Taxa in abundance greater than 1% are bolded. Taxa were ranked according to their overall abundance in the 16S rRNA amplicons for the samples. Data are for field samples (water) and the communities growing on steel coupons (biofilm) in incubations of field samples in medium with bicarbonate, but without sulfate. Only taxa with an average abundance in excess of 0.25% are shown.
