Analysis of a Methanogen and an Actinobacterium Dominating the Thermophilic Microbial Community of an Electromethanogenic Biocathode

Figure 5

Heatmap and hierarchical clustering of the differentially expressed genes of the Coriobacteriaceae sp. strain EMTCatB1. The scale of the heatmaps was the average of the TMM-normalized count values transformed so that the mean was 0 and the standard deviation was 1 (-score). The assigned clusters were indicated at the rightmost column, with the number of genes contained in each cluster shown in brackets. The blue arrowheads indicate the genes potentially involved in cathodic electron consumption. The red arrowheads indicate the stress-related genes.
