Abstract
ABSTRACT The influence of Aspergillus tubingensis to vegetation establishment on bauxite residue and its effects on the native arbuscular mycorrhizal fungal (AMF) colonization were studied. An alkali tolerant bermudagrass (Cynodon dactylon) adapted to local conditions was grown in bauxite residue with different amendments with and without A. tubingensis. Amendments of bauxite residue positively affected the growth of bermudagrass, especially when amended with gypsum and sludge. Gypsum- and sludge-amended treatments inoculated with A. tubingensis had maximum above-ground biomass, nutrient uptake, and reduced accumulation of metals. The native AMF colonization also increased because of A. tubingensis inoculation. The results of the present study suggest that A. tubingensis has the potential to improve the establishment of vegetation and neutralization of bauxite residue, especially when amended with gypsum and sludge.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
