Restoration of Nitrate Respiration in Pseudomonas aeruginosa under Growth Limitations.

Abstract excerpt

Gene mutations are a fundamental survival strategy in bacteria and often accompany cell growth. We herein demonstrate that Pseudomonas aeruginosa recovered growth under anoxic conditions through a mutation in an essential regulatory gene required for nitrate respiration, overcoming initial growth limitations. Although the open-ocean isolate P. aeruginosa Ocean-1187 possesses denitrification-related genes, it was...
