Microorganisms represent a heterogeneous group, widely spread in different environments. Our goal in this study was to determine whether microorganisms are present in four particular Transylvanian caves, which are: Ungurului Cave, Izvor Cave, Lesianei Cave, and Moanei Cave, all situated in the Pădurea Craiului Mountains. All of those caves are often visited by tourists. In order to conceive this study we have collected and analyzed different samples, using enzymatic and microbiological methods; the samples were taken from the floor deposits, wall deposits and sludge. Some enzymatic activities were studied, such as: catalase activity, phosphatase activity, actual and potential dehydrogenase activity, urease activity as well as the non-enzymatic catalytic activity. We have also computed the EISQ – which is the enzymatic indicator of soil or sludge quality – based on the results obtained by studying the enzymatic activities.
