Immobilized enzymes in the biodegradation process of phenols and cyanides contained in industrial waste waters

Publisher:

Abstract:

The paper deals with removing phenols and cyanides from industrial waste waters, asa result of their biological degradation by means of ultrafiltration membranes with Immobilizedenzymes coming from bacterial strain Pseudomonas sp. The enzymatic membranes were obtainedby ultrafiltration of protein solution through a membrane made of polyacrylonitrile. In this way,above 90% of the enzymes were adsorbed onto the membrane surface. Such enzymaticmembranes were decomposed phenol and potassium cyanide in 70% and 80% respectively,during single ultrafiltration at the pressure of 1 10® Pa and at two fold reduction of initialvolume of waste waters. The retention coefficient of ultrafiltration process amounted to 100%for phenol and was above 90% for potassium cyanide.
