1. The genetics of antibiotic production and the role of antibiotics in biological control of Erwinia amylovora by Erwinia herbicola
Abstract : Erwinia herbicola is an epiphyte of apple and pear with potential as a biocontrol agent of Erwinia amylovora, which causes fire blight. This research aimed to assess the relative role of antibiotics produced by E. herbicola, Eh318 as a mechanistic basis for biocontrol. READ MORE

2. Nitrogen fixation among marine bacterioplankton
Abstract : While bacterioplankton indisputably control vital biogeochemical paths in the cycling of carbon and nutrients in the world’s oceans, our knowledge about the functional and genetic diversity of bacterioplankton communities is negligible. In this thesis, molecular and more traditional microbiological methods were used to study the specific function of N2-fixation and in a general sense diversity of marine bacterioplankton species.

3. The effect of honeybee-specific lactic acid bacteria on american foulbrood disease of honeybees
Abstract : The honeybee, Apis mellifera, is one of the most economically important pollinators and highly valued for its honey and wax production. Managed honeybees occupy an increasingly critical role in agricultural productivity and food security. READ MORE

4. Lactic acid bacterial symbionts from the honeybee: Characteristics and applications in wound management
Abstract : Antibiotic resistance is now a large threat with worldwide agreement that we will fall into a post-antibiotic era unless there is suitable treatment alternatives discovered. In recent years, chronic wounds have become a major burden on society and treatment is complicated. READ MORE

5. Molecular determinants of disease severity in urinary tract infection
Abstract : In the urinary tract, Escherichia coli infection may result in life-threatening disease, or asymptomatic bacterial carriage, comparable to bacterial commensalism in the gut. Pathogenic strains trigger a disease provoking host response which differs depending on the infected organ. READ MORE
