Task: Question Generation
Input (English): The goals of this study were to determine if β-acid from hops (Humulus lupulus L.) could be used to control fructan fermentation by equine hindgut micro-organisms, and to verify the antimicrobial mode of action on Streptococcus bovis, which has been implicated in fructan fermentation, hindgut acidosis and pasture-associated laminitis (PAL) in the horse.', 'Suspensions of uncultivated equine faecal micro-organisms produced fermentation acids when inulin (model fructan) was the substrate, but β-acid (i.e. lupulone) concentrations ≥9\xa0ppm inhibited lactate production and mitigated the decrease in pH. Inulin-fermenting Strep.\xa0bovis was isolated from the β-acid-free suspensions after enrichment with inulin. The isolates were sensitive to β-acid, which decreased the viable number of streptococci in faecal suspensions, as well as growth, lactate production and the intracellular potassium of Strep.\xa0bovis in pure culture.
Output (English): Does inhibition of fructan-fermenting equine faecal bacteria and Streptococcus bovis by hop ( Humulus lupulus L. ) β-acid?
