1. A pure strain of thyroid epithelium was isolated and maintained in active condition for 7 months. At the end of the experiment, the rate of cell multiplication was as great as at its beginning. 2. The thyroid cells grew at the surface of the coagulum as pavement epithelium, and within the coagulum as a glandular structure. 3. The cells did not dedifferentiate, and the lumen of the acini in c...

To understand the plastic ̄ow behavior of commercially pure vanadium under high strain rates, uniaxial compression tests of cylindrical samples are performed using UCSD's enhanced Hopkinson technique. True strains exceeding 50% are achieved in these tests, over a range of temperature from 77 to 800 K at the strain rates of 2500 and 8000 sÿ1. The microstructure of the deformed and undeformed sam...

Production of bacterial cellulose by Acetobacter xylinum ATCC 10821 and 23770 in static cultures was tested from unamended food process effluents. Effluents included low-solids (LS) and high-solids (HS) potato effluents, cheese whey permeate (CW), or sugar beet raffinate (CSB). Strain 23770 produced 10% less cellulose from glucose than did strain 10821 and diverted more glucose to gluconate. Un...

This study aimed to investigate the biological activity of aqueous mixtures two essential oils. The were prepared by mixing certain amounts lavender and clove oils with distilled water at room temperature. In case oil, a relatively clear saturated phase was obtained after an excess oil. oil formed stable oil-in-water emulsions. antibacterial samples tested against model bacterial strains. growt...

9 PCR amplification of pure bacterial DNA is vital to the study of bacterial interactions 10 with corals. Commonly used bacterial-specific primers 8F and 27F paired with universal 11 primer 1492R amplify both eukaryotic and prokaryotic rDNA. An alternative primer set, 12 63F/1542R, is suggested to resolve this problem. 13

Vibrio coralliilyticus is an important coral pathogen demonstrated to cause disease outbreaks worldwide. This study investigated the feasibility of applying bacteriophage therapy to treat the coral pathogen V. coralliilyticus. A specific bacteriophage for V. coralliilyticus strain P1 (LMG23696), referred to here as bacteriophage YC, was isolated from the seawater above corals at Nelly Bay, Magn...

Previous winery-based studies showed the strains Lalvin® RC212 (RC212) and Lalvin® ICV-D254 (D254), when present together during fermentation, contributed to >80% relative abundance of the Saccharomyces cerevisiae population in inoculated and spontaneous fermentations. In these studies, D254 appeared to out-compete RC212, even when RC212 was used as the inoculant. In the present study, under co...

This paper is the first report of the impact on the bacterial community in the midgut of the Asian corn borer (Ostrinia furnacalis) by the chitinase from the transgenic Trichoderma strain. In this study, we detected a change of the bacterial community in the midgut of the fourth instar larvae by using a culture-independent method. Results suggested that Proteobacteria and Firmicutes were the mo...

Two novel protocols for the chemical valorization of polyhydroxybutyrate (PHB) were developed, aiming at production two bio-based molecules: methyl 3-hydroxybutyrate (MHB) and 3-methoxybutyrate (MMB). Optimized reaction conditions applied to pure PHB inclusions inside bacterial cells as starting materials. MHB was synthesized through a single-step catalytic methanolysis, while MMB three-step pr...
