Monounsaturated Fatty Acids Are Substrates for Aldehyde Generation in Tellurite-Exposed Escherichia coli

Figure 2

Fatty acid MUFA ratio profile (%) in E. coli BW25113 ΔyqhD exposed to the indicated toxicants. Fatty acids from E. coli BW25113 ΔyqhD carrying pBAD, pfabA, or pcfa plasmids were subjected to direct trans-esterification and analyzed by gas chromatography. Results are expressed as the percentage of total MUFA ratio in the membrane. Error bars represent SD (𝑛=5). Asterisks indicate a significant difference, 𝑃<0.05.
