中文摘要：

Pseudomonas putida ND6是一个高效降解萘的菌株,含有101 858 bp的萘降解质粒pND6-1.用实时定量PCR方法测定了Pseudomonas putida ND6菌株中pND6-1的拷贝数为2.这是第一个测定分子大小超过100 kb的细菌大质粒拷贝数的报道.

英文摘要：

Pseudomonas putida ND6 is a highly efficient naphthalene-degrading strain, which contains the 101 858 bp naphthalene-degrading plasmid pND6-1.The copy number of pND6-1 in Pseudomonas putida ND6 is two determined by quantitative real-time PCR.This is the first report of copy number of plasmid that the size is more than 100 kb.
