Interactions In Lambdoid Bacteriophage Populations, Bruce Edward Mitchell
Interactions In Lambdoid Bacteriophage Populations, Bruce Edward Mitchell
Masters Theses
The lambdoid bacteriophages are ideal subjects for the study of populational interactions at the molecular level because they do not mutually exclude one another in mixed infection of the same host cell. Previous work done in this laboratory using the lambdoid phage pairs λ-434 hy mi and λ-∅80 have demonstrated a density-dependent reduction in progeny yield per infected cell (burst size) as a function of increasing multiplicity of infection (m.o.i.). The λ cI gene which codes for the repress or molecule has been demonstrated to be the cause of the interaction in the λ-434 hy mi phage pair. …
The Effects Of Residual Chlorine On Selected Microflora Of Kickapoo And Cassell Creek, James A. Mcgaughey
The Effects Of Residual Chlorine On Selected Microflora Of Kickapoo And Cassell Creek, James A. Mcgaughey
Masters Theses
The survival of fecal coliforms, fecal streptococci, and heterotrophs after exposure to chlorine were compared in receiving waters of the Mattoon and Charleston, Illinois waste treatment facilities employing membrane filter techniques and Standard Plate Counts. Water samples were taken from receiving waters upstream from the treatment plant, from secondary effluent and chlorinated secondary effluent within the plant, and from downstream receiving waters. Stream flow contribution and plant effluent contribution required the calculation of dilution factors to determine expected numbers of the various microflora found downstream assuming no residual chlorine effect. Total chlorine concentration was measured by amperometric titration at the …
