Structural analysis of thermally inactivated nisin

Creator:: Musafija-Jeknic, Tamara
Abstract:: Nisin, an antimicrobial peptide used in food preservation was evaluated for thermal stability. Nisin retained antimicrobial activity after having been heated at 121°C for seven hours. Anhydrous nisin and concentrated nisin solutions (5-10 mg/ml) were still active after having been heated up to 190°C or 230°C. When exposed to high...

Physiological, biochemical, and genetic studies on the [delta]²⁴ sterol methyltransferase of Saccharomyces cerevisiae

Creator:: McCammon, Mark Thomas
Abstract:: The role of the yeast S-adenosylmethionine: Δ²⁴-sterol-C-methyltransferase (SCMT) in sterol metabolism was investigated. Structural analogs of S-adenosylhomocysteine were tested for inhibition of the SCMT enzyme. A wide inhibitory range by these compounds was observed, indicating which structural features of the parent compound are important for binding to the enzyme. The...

Characterization of bacterial populations and turbidity effects in chlorinated drinking water

Creator:: LeChevallier, Mark W.
Abstract:: The present study was conducted as a three part investigation to (i) examine the incidence, distribution and kinds of standard plate count bacteria present in chlorinated and raw water; (ii) study the ecological role and possible health significance of Aeromonas spp. in distribution water, and (iii) evaluate the effects of...

Bdellovibrio metabolism of host macromolecules

Creator:: Engelking, Henry Mark
Abstract:: The genus Bdellovibrio is characterized by the unique ability to parasitize and enter gram-negative host bacteria. This interaction leads to the consumption and death of the host cell as the Bdellovibrio grows and divides into progeny. Little is known about the metabolism of host cell components by Bdellovibrio. The possibility...

Properties of the Glycoprotein of infectious hematopoietic necrosis virus

Creator:: Engelking, Henry Mark
Abstract:: The glycoprotein, G, of infectious hematopoietic necrosis virus, IHNV, was shown to be the viral protein which elicits and reacts with neutralizing antibodies. The G protein also confers protective immunity on immunized susceptible salmonid hosts to IHNV. The other three structural proteins of IHNV, N, Ml, and M2, do not...

Development of enteric protected vaccines for aquaculture

Creator:: Piganelli, Jon D.
Abstract:: At present all vaccines for fish are primarily delivered either by injection or immersion which introduces added stress and labor. A more attractive method of vaccine delivery is oral administration using an enteric protection system, Enteric Coated Antigen Microspheres (ECAMs), which can be utilized for a variety of antigenic forms....

Characterization of an inhibitor ("6S") of infectious pancreatic necrosis virus (IPNV) in normal rainbow trout serum (RTS) and its effects on the virus

Creator:: Park, Kyoung Chul
Abstract:: The characteristics of an inhibitor of infectious pancreatic necrosis virus (IPNV) found in normal rainbow trout serum (RTS) were studied. The serum inhibitor had a molecular weight of approximately 150 kDa and was dependent on divalent cations, either Ca²⁺ or Mg²⁺. It was stable at temperatures up to 50°C and...

Partial purification and properties of a columnaricin isolated from the myxobacterium Chondrococcus columnaris

Creator:: Needleman, David Sol
Abstract:: Of the 14 strains of Chondrococcus columnaris examined, 4 produced antagonistic substances that inhibited the growth of other strains of this species. The antagonistic substance produced by strain 3-P63-12 was examined in greater detail. Since the inhibitory substance had an extremely narrow spectrum of activity, and was not transmissible in...

Determination of differential gene action in Bdellovibrio bacteriovorus using RNA-DNA hybridization techniques

Creator:: Reed, Margaret Ann
Abstract:: In an attempt to study the times in the lifecycle of Bdellovibrio bacteriovorus at which various genes are transcribed, the patterns of messenger ribonucleic acid (mRNA) and ribosomal ribonucleic acid (rRNA) syntheses were examined using two different types of hybridization systems. The hybridization system using membrane bound deoxyribonucleic acid (DNA)...

Reef Microbiomes of Mo'orea, French Polynesia, a Socio-Ecological Island System

Creator:: McConnell, Kaitlin M.
Abstract:: At a time of rapid global change, a socio-ecological system (SES) approach can provide a framework through which to quantify and communicate the risks and uncertainties of coupled human-natural systems. Islands, and tropical coral reef islands in particular, can be excellent models for SES research since they may be considered...
