Aims: Indri indri is a lemur of Madagascar which is critically endangered. The analysis of the microbial ecology of the intestine offers tools to improve conservation efforts. This study aimed to achieve a functional genomic analysis of three Lactiplantibacillus plantarum isolates from indris.
Methods And Results: Samples were obtained from 18 indri; 3 isolates of Lp. plantarum were obtained from two individuals. The three isolates were closely related to each other, with <10 single nucleotide polymorphisms, suggesting that the two individuals shared diet-associated microbes. The genomes of the three isolates were compared to 96 reference strains of Lp. plantarum. The three isolates of Lp. plantarum were not phenotypically resistant to antibiotics but shared all 17 genes related to antimicrobial resistance that are part of the core genome of Lp. plantarum. The genomes of the three indri isolates of Lp. plantarum also encoded for the 6 core genome genes coding for enzymes related to metabolism of hydroxybenzoic and hydroxycinnamic acids. The phenotype for metabolism of hydroxycinnamic acids by indri isolates of Lp. plantarum matched the genotype.
Conclusions: Multiple antimicrobial resistance genes and gene coding for metabolism of phenolic compounds were identified in the genomes of the indri isolates, suggesting that Lp. plantarum maintains antimicrobial resistance in defense of antimicrobial plant secondary pathogens and that their metabolism by intestinal bacteria aids digestion of plant material by primate hosts.

This study utilizes deep eutectic solvent (DES)-assisted enhancement of cellulose-based immobilized probiotics for efficient biotransformation of isofraxidin from Acanthopanax senticosus. Among seven probiotic strains tested, Lactiplantibacillus plantarum CICC 20767 exhibited the best catalytic activity. We explored the effects of 12 different DESs with varying hydrogen bond donors on the conversion capacity of the immobilized probiotics, with the highest efficiency observed using ChCl/EG (4.

This study investigated the survival dynamics of BG24, a probiotic strain, within reconstituted skim milk (RSM) and yeast extract (YE) matrices during the spray-drying (SD) process, encompassing of inlet/outlet air temperatures. Notably, optimum SD parameters were found to be an inlet air temperature of 150°C and outlet air temperature of 83°C, that achieving high viability (92.23%), and reducing both moisture content (MC) (3.

The process of biofilm formation during table olive fermentation is crucial to turning this fermented vegetable into a probiotic food. Some phenolic compounds have been described as important quorum-sensing molecules during biofilm development. The present in vitro study examined the effects of three phenolic compounds widely found in table olive fermentations (Oleuropein 0-3000 ppm, Hydroxytyrosol 0-3000 ppm, and Tyrosol 0-300 ppm) on the development of single biofilm by diverse microorganisms isolated from table olives ( 13B4, Lp119, and LPG1; Lp15 and LAB23; and yeasts Y12, Y13, and Y18).

Trichinellosis, a zoonotic disease transmitted through food and caused by , is a significant health concern worldwide. Therefore, developing a safe and effective vaccine to combat infection is essential. In this study, a nonantibiotic strain lacking the gene served as a live bacterial vector to deliver antigens to the host, creating a novel oral vaccine.

Daidzin, as one of isoflavone glycosides, has been reported to have multiple activities with few absorbed into body. However, the metabolic behavior of daidzin by intestinal flora has not been researched, that this defect severely constrains its applications. In this study, daidzin and its metabolites were qualitatively and quantitatively analyzed by HPLC and ultra-high performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) in the fermentation system for daidzin and fecal bacteria.
