Special Issue Information

Dear Colleagues,

The establishment of the beneficial interactions between humans and their microbiota is critical for the proper functioning of the organism considering microflora alterations can lead to a variety of disorders. The high number of microbial genes provides a wide spectrum of biochemical and metabolic activities that complement human physiology and have a significant impact on human health. Probiotic bacteria improve balanced microbial communities, exerting substantial health-promoting effects. This Special Issue of Metabolites, “Probiotic Bacteria: Metabolism and Impact on Human Health" will be dedicated to all aspects of using probiotics to treat diseases in humans, model organisms, or cell cultures. The goal of this Special Issue is to publish high quality research papers and provide a platform for all researchers, with the aim of better understanding the interaction between probiotic bacteria and human metabolism as well as the importance of their use as therapeutic strategies for diseases. We welcome original articles and reviews from various fields ranging from biochemistry and molecular biology to omics sciences, with a particular focus on metabolomics and metabolite biomarkers of beneficial interactions.

The gut–brain axis plays a role in major depressive disorder (MDD). Gut-bacterial metabolites are suspected to reduce low-grade inflammation and influence brain function. Nevertheless, randomized, placebo-controlled probiotic intervention studies investigating metabolomic changes in patients with MDD are scarce. The PROVIT study (registered at clinicaltrials.com NCT03300440) aims to close this scientific gap. PROVIT was conducted as a randomized, single-center, double-blind, placebo-controlled multispecies probiotic intervention study in individuals with MDD (n = 57). In addition to clinical assessments, metabolomics analyses (1H Nuclear Magnetic Resonance Spectroscopy) of stool and serum, and microbiome analyses (16S rRNA sequencing) were performed. After 4 weeks of probiotic add-on therapy, no significant changes in serum samples were observed, whereas the probiotic groups’ (n = 28) stool metabolome shifted towards significantly higher concentrations of butyrate, alanine, valine, isoleucine, sarcosine, methylamine, and lysine. Gallic acid was significantly decreased in the probiotic group. In contrast, and as expected, no significant changes resulted in the stool metabolome of the placebo group. Strong correlations between bacterial species and significantly altered stool metabolites were obtained. In summary, the treatment with multispecies probiotics affects the stool metabolomic profile in patients with MDD, which sets the foundation for further elucidation of the mechanistic impact of probiotics on depression.

The availability of omics data providing information from different layers of complex biological processes that link nutrition to human health would benefit from the development of integrated approaches combining holistically individual omics data, including those associated with the microbiota that impacts the metabolisation and bioavailability of food components. Microbiota must be considered as a set of populations of interconnected consortia, with compensatory capacities to adapt to different nutritional intake. To study the consortium nature of the microbiome, we must rely on specially designed data analysis tools. The purpose of this work is to propose the construction of a general correlation network-based explorative tool, suitable for nutritional clinical trials, by integrating omics data from faecal microbial taxa, stool metabolome (1H NMR spectra) and GC-MS for stool volatilome. The presented approach exploits a descriptive paradigm necessary for a true multiomics integration of data, which is a powerful tool to investigate the complex physiological effects of nutritional interventions.
