Special Issue Information

Dear Colleagues,

This Special Issue focuses on the versatile bioactivities and molecular mechanisms of probiotics and their metabolites. Probiotics and their metabolites can interact with various gastrointestinal components (from oral cavity, stomach, gut, etc.) to maintain physiological homeostasis, including intestinal microenvironment regulation, gut microbiota interference, biological barrier formation, epithelial cell metabolism intervention, and so on. In addition, probiotics and their metabolites also exert diverse bioactivities to participate in diseases pathogenesis, development and prognosis, directly or via various “digestive system–organs” axes; these include anti-inflammation, anti-oxidation, anti-obesity, hypoglycemic and anti-tumor activities, among others. Moreover, probiotics/metabolites also interact with food digests to play a crucial role in nutrition, digestion, absorption and metabolism. Revealing the efficacy and corresponding interactions between probiotics/metabolites with gastrointestinal components will promote the comprehensive understanding of this topic, the development of innovative strategies and the advancement of promising applications for future probiotics-mediated health interventions. Original research articles, short communications, and reviews are all welcome in this Special Issue.

We look forward to receiving your contributions!

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs).

The interplay between enterohepatic circulation and the gut microbiota is the main driver determining systemic levels of estrogens and their metabolites. Nevertheless, the role of potentially probiotic microorganisms in estrogen metabolism has not been investigated so far. In this work, we have explored the ability of six Ligilactobacillus salivarius strains isolated from human milk and vaginal samples to degrade and/or conjugate parental estrogens in vitro and under aerobic conditions. The quantification of estrogens and their derivatives was carried out in cell-free supernatants by LC-QQQ-MS. All the tested L. salivarius strains achieved an average degradation rate of estrone and estriol of 98% and 55%, respectively, whereas 17β-estradiol was preferentially conjugated (up to 40%). The presence of seven out of ten genes encoding enzymes relevant for estrogen metabolism was further confirmed by PCR, highlighting their genetic potential for degrading, conjugating and/or deconjugating estrogens. The tested L. salivarius strains may be considered potential probiotics affecting the fate of endogenous estrogens. Clinical trials targeting populations with estrogen-dependent conditions will be required to elucidate the true potential of these strains for the restoration and maintenance of a healthy host estrobolome.
