The aim of this study was to investigate the impact of the prebiotic Galacto-oligosaccharide (GOS) on the growth of probiotics L. plantarum 14,917 and its effect on the inhibitory ability of L. plantarum 14,917 against the growth of Streptococcus mutans and Candida albicans in an in vitro model. Single-species growth screenings were conducted in TSBYE broth with 1% glucose and 1\u20135% GOS. Interaction experiments were performed using duo- and multi-species models with inoculation of 105 CFU\/mL S. mutans, 103 CFU\/mL C. albicans, and 108 CFU\/mL L. plantarum 14,917 under 1%, 5% GOS or 1% glucose. Viable cells and pH changes were measured. Real-time PCR was utilized to assess expression of C. albicans and S. mutans virulence genes. Six replicates were used for each group. Student\u2019s t-test, one-way ANOVA, and Kruskal-Wallis were employed to compare the outcomes of different groups. GOS significantly inhibited the growth of C. albicans and S. mutans in terms of growth quantity and speed when the two strains were grown individually. However, GOS did not affect the growth of L. plantarum 14,917. Moreover, 1% and 5% GOS enhanced the anti-fungal performance of L. plantarum 14,917 in comparison to 1% glucose. GOS as the carbon source resulted in a less acidic environment in the C. albicans and S. mutans duo-species model and multispecies model where L. plantarum 14,917 was added. When GOS was utilized as the carbohydrate substrate, S. mutans and C. albicans had a significant reduction in the expression of the HWP1, ECE1, atpD, and eno genes (p &lt; 0.05). To our knowledge, this is the first study that reported the ability of GOS to neutralize S. mutans-C. albicans high caries of medium pH and to disrupt virulence gene expression. Moreover, as a prebiotic, GOS augmented the inhibitory ability of L. plantarum against C. albicans in vitro. The current study revealed the anti-caries potential of prebiotics GOS and shed light on novel caries prevention strategies from the perspective of prebiotics and probiotics. These findings provide a rationale for future biofilm or clinical studies to elucidate the effect of GOS on modulating oral microbiota and caries control.<\/jats:p>","DOI":"10.3390\/nu15092017","type":"journal-article","created":{"date-parts":[[2023,4,24]],"date-time":"2023-04-24T02:06:11Z","timestamp":1682301971000},"page":"2017","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Anti-cariogenic Properties of Lactobacillus plantarum in the Utilization of Galacto-Oligosaccharide"],"prefix":"10.3390","volume":"15","author":[{"given":"Xinyan","family":"Huang","sequence":"first","affiliation":[{"name":"Eastman Institute for Oral Health, University of Rochester Medical Center, Rochester, NY 14642, USA"},{"name":"School of Stomatology, Henan University, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6739-0806","authenticated-orcid":false,"given":"Jianhang","family":"Bao","sequence":"additional","affiliation":[{"name":"Eastman Institute for Oral Health, University of Rochester Medical Center, Rochester, NY 14642, USA"},{"name":"School of Stomatology, Henan University, Zhengzhou 450046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Zeng","sequence":"additional","affiliation":[{"name":"Eastman Institute for Oral Health, University of Rochester Medical Center, Rochester, NY 14642, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gina","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Arts and Science, University of Rochester, Rochester, NY 14627, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-0976-4655","authenticated-orcid":false,"given":"Xingyi","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Computational Biology, University of Rochester Medical Center, Rochester, NY 14642, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tong Tong","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Computational Biology, University of Rochester Medical Center, Rochester, NY 14642, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6428-2252","authenticated-orcid":false,"given":"Yanfang","family":"Ren","sequence":"additional","affiliation":[{"name":"Eastman Institute for Oral Health, University of Rochester Medical Center, Rochester, NY 14642, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Xiao","sequence":"additional","affiliation":[{"name":"Eastman Institute for Oral Health, University of Rochester Medical Center, Rochester, NY 14642, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"(2000).
