Abstract

The benefits of supplementing livestock diets with extracts from Yucca schidigera have been attributed to inhibition of selected gut microbes. The antimicrobial constituents were identified as three butanol-extractable 5 beta-spirostan-3 beta-ol saponins using Bacillus pasteuriiand Saccharomyces cerevisiae as test prokaryotic and eukaryotic organisms, respectively. Although these saponins inhibited microbial growthat low cell densities, their impact was associated with adsorption tothe microbes and they had no effect on dense microbial populations. The antimicrobial saponins were also observed to adsorb to the microbiota and other solids of the porcine cecum. The implications for gut microbes differ according to their ecological niche: Those sequestered tofeed particles or the gut lining may accumulate saponins, whereas those flushed out synchronously with the digesta should be protected by high population densities.
