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 nigerX300

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.
