Microbial Characteristics Of An Activated Sludge And Three Commercial Preparations After Exposure To Phenolics, Laurie Gneiding
Theses
The biological characteristics of four microbial mixtures were examined after successive exposure to phenol and 2-chlorophenol at room temperature. One of the microbial mixtures was an activated sludge from the Livingston, NJ municipal wastewater treatment plant. The other three mixtures were commercial preparations sold by Polybac Corp.(Hydrobac), Sybron Corp. (BI-CHEM DC 1006/1007), and General Environmental Sciences(LLMO).
The characteristics examined were relative counts and species of gram negative/gram positive bacteria, yeast and fungi, protozoa, and higher organisms. For the gram negative bacteria and yeasts, culturing techniques and diagnostic tubes were used to determine the predominant species. Biochemical tests were done on …
