Microbial Characteristics Of An Industrial Mixed Liquor After Exposure To Phenolic Compounds, Patricia L. Boyle

Theses

The microbial characteristics of a mixed population from the Passaic Valley Sewerage Commissioners (PVSC) Wastewater Treatment Plant in Newark were examined. This plant handles about 250 million gallons per day of mixed sewerage, with a large industrial component. The microbial species were characterized using standard plating techniques, morphology, microscopic observation, and biochemical tests. These characteristics were determined for the fresh liquor, and after successive batch exposure to phenol (100 ppm) and 2-chlorophenol (20 ppm). Predator/prey, gram positive to gram negative bacteria ratios, and the fungi and protozoan populations were also determined. These results were compared with those previously obtained using …
