Influence of NO and NO synthase (NOS) on the swarm rate of B. subtilis 3610. Swarm expansion assays with strain 3610 wild-type (white bars) and strain 3610Δnos (gray bars) were performed on 0.7% LB agar without supplementation (controls) or supplemented with 100 μM L-NAME (NOS inhibitor), 100 μM c-PTIO (NO scavenger) and 20 μM or 200 μM Noc-18 (NO donor). Error bars indicate standard deviation (N = 6). Differences between individual dataset are not statistically significant (α = 0.01; see Material and Methods section for details).
