Biphenyl Modulates the Expression and Function of Respiratory Oxidases in the Polychlorinated-Biphenyls Degrader Pseudomonas pseudoalcaligenes KF707.

ABSTRACT: Pseudomonas pseudoalcaligenes KF707 is a soil bacterium which is known for its capacity to aerobically degrade harmful organic compounds such as polychlorinated biphenyls (PCBs) using biphenyl as co-metabolite. Here we provide the first genetic and functional analysis of the KF707 respiratory terminal oxidases in cells grown with two different carbon sources: glucose and biphenyl. We identified five terminal oxidases in KF707: two c(c)aa₃ type oxidases (Caa₃ and Ccaa₃), two cbb₃ type oxidases (Cbb₃1 and Cbb₃2), and one bd type cyanide-insensitive quinol oxidase (CIO). While the activity and expression of both Cbb₃1 and Cbb₃2 oxidases was prevalent in glucose grown cells as co
