Research

Research Expertise

Food Microbiology and Probiotics

Research Interests 

Current research projects focus on the functional characterisation of lactic acid bacteria for use as starter cultures, protective cultures, or probiotics in food with a focus on cereal-associated lactic acid bacteria; production of oligosaccharides from sucrose or lactose by lactic acid bacteria and biological activities of oligosaccharides; novel, non-thermal preservation methods with a focus on high pressure processing and biopreservation; and intestinal microbial ecology with focus on the use of prebiotic carbohydrates and dietary fibre to improve host health.

Teaching

Undergraduate research or reading projects (NU FS 400 or NU FS 401) are offered throughout the year.

The selection of topics for undergraduate or summer projects varies depending on the interest of the student and the availability of mentors - please consult with Dr. Gänzle if you are interested in undergraduate research opportunities.

Announcements

Graduate Training Opportunities

Graduate students working with Dr. Gänzle typically have a background in Food Technology, Microbiology, or Food Chemistry. Students receive valuable training due to the multidisciplinary nature of his program and the interaction with scientists from other disciplines. Team members present regularly in the Food Microbiology Laboratory seminar, and typically have the opportunity to supervise undergraduate students and to present their research results at international conferences. 

Please consult http://www.afns.ualberta.ca/Graduate.aspx for questions about graduate programs at AFNS and inquire to Dr. Gänzle by e-mail regarding graduate training opportunities in his group.

Scholarly Activities

Research - Nomenclature, phylogenetic tree and physiological properties of lactobacilli

Left panel: Core genome phylogenetic tree of lactobacilli based on the phylogenomic analysis of concatenated alignment of protein sequences for the 114 single-copy core genes.

A version of the file is published as Figure 2 in Zheng et al., A taxonomic note on the genus Lactobacillus: Description of 23 novel genera, emended description of the genus Lactobacillus Beijerinck 1901, and union of Lactobacillaceae and Leuconostocaceae; Int. J. System. Evol. Bacteriol. https://doi.org/10.1099/ijsem.0.004107.

Current information on Lactobacillus nomenclature is also available on www.lactobacillus.ualberta.ca or www.lactobacillus.uantwerpen.be (mirrored websites that are periodically updated)


Right panel: Metabolic potential lactobacilli as indicated by the presence/absence of key enzyme genes for different pathways. Different colors of the heat map represent different gene sets: gray for lactic metabolism, blue for acid resistance, purple for oligosaccharide metabolism, green for peptidases, and red for bacteriocins. The figure was published as Figure 4 in Zheng et al., 2015. Genomic analysis of lactobacilli and pediococci demonstrates that phylogeny matches ecology and physiology. Appl. Environ. Microbiol. 81: 7233 – 7243. DOI: 10.1128/AEM.02116-15.
