Quantification of Archaea . Confocal images were collected from triplicate samples from the aeration tank, reject water and the digester. A threshold of 100 was applied to remove noise and Archaea and Bacteria was quantified as the area positive for ARC915 or MX825 (but not EUB) and EUB (but not ARC915 or MX825), respectively. The given values are average percentages of Archaea of the total area with values from 90 confocal images. The standard deviations are given as error bars.
