| 1.14.12.11 | more |
introduction of a plasmid containing the entire tod operon todC1C2BADE to Pseudomonas putida T57 to enhance its ability to degrade 4-chloroaniline. The resulting strain shows 250-fold higher 4-chloroaniline degradation activity the parental strain. The recobinant strain degrades 2-chloroaniline, 3-chloroaniline, and 3,4-dichloroaniline as well as 3-chloroaniline, but not 3,5-dichloroaniline |
