Fig. 7From: Presence does not imply activity: DNA and RNA patterns differ in response to salt perturbation in anaerobic digestionComparison of RNA and DNA relative abundances of the selected 79 phylotypes in each of the samples (excluding the feed sludge sample). These 79 phylotypes had a relative abundance >0.1% in at least one sample and were present in all samples. The two most abundant methanogens [Methanosaeta, Phy1 (red) and an unclassified Methanomicrobiales phylotype, Phy54 (blue)] were highlighted, and the intensity of the colour relates to the salt concentration. The dashed line represents a DNA:RNA relative abundance ratio of 1Back to article page
