Aspergillus niger; RNA; adsorption; agricultural productivity; apatite; biogeochemistry; calcium carbonate; color; fungi; goethite; montmorillonite; oxalic acid; oxaloacetic acid; phosphorus; secretion; toxicity
Abstract:
... Phosphorus (P) deficiency limits agricultural productivity in many tropical and subtropical soils. The aim of this study was to investigate the influences of typical mineral components and microorganisms on P availability in soil. Three representative soil minerals, i.e., montmorillonite (Mt), calcium carbonate (Cal) and goethite (Gt) were incubated with phosphate-solubilizing fungus (PSF, Aspergi ...

Abstract:
... Mine tailings are major sources of metals and metalloids in the environment, making the physical and geochemical stabilization of tailings a serious environmental challenge. With a view to facilitate the development of covering vegetation and of decreasing the mobility of Pb in the acid tailings of a former Ag–Pb mine, laboratory microcosm experiments were performed to enable comparison of the eff ...

Abstract:
... This study compares the spatial and temporal variability of water colour for fifteen sub-catchments of the River Nidd, northeast England, in 1986 and 2006/2007. Between 1986 and 2006/2007, mean annual water colour increased in all the sub-catchments. However, there was considerable variation in the increase, which ranged from 22 to 155%. Statistical analysis revealed that the sub-catchments could ...
