The Effect of Saturated Fatty Acids on Methanogenesis and Cell Viability of Methanobrevibacter ruminantium

Figure 1

Methane production rate (μmol/mg cell DM/min) in cell suspensions of M. ruminantium in K⁺-containing buffer (𝑛=3) in response to supplementation of different concentrations of lauric acid (A), myristic acid (B), palmitic acid (C), and stearic acid (D) at 37°C and of stearic acid at 50°C (E) (Experiment  1). Means within time point with unequal letters (a, b) are different at 𝑃<0.05. Bars represent standard errors.
