Fig. 1From: Evaluation of native potential probiotic bacteria using an in vitro ruminal fermentation systemAccumulated gas volume per gram of incubated substrate over time in fermenters which used wheat straw as substrate. Filled triangle, filled circle, open triangle Fermentation systems to which strains 21C, 22C and 62C, respectively, had been added. Filled square Control fermentation system, which differed from experimental systems only by the absence of ruminal strainsBack to article page
