The size of the chromosome segment transduced by phage Pl.

Creator:: Cowan, Judith Harmon Miller
Abstract:: The purpose of this research was to determine whether the transducing phage Pl picks up original bacterial chromosome segments and whether these segments are always the same size. The plan of approach was to grow the donor bacteria Escherichia coli C600 gal⁺ (galactose) in minimal media containing the heavy isotopes...

Analysis of segregants of F'gal heterogenotes in Escherichia coli

Creator:: Kurahara, Carole Mahaney
Abstract:: The purpose of this study was to isolate and characterize any segregants of the heterogenotes formed from sexduction by an F' donor. Following the mating of F' W4520, carrying an F' gal₁⁺ gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a number of recombinant clones were picked and examined for...

A method for the isolation of canavanine by ion exchange

Creator:: Fujiwara, Allan
Abstract:: In 1959 Kitagawa discovered and isolated the amino acid, canavanine. Since its discovery much interest has been centered on this amino acid because of its biological aspects; e.g. canavanine has been shown to inhibit the growth of bacteria, viruses, protozoa, and cancer cells. The occurrence of canavanine is widespread in...

Relation of nitrogenous substances in rose leaves to powdery mildew resistance

Creator:: Bartlett, Allan B.
Abstract:: There is considerable variation among rose varieties in susceptibility to mildew, and as a result of maturation, leaves of most susceptible varieties become resistant to infection. The nature of resistance has been sought in various studies involving environmental, morphological, and physiological factors. An attempt was made in the present investigation...

A comparative study of Clostridium botulinum strains using differential egg yolk media

Creator:: Stiebrs, Anita
Abstract:: The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification of Clostridium botulinum type E strains, and to develop a more reliable method and media for the differentiation of this organism based on the "pearly...

A physiological approach to a rapid method for identifying C. botulinum

Creator:: Dyer, John Kaye
Abstract:: Disc gel electrophoresis of the vegatative cell -free extracts ofstrains of Clostridium botulinum types A, B, C, E, and F and therelated nontoxic group showed limited value as a means for identifyingthese closely related microorganisms, since separation,though not consistent in all cases, could only be based on the numberof protein...

An experimental investigation of transition pool boiling

Creator:: Aoki, Tadao
Abstract:: The heat-transfer phenomena studied in this work were associated with pool boiling from a flat horizontal surface facing upward with the bulk liquid at its saturation temperature. The analysis of boiling sound and the investigation of the transition boiling mechanism constituted the essence of the present study. The distinctively large...
