Abstract A Botrytis cinerea strain isolated from glacier forefield sediment was able to release metabolites promoting element solubilization from sediments of glacier forefields on calcareous (Ca, Mg, Al, Mn) and siliceous (Ca, Al, Fe, Zn, Ni) bedrock. In calcareous glacier forefield sediment, solubilization efficiency for Al and Mn was about 2.5- and 1.3-fold higher with nitrate- compared to ammonium-N, respectively. In siliceous glacier forefield sediment, the efficiency of solubilization was enhanced by a factor of about 2.3 for Fe, 1.6 for Al, and 1.5 for Zn, respectively, in the presence of nitrate-N compared to ammonium-N. In the presence of a particular N-source (nitrate or ammonium, respectively), organic acids concentration, acidification and biomass of cultures were affected by the presence and the nature of the glacier forefield sediment present. Calcareous as well as siliceous glacial sediment exerted a stimulatory effect on the fungus.

硝酸盐和铵对灰葡萄孢菌对冰川前场沉积物对硅质和钙质基岩元素增溶作用的影响

摘要 从冰川前场沉积物中分离的灰葡萄孢菌菌株能够释放出促进冰川前场沉积物中元素溶解的代谢物，这些代谢物促进了钙质（Ca、Mg、Al、Mn）和硅质（Ca、Al、Fe、Zn、Ni）基岩上的沉积物的溶解。在钙质冰川前场沉积物中，Al 和 Mn 的溶解效率分别比铵-N 高约 2.5 倍和 1.3 倍。在硅质冰川前场沉积物中，与铵-N 相比，在硝酸盐-N 的存在下，Fe 的溶解效率分别提高了约 2.3、Al 的 1.6 和 1.5。在特定 N 源（分别为硝酸盐或铵）存在下，有机酸浓度、文化的酸化和生物量受到冰川前场沉积物的存在和性质的影响。钙质和硅质冰川沉积物对真菌产生刺激作用。
