^‡ n=10.

^a,b = groups not connected by the same letter are significantly different within Set A (p < 0.01). Each bacterial subset considered independently.

^c,d = groups not connected by the same letter are significantly different within Set B (p < 0.01). Each bacterial subset considered independently.
