Bioconversion of domestic wastewater sludge by immobilized mixed culture of Penicillum corylophilum WWZA1003 and Aspergillus niger SCahmA103

The bioconversion of domestic wastewater sludge by immobilized mixed culture of filamentous fungi was investigated in a laboratory. The potential mixed culture of Penicillium corylophilum WWZA1003 and Aspergillus niger SCahmA103 was isolated from its local habitats (wastewater and sludge cake) and o...
