Figure 4

The overall Archaea community structure, relative abundance and clustering of palm oil mill effluents (POME) from Côte d’Ivoire. (A) PCoA using Bray–Curtis dissimilarity based on the genus-level ASV shows significant differences between samples (q = 0.014, F = 0.009, PERMANOVA). (B) Relative abundance (%) of predominant bacteria at phylum level. (C) The hierarchically heat map clustered with top 20 archaea genera between the positive samples. The abundance difference is shown as a color key with a blue colour gradient. The ASV relative abundance data were normalized [log10 (xi + 1)-transformed] before generating the heat map using R version 3.6.3 software (https://cran.r-project.org/bin/windows/base/old/3.6.3/).
