Microbial activity in the subterranean environment of Dârninii Cave, Bihor Mountains.
Journal Title: Extreme Life, Biospeology & Astrobiology - International Journal of the Bioflux Society - Year 2009, Vol 1, Issue 1
Abstract
Six cave material samples from Dârninii Cave, Bihor Mountains, were microbiologically and enzymologically analyzed. The microbiological analyses consisted in determining the presence of oligotrophs, aerobic heterotrophs, ammonifiers, nitrate and nitrite bacteria, denitrifiers and determining the presence 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 all the six samples of cave material the next quantitative enzymatic activities were performed: actual and potential dehydrogenase, catalase and phosphatase. Only regarding the intensity of the processes differences were noticed. The qualitative enzymatic activities: amylase, dextranase, saccharase, maltase and levanase, were not present at studied samples.
