| Outline of Final Research Achievements |
We discovered Rhodococcus sp. 065240, which degrades the benzotrifluoride through defluorination. As a result of molecular biological analysis, it was found that this strain possesses btf gene cluster, which is similar to isopropyl benzene degradation cluster. Those genes were related to benzotrifluoride defluorination that suggested by experiments of btf genes deletion mutant. Confirmation of using heterologous btf gnen expression in Corynebacterium glutamicum found that oxidation reaction of benzotrifluoride which catalyzed by BtfA and BtfB, produced trifluoromethyl catechol. Then, basic condition of culture seems to lead spontaneous defluorination of catechol compound. Therefore, it was suggested that applying btfC gene under acidic condition with btfAB not only suppresses defluorination but also transforms benzotrifluoride to new fluorometabolite.
