The thesis 'An in-vitro study of aerobic changes in silages' de-scribes some observations of microbial metabolic activities that occur during the initial phase of aerobic deterioration of silages. These processes still cause major problems in animal feeding due to their negative effect on the nutritional and hygienic quality of silage. In vitro batch cultures were used to simulate aerobic processes that occur in these lactic acid-fermented feeds, with measurements of pH, organic acids and ethanol being used as indicators of change in metabolic activity. The use of selective antibiotics made it possible to draw conclusions on the causative microbial groups. An unex-pected finding was the interaction and competition between two major bacterial and fungal representatives under semi-aerobic condi-tions.



Siriwan Martens, born 1975 in Cologne, studied Agroecology in Rostock from 1995-2001. The experimental work for the dissertation was done at the Institute of Crop and Grassland Science at the Federal Agricultural Research Centre (FAL) Braun-schweig and submitted to the Faculty of Agricultural and Environmental Sciences at the University of Rostock in October 2005.
