Bioremediation is a method of reviving enviroment which is using natural processes. These processes, the modern technology is trying to make faster and more effective. This diploma thesis deals with a theme about Microbial Activity of Soil influenced by different measurements of crude oil hydrocarbon contamination and observing of microbial consorcia activity in contamined, not contamined and sterile soil. The initial chapter deals with crude oil contamination and bacterial metabolism which is able to remove this contamination. There was executed a container trial in the experimental part of this thesis. The plants were planted into different types of adjusted soil (crude oil application, sterilization and so on). There was compared a production of biomass and there are a few conclusion from these results. The elementary thing is that the soil micro-organisms which appear in oil soil can make a life strategy in this enviroment and can also prosper which reflects on the production of biomass.The container trial was determined as the most exact method of soil activity valuation because it is nearest to the real soil proportion. Followingly there were executed analysis of store soil and analysis of so after finishng of the container trial. These results brought similar conclusions, however the cultivation on nutrient soil and the cultivation like that it is not comparable. The store soil underwent a water cress trial. This trial confirmed toxic effects of crude oil but it also showed the fact that crude oil is a natural substance and micro-organisms can adapt to it. The mineralization of soil was measured with help of ionic measurers.
