Biogeochemical cycling of gold involves dispersion and reconcentration of gold (Au) due to physical, chemical and biological processes in Earth surface environments. These processes are evocated by a metabolic activity of different microbial taxa but many of them (and also their biogeochemical potential) are still unexplored. Understanding the gold cycling is necessary for developing innovative, environmentally friendly gold processing techniques. Our experiments were aimed on isolation and identification of heterotrophic bacteria from ore and ore storage dump samples collected in Rozália gold mine in Hodruša-Hámre. Using culture-based approach followed by combination of MALDI-TOF MS protein profiling and 16S rDNA sequencing, 18 different bacterial genera were identified in studied microbiota. The participation of several representatives of these genera in individual gold cycling steps has already been reported. The real involvement of bacterial isolates in gold transformation reactions and their biogeochemical potential will be studied in subsequent experiments. [ABSTRACT FROM AUTHOR] |
