Six cave material samples from Dârninii Cave, Bihor Mountains, were microbiologically andenzymologically analyzed. The microbiological analyses consisted in determining the presence ofoligotrophs, aerobic heterotrophs, ammonifiers, nitrate and nitrite bacteria, denitrifiers and determining thepresence of micromycetes. In order to form a complete image on the microbial processes from this habitat,the bacteriological analyses were completed with quantitative and qualitative enzymological analyses. At allthe six samples of cave material the next quantitative enzymatic activities were performed: actual andpotential dehydrogenase, catalase and phosphatase. Only regarding the intensity of the processesdifferences were noticed. The qualitative enzymatic activities: amylase, dextranase, saccharase, maltaseand levanase, were not present at studied samples.
