FIG. 3.

Compositions of rRNA gene libraries obtained from shower curtain samples. Numbers of clones of each rRNA gene sequence from libraries are grouped as identified on the pie charts as follows: Methylobact, Methylobacterium spp.; Sphingom, Sphingomonas spp.; α-Protbact, α-proteobacteria; δ-Protbact, δ-proteobacteria; γ-Protbact, γ-proteobacteria; Actinomy, Actinomycetales; hGCgpbact, high-G+C gram-positive bacteria; CFBgroup, Cytophaga-Flavobacteria-Bacteroides group; Sphingobac, sphingobacteria.
