Studies on the Pattern of Changes in Glucose Concentration, Initial pH and Nitrogen Content in the Synthetic Medium during Fungal Growth and as (III) Biosorption by Aspergillus niger X₃₀₀

An experimental study was conducted to evaluate the pattern of changes in glucose, pH, and nitrogen profile in the synthetic medium as a function of fungal growth and As(III) biosorption by an As(III) resistant fungus Aspergillus niger X₃₀₀. Glucose is continuously consumed, amino nitrogen increased up to 7^th day, ammonical nitrogen increased continuously along with the sharp decrement of residual nitrogen in the broth.
