Screening Identification and Probiotic Characterization of Konjac Glucomannan-Degrading Bacteria

To overcome the restricted bioactivity of konjac glucomannan (KGM) caused by its high molecular weight, KGM-degrading bacteria were isolated from konjac cultivation soil, diseased konjac tubers, and liquor fermentation systems. The probiotic potential of these strains was assessed based on acid and bile salt tolerance, resistance to simulated gastrointestinal fluids, and safety evaluations.
