This work presents the results of microbiological investigations carried out in the Polish part of the Muskau Arch. In this abandoned lignite mining area highly acidified Fe\-rich waters have been formed as a result of sulphide oxidation. Microbiological tests have shown that all studied groups of microorganisms exhibit both time and spatial variability. The most common group of microorganisms are bacteria Galionella sp.

Results of microbiological research in the polish part of the Muskau Arch - the largest AMD environment in Poland - final report = Wyniki badań mikrobiologicznych prowadzonych w zbiornikach kwaśnych wód kopalnianych w polskiej części Łuku Mużakowa - największym tego typu środowisku w Polsce
