Enzymatic Decolorization of Dye-polluted Water Using Natural Cellular Carriers 66th Canadian Chemical Engineering Conference/2016

Mohammed, I.; Schubert, M.; Hampel, U.

In the current years increasing efforts have been done to develop sustainable processes with smaller ecological footprint, which is. to decrease the industrial pollution and the environmental impact.
One serious pollutant that results from the textile industry etc. is the increasing usage of dyes. The treatment of dye-polluted water is still challenging since today's methods, such as absorption and membrane filtration, have their limitations.
The application of biocatalysts represents a sustainable solution as it results in nontoxic products at comparable eco-friendly treatment costs. In particular, oxidation enzymes, such as laccase, which can oxidize dye are in the scope. However, direct application of laccase enzyme is not favorable because it requires processes to recover the enzyme, while enzymes, immobilized on the carrier can be re-used as long as the activity is sufficiently high.
Loofa is a natural-grown material of the cucumber family, which provides attractive morphological properties. Moreover, loofa carrier can be decomposed after the process without additional treatment and is inexpensive.
In the contribution, the developed laccase immobilization methodology and the optimization of the immobilization using the Response Surface Methodology (RMS) will be discussed. Furthermore, the capability to degrade dye-polluted water will be evaluated and a novel bioreactor for the water treatment will be suggested
