Figure 2From: Differential Gene Expression to Investigate the Effects of Low-level Electrochemical Currents on Bacillus subtilis Effects of DC and pre-treated media on planktonic cells of B. subtilis 168. Planktonic cells were sub-cultured to OD600 of 0.8, and 3 mL sub-culture was treated for 15 min at 37°C with no current, pre-treated medium, or applied current. CFUs were counted to determined cell viability after each treatment.Back to article page
