Senior Scientific Officer



Head of Laboratory of Anaerobic Microbiology


My studies started with rumen proteolytic, amylolytic and cellulolytic microbes and their hydrolytic enzyme production. Following years I was dealing with rumen microbes adhesion to feed particles. We introduced methods for anaerobic microbiology and developed probiotics for in vivo testing. Then we moved to biochemistry of rumen bacterium Butyrivibrio fibrisolvens and rumen fungi and interactions of rumen microbes in vitro and in vivo. It led to the development of enzymatic method for estimation of protein degradation in the rumen and feed digestibility for ruminants. I took a part in transformation of anaerobes. I was able with a shuttle vector with fluoroacetate dehalogenase to transform a many Pseudobutyrivibrio isolates. Transformation of undescribed isolates directed me to taxonomy of butyrate-producing bacteria and description of two new species: Butyrivibrio hungatei, Pseudobutyrivibrio xylanivorans. I was involved in description of Butyrivibrio proteoclasticus, later on.

Knowledge of butyrate-producing bacteria helped me to map changed microbiome in patients with the human bowel diseases: we described the effect of Inflammation Bowel Disease and Celiac Disease and we able to show the importance of probiotic treatment. It was possible to describe Bifidobacteria gut colonization in newborns, calves as well as in social insect digestive tract.

In last decade, we have detected presence of bifidobacteria in most vertebrates and many insect species. In frame of this, we described new bifidobacteria in the gut of bumblebees: Bifidobacterium bombi, B. bohemicum and B. actinicoloniformis and a new genus Bombiscardovia (Bombiscardovia coagulans).
