Fig. 2

Phylogenetic tree of bacterial community (a) and fungal community (b) present in the hemp fibre samples. The numbers in the figures show the bootstrap values between the branches. In a α-, ß-, and γ-proteobacteria have blue, brown and purple braches, respectively, while Bacteroidetes have green branches. In b Ascomycota and Basidiomycota fungi have brown and blue branches, respectively. Relative abundance is shown in % calculated based on the number of bacterial (a) and fungal (b) clones at each retting time. Samples are sorted according to retting time (0 days = blue; 7 days = green; 14 days = yellow; 20 days = orange)
