Özet:

 The current research investigated the bioaccumulation of NiII ions by Rhizopus delemar in molasses-containing fluids in a batch reactor. Due to the low pH requirements that R. delemar requires, it may grow in wastewater, which has an acidic pH. In the absence of NiII ions, the influence of pH and molasses concentration on the growth rate and concentration of R. delemar were examined. The highest level of microbial growth occurred at a pH of 4.0. Up to 20 gL of sucrose content increased the maximum R. delemar concentration and the specific growth rate. While the substrate content in each growing medium including molasses was kept constant at 10 gL, initial concentrations of metal ions were changed between 50 and 250 mgL to evaluate the bioaccumulation of NiII ions. It was discovered that when metal ions existed, the rate of microorganism growth slowed down as the metal ion concentration increased. The maximum growth rates were discovered to be 0.257 h-1 in the presence of 50 mgL NiII. When media containing 50 mgL NiII ions, the efficiency of NiII bioaccumulation was found to be 51.8.
