Abstract (german): 
In dieser Arbeit wurde der Einfluss von hohem Druck auf den bakteriellen Abbau von Erdölkomponenten in Hochdruckreaktoren untersucht. Abhängig von den untersuchten Modell-Stämmen und Erdölkomponenten wurden die Fähigkeit zum Abbau derselben und das bakterielle Wachstum durch hohen Druck entweder gefördert, gehemmt oder nicht beeinflusst. Hoher Druck veränderte außerdem die Zusammensetzung der bakteriellen Gemeinschaft in Tiefsee-Sedimenten. Diese Arbeit belegt, dass der Druck großen Einfluss auf den bakteriellen Abbau von Erdöl hat und in Untersuchungen des biologischen Erdölabbaus in der Tiefsee nicht vernachlässigt werden kann.
Abstract (english): 
In this thesis, the effect of high pressure on the ability of bacteria to degrade crude oil components was investigated in high pressure reactors. Depending on the analysed model strain and crude oil component, bacterial growth and degradation ability were either enhanced, inhibited or not affected by high pressure. Moreover, high pressure changed the composition of crude oil-degrading bacterial communities living in deep-sea sediments. This thesis proved that pressure is a crucial factor that cannot be neglected if we want to understand biodegradation of crude oil in deep-sea environments.
