Abstract
Colitis in equines has high morbidity and mortality rates, which severely affects the development of the equine-breeding industry. With the issuance of antibiotic bans, there is an urgent need for healthier and more effective alternatives. In recent years, probiotics have been widely used as microbial feed additives in animal husbandry, playing a crucial role in preventing and treating diarrhea and regulating host immune function. In this study, we isolated and screened a strain with rapid and stable acid production using bromocresol purple, litmus milk coloration tests, and acid production performance assessments. Based on morphological characteristics, physiological and biochemical properties, and 16S rDNA identification, the strain was identified as Pediococcus pentosaceus and named M6. The Pediococcus pentosaceus M6 exhibited stable growth and tolerance to high temperatures, acid and bile salt concentrations, and simulated gastrointestinal fluid environments. The M6 strain demonstrated good antibacterial effects against Escherichia coli, Staphylococcus aureus, and Salmonella. The M6 strain did not produce hemolysis zones on Columbia blood agar plates, indicating its high safety, and was found to be insensitive to 12 antibiotics, including cephalexin and neomycin. Additionally, intervention in mice with dextran sulfate sodium (DSS)-induced colitis alleviated weight loss and shortened colon length. To a certain extent, it regulated the expression of inflammatory cytokines and the gut microbiota within the body and reduced inflammatory cell infiltration and intestinal barrier damage. In summary, the isolated Pediococcus pentosaceus M6 strain exhibited excellent probiotic properties and could alleviate DSS-induced colitis in mice, suggesting its potential application value as a probiotic in animal husbandry.

Evaluation of the Safety and Impact of Heat-Treated Lactiplantibacillus plantarum KM2 Fermentation on Gut Microbiome Architecture. J Microbiol Biotechnol 2024; 35:e2411069. [PMID: 39757420 PMCID: PMC11813362 DOI: 10.4014/jmb.2411.11069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2024] [Revised: 12/16/2024] [Accepted: 12/17/2024] [Indexed: 01/07/2025]
Abstract
Postbiotics, bioactive compounds from the fermentation process by probiotics, are gaining attention for their potential health benefits as safer alternatives to live probiotic microbes. Lactiplantibacillus plantarum is a well-studied probiotic species known for promoting gut health and immune modulation. However, the safety and effects of its postbiotic formulations on the gut microbiome structure remain less explored. This study presents a randomized, double-blind, placebo-controlled human study of KLP-KM2, a postbiotic consisting of heat-treated L. plantarum KM2 fermentation complex, in elderly participants. Over 12 weeks, KLP-KM2 consumption did not result in noticeable adverse reaction cases compared to the placebo. Nevertheless, the gut microbial diversity and taxonomic architecture of the KLP-KM2 recipients were differentiated from those of the placebo recipients after 12 weeks. A notable outcome was the increase in the number of subjects carrying Veillonella spp., which contributed to the distinct gut microbiome profiles observed between the two groups. Interestingly, KLP-KM2 facilitated the de novo colonization of Veillonella spp. in subjects who had not harbored these bacteria at the baseline. These results suggest the potential of KLP-KM2 as a safe and effective postbiotic intervention to enhance energy metabolism and mobility in older adults.
