Figure 3From: Absolute Quantification of Individual Biomass Concentrations in a Methanogenic CocultureqPCR calibration line of Methanospirillum hungatei JF1 in the presence of HS-DNA. The Ct values are plotted against the biomass concentration of Methanospirillum hungatei JF1. The horizontal axis is displayed on a logarithmic scale. Vertical error bars were obtained from qPCR triplicates.Back to article page
