Sumario: | Biological treatment with fungi has proven to be an attractive process for biodegrading textile
effluents. In this work a parametric study of the degradation of Direct Black 22 (DB22) by
P. chrysogenum was made as a first approach to an industrial application. Three additional
carbon sources and their optimum initial concentration were studied. The optimum carbon
source concentration was determined using glucose; 6 g/L showed the best performance.
With this value alternative carbon sources were studied: glucose as control, starch because
it is a by-product of the local potato industry and effluent from the same industry because it
is a residue. The use of potato starch as co-substrate showed the highest rates of
decolorization and COD degradation. This study concludes that the use of potato starch with
an initial concentration of 6 g/L is the most favorable option. |
