Probiotic Potential and Cholesterol-Lowering Capabilities of Bacterial Strains Isolated from Pericarpium Citri Reticulatae ‘Chachiensis’

Since abundant and various bacteria OTU including Bacillus have been identified in PCR-Chachiensis through culture-independent methods, we further investigated the probiotic potential of the culturable bacterial strains in PCR-Chachiensis

  • Accepted: 1 June 2021Pericarpium Citri Reticulatae is the dried and aged pericarps of Citrus reticulata Blanco and its cultivars
  • Since abundant and various bacteria OTU including Bacillus have been identified in PCR-Chachiensis through culture-independent methods, we further investigated the probiotic potential of the culturable bacterial strains in PCR-Chachiensis
  • Lactobacillus and Paenibacillus were confirmed, which might open up new opportunities for probiotics
  • Several strains from genus Lactobacillus and Paenibacillus were confirmed, which might open up5 ofnew opportunities for probiotics
  • The highest co-aggregation with S. paratyphi and E. coli was found in N17-12, together with its significant antibacterial activity against these two pathogens, B. megaterium N17-12 was suggested as a good probiotic candidate from the point of view of the antibacterial potential
  • Our results indicated that eight isolates showed great survival in the simulated GIT stressful conditions, with nonhemolytic and no biogenic amine formation
  • Further in vitro and in vivo analysis should be performed so that these isolates could be used for human or animal and food or feed applications
