The gastrointestinal tract of humans and animals hosts an abundant and diverse community of microorganisms - intestinal microbiota, which is vital for the host (digestion, immune system ..). Nutrition plays an important role in the development of microbiota and microbiome (collective genome) of the gut. All over the world the research of microbiome is strongly encouraged in order to transfer these findings as quickly as possible in the applications in animal husbandry, in the protection of health, therapies and environmental protection.

The program Nutrition and microbial ecology of the gastrointestinal tract (P4-0097) is carried out at the Department of Animal Science BF (Biotechnical Faculty, University of Ljubljana) since 2004, in cooperation with the EMONA Nutrition Research & Development Department. The group, which is currently leaded by dr. Bojana Bogovič Matijašić brings together 17 researchers, 4 young researchers and 3 technicians from the Institute of Dairy Science and Probiotics, Chair of Microbiology and Microbial Biotechnology and Chair of nutrition. We are distinguished by interdisciplinarity, since among us are biologists, microbiologists, food technologists, zootechnics, biotechnologists, chemists and biochemists. We study how human and animal nutrition affects microorganisms in the gastrointestinal tract (microbiota, microbiome), through them the host organism (immune system, metabolism) and through animals also the nutritional value and quality of animal products. We also pay great attention to the study of the associated negative environmental impacts, through animal excreta and organic waste, which can be reduced by modulating the microbiota and through the degradation of organic substrates, with the simultaneous formation of biogas (methane, hydrogen).

Among the notable publications of the past three years, there are findings obtained with anaerobic hydrolytic bacteria biocultures for the decomposition of organic substrates (Čater in sod., 2015), on the effects of nanoparticles (TiO2) on the eukaryotic model organism Tetrahymena thermophila (Rajapakse in sod., 2016), on the genomes of Prevotella and their ability to metabolise polysaccharides (Accetto in sod., 2015), on the effect of the vegetarian diet on the intestinal microbiota (Bogovič Matijašić in sod., 2014) and on the effects of the synbiotic product on patients with irritable bowel syndrome (Bogovič Matijašić in sod., 2016). Among the publications in 2017, it’s worth mentioning especially the findings of the study of the influence of hypoxia and inactivity on the microbiota and the level of intestinal metabolites (Šket in sod., 2017; Šket in sod., 2017), the production of biogas from brewery spent grain (Panjicko in sod., 2017), the clinical research on the influence of probiotic yogurt consumption in lactose intolerant individuals (Roškar in sod., 2017), the effect of adding tannins to the pig diet (Rezar et al., 2017), the effects of the addition of α and γ tocopherol on the inflammatory processes and the metabolism of chickens (Korošec in sod., 2017) and the development of the baby's gut microbiota in the first three months of life (Obermajer in sod., 2017).
