a
Control, control group (LPS-free anaerobic water); R-LPS, regular LPS (200,000 EU) as a carbon source; GLU, glucose as a carbon source; GLU + R-LPS, glucose plus R-LPS (200,000 EU). Lactate concentrations are millimolar.
b
Results were obtained after adding glucose. —, not applicable (no growth).
c
—, data not shown.
