In particular, four bacterial isolates (one isolate each of\n            <jats:italic>Arthrobacter<\/jats:italic>\n            sp.,\n            <jats:italic>Janthinobacterium<\/jats:italic>\n            sp.,\n            <jats:italic>Leifsonia<\/jats:italic>\n            sp., and\n            <jats:italic>Polaromonas<\/jats:italic>\n            sp.) were weathering associated. In comparison to what was observed in abiotic experiments, the presence of these strains caused a significant increase of granite dissolution (as measured by the release of Fe, Ca, K, Mg, and Mn). These most promising weathering-associated bacterial species exhibited four main features rendering them more efficient in mineral dissolution than the other investigated isolates: (i) a major part of their bacterial cells was attached to the granite surfaces and not suspended in solution, (ii) they secreted the largest amounts of oxalic acid, (iii) they lowered the pH of the solution, and (iv) they formed significant amounts of HCN. As far as we know, this is the first report showing that the combined action of oxalic acid and HCN appears to be associated with enhanced elemental release from granite, in particular of Fe. This suggests that extensive microbial colonization of the granite surfaces could play a crucial role in the initial soil formation in previously glaciated mountain areas.\n
