Abstract

This study has shown the effect of camel's urine on the growth and some other metabolic activities of Aspergillus niger. The results proved that the effect on metabolic of A. niger depended on the camel's urine concentration and the fungal age. The results further indicated that the lower concentration of camel's urine had a stimulative effect on glucose uptake. This effect decreased with the progress of fungal culture age, while 4 % and 6 % of the camel's urine had a suppressive effect glucose uptake. The lower concentrations lead to the highest suppression in nitrate uptake by the fungus, however, the effect decreased until it turned into a progressive stimulative effect until the age of fungal culture reached the sixth day. The amount of amino acids secreted, increased in the nutrient media in concentrations used. This increase was synchronized with the concentration, whereas the stimulative effect turned to an inhibitory one with the progress of fungal culture age.
