Novel concepts in biological plant protection on the basis of the biological control agent Serratia plymuthica HRO-C48 Neue Konzepte für den biologischen Pflanzenschutz am Beispiel des Biological Control Agents Serratia plymuthica HRO-C48 Dissertation zur Erlangung des akademischen Grades doctor rerum naturalium (Dr. rer. nat.) der Mathematisch-Naturwissenschaftlichen Fakultät der Universität Rostock Henry Müller geb. am 17.08.1976 aus Rostock Oktober, 2006 urn:nbn:de:gbv:28-diss2008-0119-6 Gutachter: Prof. Dr. Gabriele Berg Technische Universität Graz Institut für Umweltbiotechnologie Petersgasse 12 A-8010 Graz Prof. Dr. Hubert Bahl Universität Rostock Institut für Biowissenschaften Mikrobiologie Albert-Einstein-Straße 3 D-18059 Rostock IIAbstract For ecological and economical reasons the management of soil-borne diseases in agriculture by conventional pesticides is limited. Environmentally friendly alternatives such as the employment of microbial antagonists to control phytopathogens are of growing interest. Inconsistent performance of the microorganisms, however, has hampered commercial application of biological control agents (BCAs). One of the main problems is to achieve an active and stable colonization of the plant root by the introduced microorganism.
