Identifying coevolution of class IIa bacteriocin and their immunity protein
Kroken, Gard (Master thesis, 2018)Class IIa bacteriocins are Antimicrobial peptides found in many lactic acid bacteria. Here they serve as a weapon against competing bacteria by causing cell leakage through pore-formation in the membrane. An immunity protein ... -
The impact of impaired biosynthesis of menaquinone on biofilm and macrocolony formation in Staphylococcus aureus
Olsen, Henriette Sætre (Master thesis, 2021)Staphylococcus aureus (S. aureus) is known to cause biofilm-associated infections in humans. Biofilms are surface associated microbial communities and is characterized as three-dimensional structures with cells embedded ... -
Karakterisering av Fusiformicin : et nytt antimikrobielt stoff med aktivitet mot Streptococcus pneumoniae
Sandegren, Vilde (Master thesis, 2022)Antibiotikaresistens regnes som et av de største problemene som verden står ovenfor i dag i forhold til global helse, matsikkerhet og utvikling. Det arbeides med å finne nye antibiotika med aktivitet mot bakterier som ... -
