Figure 4From: Differential Gene Expression to Investigate the Effects of Low-level Electrochemical Currents on Bacillus subtilis Effects of DC and pre-treated media on biofilms of B. subtilis 1500. Biofilms grown for 2 days on 304L stainless steel electrodes at 37°C were treated with pre-treated LB medium or total applied current for 15 min as indicated. Cell density of the biofilms was calculated from the CFU data.Back to article page
