Figure 2. — Comparison of H₂-facilitated anaerobic growth of S. Typhimurium strains. Anaerobic WT/JSG210 (represented as circles), RLK7/ΔhycC (represented as diamonds) and RLK6/ΔgudT (represented as triangles) in minimal medium with 0.4% d-glucarate. Solid lines indicate growth with added H₂ (20% v/v) and dashed lines indicate growth without added H₂. The standard deviation was less than 4% of the mean in every case, so that the added H₂ condition is significantly greater than without H₂ for each individual strain for all points at 4 h and greater at p ≤ 0.05 by Student's t-test. Without H₂, there was also a significant difference in JSG210 and the RLK7 mutant at 6 and 8 h points (p ≤ 0.05 by Student's t-test), while with H₂, the WT was significantly greater than strain RLK6 only.
