Growth analysis of B. fragilis trx and oxyR mutant strains in anaerobic and oxidized media. Strains were grown overnight in BHIS and then inoculated into either fully oxidized medium (Ox) or anaerobic medium (An). Growth was measured on a spectrophotometer at 550 nm. The results shown are the averages from triplicate observations in two growth experiments. Strains IB101 (wild type, ⧫), IB298 (ΔoxyR, ⋄), IB498 (ΔtrxC ΔtrxE ΔtrxF ΔtrxG ▪), IB499 (ΔtrxC ΔtrxE ΔtrxF ΔtrxG ΔoxyR::tetQ □), IB483 (ΔtrxC ΔtrxD::cfxA ΔtrxE ΔtrxF ΔtrxG ▴), and IB500 (ΔtrxC ΔtrxD::cfxA ΔtrxE ΔtrxF ΔtrxG ΔoxyR::tetQ ▵) were used.
