“Permafrost samples only showed the existence of Methanocellales (Ganzert et al. 2007).” This sentence was incorrect. The clones estimated as Methanocellales belonged to an unknown methanogen group. The correct sentence is “Landfill samples only showed the existence of Methanocellales (Mori et al. 2003).”
Distribution maps of methanogenic archaeal clones isolated from other anaerobic environments. The principal component analysis was based on evolutionary distances of methanogenic archaeal 16S rDNA sequences (E. coli position, 358-690); the PC1 and PC2 components of the principal component analysis indicate first and second principal components, respectively. Their respective contributing percentages are between brackets. Grey triangles indicate the clones obtained from the paddy field ecosystems; Red circle, Methanobacteriales; green triangle, Methanomicrobiales; blue triangle, Methanosarcinales; dark blue circle, unknown methanogen
