| Abstract |
Experimental techniques were developed for use in determining the qualitative changes in the aerobic heterotrophic bacterial populations in raw domestic sewage. Mixed bacterial flora are subject to various ecological pressures such as the availability of metabolizable nutrients. Certain populations may be at a competitive disadvantage because other organisms have a more versitile metabolism which enables preferential utilization of nutritional substrate, alteration of the growth environment through production of metabolic products inhibitory to other organisms, and changes in pH and available oxygen. A raw sewage sample was selected as the model system and held under controlled laboratory conditions. The initial mixed populations emerged into homogeneous populations without overall change in the rate of dissimilation of substrate. The pH decrease seemed to be an important factor in the selection pressure. |
