چکیده انگلیسی
The aim of the current study was testing the performance of an economical phenol bioremoval method using Aspergillus versicolor and some agricultural wastes, which would supply the necessary carbon required by the process. The experiments were performed in a mineral salt medium containing glucose and sugars obtained from apple and carrot pomaces by acidic hydrolysis. The first experiments were designed to test the effects of different pH values and initial phenol concentrations on phenol bioremoval. The fungus succeeded to remove approximately 400Â mg/L initial phenol concentration with 61.5%, 98.7% and 100% removal yields in the medium containing 1Â g/L glucose, 1Â g/L apple pomace sugar and 1Â g/L carrot pomace sugar respectively at pH 6. The maximum specific uptake values found were 149.64Â mg/g, 261.88Â mg/g and 274.29Â mg/g at these conditions. The results showed that A. versicolor is a promising microorganism to tolerate higher concentrations of phenol.
