Nutrition and microbial ecology of gastrintestinal tract

The program group P4-0097 involves researchers from the Department of Animal Science BF (Institute of Dairy Science and Probiotics, Chair of Microbiology and Microbial Biotechnology, Institute of Nutrition) and researchers Emona RCP Nutrition Research and Development Department. Programme group whose leader is Sen. Res. Assoc. Bojana Bogovič Matijašić, is funded by the SRA for the period 1.1.2019 - 31.12.2024.


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.

Our research group is 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).

Research packages:
  • Study of the degradation of plant and protein (structural) polymers by complex microbial communities and from aspects of process efficiency and interaction;
  • Nutritional requirements and effects of nutrients and plant bioactive substances (PBS);
  • Early human microbiota development and modulation of the gut microbiome with its metabolic interactions by application of probiotics and antibiotics.
