Major Research Interests:

Functional foods with emphasis on probiotic properties and plant extracts.
Human physiological effects of lactic acid bacteria. Microbial physiology and ecology as well as pheno- and genotypic characteristics as background for probiotic effects of lactic acid bacteria.
Bifidobacteria and lactobacilli in the intestine and growth stimulation by specific growth factor.
Lactic acid bacteria as protective and starter cultures in foods.
Using modern molecular biology, microbiological diagnostics, selective media and methodological developments to identity bacteria in food and nature.
Microbiological contaminants in process equipment and in foods: HACCP- and GMP-concepts
Using LAB as biological control agents to inhibit a wide range of spoilage and mycotoxigenic molds, as well as inhibiting the production of a variety of mycotoxins.
Interaction between carbohydrates and milk protein for stabilization of soft drink products with long shelf life and their relationship to sensory quality and consumer acceptability.

Current Research:

Impact of emerging technologies on thermal inactivation of food borne pathogens.
Immobilization and evaluation of bacterial cells in bioreactor for the continuous production of value added products.
Isolation and characterization of food grade Bifidobacterium strains for probiotic formulation.
Novel biotechnological approaches to increase consumption of dairy foods among lactose-intolerance black American.
