Significance of pigments in radiation resistance of Micrococcus radiodurans

Creator:: Krabbenhoft, Kenneth Louis
Abstract:: An ecological study of a microorganism similar to that isolated in 1956 and designated as Micrococcus radiodurans indicated that the organism could be isolated from several different environments. By taking advantage of its radio-resistivity, high levels of gamma radiation were used in the isolation procedures to inactivate most of the...

The response of nitrifying bacteria to treatments of N-Serve and Roundup in continuous-flow soil columns

Creator:: Rhodes, Albert N.
Abstract:: This study examined the effects of Roundup [N-(phosphonomethyl) glycine] and N-Serve [2-chloro-6- (trichloromethyl) pyridine] on nitrifying organisms in static batch, perfusion soil columns, and a new continuous-flow soil column system. The continuous-flow method is new to nitrification studies and was shown to produce greater nitrifier activity than either static batch...

The site of action of radio-lethal compounds on Micrococcus radiodurans

Creator:: Manes, Jasper Damon, Jr.
Abstract:: Iodoacetic acid and diphenylamine were used in this study to elucidate the mechanisms of resistance of Micrococcus radiodurans to radiation. This organism, a gram positive, non-spore forming, salmon-pink, tetracoccus has a LD₅₀ of 213,000 R when grown in the absence of radio-modifying agents. M. radiodurans, when grown in media containing...

A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

Creator:: Ley, Ronald Douglas
Abstract:: Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

The irradiation resistance of food pathogens contaminating seafoods

Creator:: Dutiyabodhi, Pisawat
Abstract:: Studies have been made to determine the limits of tolerance to gamma radiation for 15 cultures of the following bacterial species both in culture media and in irradiation-sterilized seafoods (crab-meat, halibut and shrimp) inoculated with Salmonella (seven species), Shigella (three species), and one species each of Neisseria, Myco-bacterium, Esctrerichia, Proteus...

Effects of neutron irradiation on high-purity vanadium

Creator:: Stevens, Richard Francis, Jr.
Abstract:: Because of the potential elevated-temperature applications of high-purity vanadium in nuclear reactors an investigation was conducted to determine the effects of nuclear irradiation upon the properties of the pure metal. The results of this investigation indicated that the effects caused by irradiation, increased strength and hardness and decreased ductility, could...

Modeling of the thermal behavior of irradiated sphere-pac mixed carbide fuel

Creator:: Ades, Maurice
Abstract:: Several fuels are being investigated for fast breeder reactor applications. One promising concept is sphere-pac mixed carbide fuel. As a part of the development of this fuel concept it is necessary to determine the behavior of the irradiated fuel for safe and reliable operation on a sound economic basis. It...
