Media for identification and differentiation of Clostridium perfringens and Clostridium botulinum types a, b, and e

Creator:: Muniz, Juan Fermin
Abstract:: During the development of the media for the identification and differentiation of Clostridium perfringens and C. botulinum types A, B and E, 16 different double layer media were prepared and tested with known cultures of 28 C. botulinum strains, 20 C. perfringens strains and 11 other clostridial species. The semisolid...

Molecular characterization of crustacean parasite Nadelspora canceri

Creator:: Amogan, Harold
Abstract:: Investigations into the phylogeny, genome size, and karyotype of microsporidian Nadeispora canceri were initiated to further characterize the organism. Isolates of N. canceri spores were obtained from both Dungeness (Cancer magisrer) and red rock crabs (Cancer productus). Analysis of the ssu rDNA sequence from spore isolates of the two crab...

Germicide effectiveness and taxonomic studies on microbial isolates from meat and poultry plants

Creator:: Schwartz, James
Abstract:: A large number of bacterial and yeast isolates were obtained from meat and poultry processing plants by swab and contact plate sampling methods. Most of the isolates were subjected to a brief taxonomic study and listed according to their sources. Representative food spoilage, indicator and pathogenic organisms were identified to...

An ecological study of the lactic streptococci

Creator:: Radich, Paul Christian
Abstract:: In an attempt to determine the natural habitat of Streptococcus lactis, Streptococcus cremoris, and Streptococcus diacetilactis 27 different species of vegetables, 18 species of fruits and many individual cow raw milk samples were examined. S. lactis was found to occur on potatoes, corn, cucumbers, peas, beans, and cantaloupe. In each...

Thermally induced leakage and viability studies in an obligate psychrophilic marine bacterium

Creator:: Kenis, Paul Robert
Abstract:: Vibrio marinus MP-1, an obligate psychrophilic marine bacterium, was severely damaged when heat-shocked in the presence of nutrients. Thermally induced leakage materials from cells tested for in the medium were 260 mμ absorbing material (nucleic acids), orcinol reacting material (RNA), ninhydrin reacting material (amino acids), protein, malic dehydrogenase, and glucose-6-phosphate...

Factors that influence sulfide production in an estuarine environment

Creator:: Peterson, Paul Edward
Abstract:: Core samples from five sites in the Yaquina and Coos Estuary were assayed for vertical distribution of total sulfides, percent volatile solids, redox potential, particle size, total aerobic and sulfate reducing bacteria. Higher total sulfide levels were found at sites having more than four percent volatile solids, redox potential below...

The effects of hydrostatic pressure and temperature on the uptake and utilization of amino acids by a facultatively psychrophilic marine bacterium

Creator:: Paul, Kala Lapidus
Abstract:: The transport response of four marine psychrophilic bacteria to a variety of substrates was determined and related to environmental conditions. Studies on pressure and temperature effects on glutamic acid transport and utilization indicated that high pressures and low temperatures inhibit glutamate transport, while permitting glutamate respiration. Similar results were obtained...

Physical and chemical properties of some Bdellovibrio extracellular proteases

Creator:: Klubek, Brian Paul
Abstract:: Bdellovibrio bacteriovorus 100 and B. stolpii UKi-2 each produce two extracellular proteases which attack Azocoll (collagen) while B. starrii A3.12 produces at least four such proteolytic enzymes. Under standard growth and assay conditions each Bdellovibrio species produces a unique amount of proteolytic activity. The decreasing order of enzyme units was...
