FIG. 1.

Percent resistance of cultivable aerobic and anaerobic epibiotic bacterial communities to Na₂SeO₃ (1,000 μg/ml), K₂TeO₃ (300 μg/ml), K₂TeO₄ (300 μg/ml), NaVO₃ (900 μg/ml), and Na₃VO₄ (1,000 μg/ml). Samples were from sulfide worms (A) and tubeworms (B). All populations were normalized to the highest CFU value measured for each animal and oxygenation treatment, which was assumed to represent 100% of the bacterial population under those conditions. Values provided are the means calculated from three samples each.
