Community and Proteomic Analysis of Anaerobic Consortia Converting Tetramethylammonium to Methane

Figure 4

(a) 16S rRNA gene copies (on average) of archaeal and bacterial populations and (b) the estimated ratios of archaeal to bacterial populations in methanogenic sludge from tetramethylammonium-degrading CMSS (sample CMJP) and UASB reactors (samples UASB1a-UASB5a). Coefficients of variance (CV) for archaeal and bacterial Q-PCR experiments (triplicate analysis per sample) are 1.4~35.1% and 2.3~12.8%, respectively.
