Abstract
More efficient soybean wastewater treatment approach is necessary because of the increasing soybean processed in the worldwide. Aspergillus niger pellets formed during the wastewater treatment was a promising method from the views of easy harvest, safety authorized by FDA, and lower sludge obtained. For further COD removal on the base of A. niger pellets, a bacteria (Bacillus sp.) was isolated from sludge of classical soybean wastewater treatment. And then the absorption ratio was tested in different conditions for potential application in wastewater treatment. In this research, 76.24 % of Bacillus sp. was absorbed from the 3.0 × 108/mL initial cell concentration at pH 5.0. These results confirmed the possibility of further COD removal by the combination of A. niger and bacteria without losing the advantages of fungal pellets.
