Abstract
This study aims to explore novel lactic acid bacteria (LAB) from breast-fed infants' faeces towards characterizing their antimicrobial compound, bacteriocin. The LAB, Lacticaseibacillus paracasei F9-02 showed strong antimicrobial activity against clinical pathogens. Their proteinaceous nature was confirmed as the activity was completely abolished when treated with proteinaceous enzymes and retained during neutral pH and catalase treatment. The purified bacteriocin showed antimicrobial activity at the minimum inhibitory concentration (MIC) value of 7.56 μg/ml against vancomycin-resistant Enterococcus sp. [vancomycin-resistant enterococcal (VRE)], and methicillin-resistant Staphylococcus aureus (MRSA), 15.13 μg/ml against Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella enterica subsp. enterica serotype typhi and 30.25 μg/ml against Shigella flexneri. Present study also proved the bactericidal, non-cytotoxic and non-hemolytic nature of bacteriocin. Additionally, bacteriocin retained their stability under various physico-chemical conditions, broad range of pH (2-10), temperature (40-121°C), enzymes (amylase, lipase and lysozyme), surfactants [Tween-20, 80, 100 and sodium dodecyl sulfate (SDS)], metal ions (CaCl2 , FeSO4 , ZnSO4 , MgSO4 , MnSO4 , CuCl2 ) and NaCl (2%-8%). The molecular weight of bacteriocin (~28 kDa) was determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), functional and active groups were assessed by Fourier Transform-Infrared (FT-IR). To our knowledge, this is the first study reporting L. paracasei from breast-fed infants' faeces and assessing their antimicrobial compound, bacteriocin. The study results furnish the essential features to confirm the therapeutic potential of L. paracasei F9-02 bacteriocin.

Ben-Miled H, Benoit-Biancamano MO, Ben-Mahrez K, Réjiba S. Alpha-amylase and alphaglucosidase inhibitory properties, beta-galactosidase activity, and probiotic potential of lactic acid bacteria and bifidobacteria from Apis mellifera intermissa and its products. World J Microbiol Biotechnol 2023; 39:205. [PMID: 37221413 DOI: 10.1007/s11274-023-03648-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 05/15/2023] [Indexed: 05/25/2023]
Abstract
The present study aimed to evaluate the probiotic potential, α-amylase and α-glucosidase inhibitory effects, and β-galactosidase production of 19 non haemolytic lactic acid bacteria and bifidobacteria previously identified and isolated from honey bee gastrointestinal tract (BGIT) of Apis mellifera intermissa, honey, propolis and bee bread. The isolates were screened according to their high resistance to lysozyme and potent antibacterial activity. Our results indicated that among the 19 isolates, Limosilactobacillus fermentum BGITE12.2, Lactiplantibacillus plantarum BGITEC13, Limosilactobacillus fermentum BGITEC5.1 and Bifidobacterium asteroides BGITOB8, isolated from BGIT exhibited a good tolerance to 100 mg/mL lysozyme (> 82%), excellent tolerance to 0.5% bile salt [survival rate (SR) ≥ 83.19% ± 0.01], and a high SR (≥ 80.0%) under gastrointestinal tract conditions. The auto-aggregation ability was high (auto-aggregation index ranging from 67.14 ± 0.16 to 92.8% ± 0.03) for L. fermentum BGITE12.2, L. plantarum BGITEC13, and B. asteroides BGITOB8, and moderate for L. fermentum BGITEC5.1 (39.08% ± 0.11). Overall, the four isolates showed moderate co-aggregation capacity with pathogenic bacteria. They exhibited from moderate to high hydrophobicity towards toluene and xylene. The safety assessment revealed that the four isolates lacked gelatinase and mucinolytic activities. Also, they were susceptible to ampicillin, clindamycin, erythromycin, and chloramphenicol. Interestingly, the four isolates showed α-glucosidase and α-amylase inhibitory activities ranging from 37.08 ± 0.12 to 57.57% ± 0.1 and from 68.30 ± 0.09 to 79.42% ± 0.09, respectively. Moreover, L. fermentum BGITE12.2, L. plantarum BGITEC13, L. fermentum BGITEC5.1 isolates exhibited β-galactosidase activity over a wide range of 52.49 ± 0.24-746.54 ± 0.25 Miller Units. In conclusion, our findings suggest that the four isolates could be potential candidates for probiotics with interesting functional properties.

Probiotics, their action modality and the use of multi-omics in metamorphosis of commensal microbiota into target-based probiotics. Front Nutr 2022; 9:959941. [PMID: 36185680 PMCID: PMC9523698 DOI: 10.3389/fnut.2022.959941] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 08/24/2022] [Indexed: 11/13/2022] Open
Abstract
This review article addresses the strategic formulation of human probiotics and allows the reader to walk along the journey that metamorphoses commensal microbiota into target-based probiotics. It recapitulates what are probiotics, their history, and the main mechanisms through which probiotics exert beneficial effects on the host. It articulates how a given probiotic preparation could not be all-encompassing and how each probiotic strain has its unique repertoire of functional genes. It answers what criteria should be met to formulate probiotics intended for human use, and why certain probiotics meet ill-fate in pre-clinical and clinical trials? It communicates the reasons that taint the reputation of probiotics and cause discord between the industry, medical and scientific communities. It revisits the notion of host-adapted strains carrying niche-specific genetic modifications. Lastly, this paper emphasizes the strategic development of target-based probiotics using host-adapted microbial isolates with known molecular effectors that would serve as better candidates for bioprophylactic and biotherapeutic interventions in disease-susceptible individuals.
