Microbial gene technology and food microbiology

ikbm

Laboratory of microbial gene technology and the food microbiology group at IKBM merged in May 2007 to form the group Laboratory of microbial gene technology and food microbiology. The group is headed by Professor Ingolf Nes.

The main research focus for this group is molecular microbiology, and lactic acid bacteria as well as pathogens are being studied. Of specific interest is the relation between probiotic and intestinal pathogenic bacteria. To unravel useful information concerning the behaviour of and interactions between such bacteria, the whole genome is studied by DNA microarray technology. The following species are studied:

Enterococcus faecalis
Enterococcus faecium
Staphylococcus aureus
Streptococcus pneumoniae
Lactobacillus sakei

The microarray platform is developed further along with new research issues coming up.

Another important and recognized area of research from this group is antimicrobial peptides (bacteriocins) produced by certain species. Gene regulation with respect to the production of such molecules is in focus, as well as temperate bacteriophages in Lactococci. Lactococci are used as a model organism and these studies are important to understand how the pathogenicity factors spreads among species.

The diversity of lactic acid bacteria an bifidobacteria in infants and piglets is another interesting project headed by members of this group.
