coli K-12 or is distributed unhomogeneously upon the cell division of Escherichia coli K-12, thereby not to be stably carried within cells of Escherichia coli K-12 under said temperature, and which is incapable of autonomous replication in a microorganism belonging to the genus Escherichia other than Escherichia coli K-12 or is distributed unhomogeneously upon cell division of said microorganism at any temperature, thereby not to be stably carried within cells of said microorganism.
    • 能够在10-30℃,但在33℃或更高温度下能够在大肠杆菌K-12中自主复制的温度敏感性质粒不能在大肠杆菌K-12或 在大肠杆菌K-12的细胞分裂时不均匀地分布,因此在所述温度下不能稳定地携带在大肠杆菌K-12的细胞内,并且不能在属于埃希氏杆菌属的大肠杆菌属的微生物中自主复制 大肠杆菌K-12或在任何温度下细胞分裂细胞时分布不均匀,从而不能在所述微生物的细胞内稳定携带。
