Abstract excerpt
Pseudomonas putida DLL-1 is a high effective methyl parathion (MP) degrading strain, which is also of chemotaxis to MP. cheA, responsible for coding histidine kinase, plays an important role in bacterial chemotaxis signal transduction. In order to study the effect of bacterial chemotaxis on in-situ biodegradation of pesticides, cheA in chromosome of P. putida DLL-1 was mutated by gene-targeting and successfully...
