The chlorinated aromatic acids 3-chlorobenzoate and 4-chlorobenzoate are chemoattractants for Pseudomonas putida PRS2000. These compounds are detected by a chromosomally encoded chemotactic response to benzoate which is inducible by beta-ketoadipate, an intermediate of benzoate catabolism. Plasmid pAC27, encoding enzymes for 3-chlorobenzoate degradation, does not appear to carry genes for chemotaxis toward chlorinated compounds.
氯化芳香酸3-氯苯甲酸酯和4-氯苯甲酸酯是恶臭假单胞菌PRS2000的趋化剂。这些化合物通过对苯甲酸酯的染色体编码趋化反应来检测,该反应可被β-酮己二酸(苯甲酸酯分解代谢的中间产物)诱导。编码3-氯苯甲酸酯降解酶的质粒pAC27似乎不携带对氯化化合物的趋化性基因。
