Pentachlorophenol And Oxygen Consumption Of Immobilized Mixed Bacterial Culture, Tesfamariam Stephanos Tsadwa

Theses

This study was undertaken to investigate the effects of Pentachlorophenol (PCP) concentration on oxygen consumption of immobilized microbial cells. The microbial population, from a municipal wastewater treatment plant, was immobilized in calcium alginate gel. The following studies have also been conducted in this project:

1. Comparison of the effect of PCP concentration on oxygen uptake between immobilized and free cells.
2. Comparison of the effects of PCP concentration on oxygen uptake between acclimated and an unacclimated bacterial beads.

Dissolved oxygen concentration was monitored using a flow Clark-type oxygen probe, in a micro-assay bioreactor. It was found that PCP concentrations higher than 2000ppm …
