1. Can the Fine Wheat Bran be a Betaine Source in Poultry Diets?
ABSTRACT The effect of fine wheat bran (FWB) as a methyl donor source on performance, metabolism, body composition and blood traits of growing broilers was studied. Three hundred and twenty broilers from eight to 28 d of age, distributed in a randomized block design, with five treatments and eight replicates of eight animals each were used. The experimental

2. Effects of Dietary Protein Level and Betaine Supplementation on Nutrient Digestibility and Performance of Japanese Quails
ABSTRACT This study investigated the effects of dietary protein levels and betaine supplementation on nutrient digestibility and performance of Japanese quails. In total, 765 Japanese quails were randomly assigned to a 3×3 factorial arrangement, with five replicates of 17 quails each. Three basal diets were formulated to contain three crude protein levels (

3. Effect of dietary betaine supplementation on the performance, carcass yield, and intestinal morphometrics of broilers submitted to heat stress
The objective of this study was to evaluate the effect of betaine in methionine- and choline-reduced diets fed to broilers submitted to heat stress. In total, 1,408 male broilers were randomly distributed into eight treatments, according to 2 x 4 (environment x diet) factorial arrangement, with eight replicates of 2 birds each. Birds were reared environmenta

4. Efeitos da suplementação de betaína, combinada ou não com a suplementação de creatina, sobre a força máxima, potência e concentrações intramusculares de fosforilcreatina, em indivíduos não treinados em força / Effects of betaine supplementation, combined or not with creatine supplementation on maximal strength, power output and muscle phosphorylcreatine content in non-resistance trained subjects
A betaína é um trimetil derivado do aminoácido glicina. Os seus principais efeitos fisiológicos são atuar como um osmólito e como doador de radicais metil. Especulase que a betaína possa contribuir para a síntese de creatina no músculo esquelético pelo fornecimento de grupos metil, resultante da conversão de betaína em dimetilglicina, para a reme

5. Porphyrin Overproduction by Pseudomonas denitrificans: Essentiality of Betaine and Stimulation by Ethionine
Ethionine supplementation of a defined medium for growth of Pseudomonas denitrificans inhibited vitamin B12 overproduction and led to the elaboration of a red pigment. The pigment was shown to be coproporphyrin III. Inhibition by ethionine of cobalamin synthesis is probably due to interference of methylation of the corrin nucleus by methionine. Accumulation

6. Genetic Engineering of Glycinebetaine Production toward Enhancing Stress Tolerance in Plants: Metabolic Limitations1
Glycinebetaine (betaine) affords osmoprotection in bacteria, plants and animals, and protects cell components against harsh conditions in vitro. This and a compelling body of other evidence have encouraged the engineering of betaine production in plants lacking it. We have installed the metabolic step for oxidation of choline, a ubiquitous substance, to beta

7. Choline Derivatives Involved in Osmotolerance of Penicillium fellutanum†
Penicillium fellutanum is osmotolerant and xerotolerant when cultured in a low-phosphate medium containing 3 M NaCl. Glycerol and erythritol accumulated in cultures with NaCl concentrations up to 2 M; glycerol was the only detectable polyol in cultures containing 3 M NaCl. In cultures with 3 M NaCl, the intracellular levels of glycine betaine and choline-O-s

8. Effects of particulate materials and osmoprotectants on very-high-gravity ethanolic fermentation by Saccharomyces cerevisiae.
The effects of osmoprotectants (such as glycine betaine and proline) and particulate materials on the fermentation of very high concentrations of glucose by the brewing strain Saccharomyces cerevisiae (uvarum) NCYC 1324 were studied. The yeast growing at 20 degrees C consumed only 15 g of the sugar per 100 ml from a minimal medium which initially contained 3

9. Transposable Elements: Targets for Early Nutritional Effects on Epigenetic Gene Regulation
Early nutrition affects adult metabolism in humans and other mammals, potentially via persistent alterations in DNA methylation. With viable yellow agouti (Avy) mice, which harbor a transposable element in the agouti gene, we tested the hypothesis that the metastable methylation status of specific transposable element insertion sites renders them epigenetica

10. Osmosensitivity Associated with Insertions in argP (iciA) or glnE in Glutamate Synthase-Deficient Mutants of Escherichia coli
An ampicillin enrichment strategy following transposon insertion mutagenesis was employed to obtain NaCl-sensitive mutants of a gltBD (glutamate synthase [GOGAT]-deficient) strain of Escherichia coli. It was reasoned that the gltBD mutation would sensitize the parental strain even to small perturbations affecting osmotolerance. Insertions conferring an osmos

11. Role of Ectoine in Vibrio cholerae Osmoadaptation
Vibrio cholerae is both an intestinal pathogen and a microbe in the estuarine community. To persist in the estuarine environment, V. cholerae must adjust to changes in ionic composition and osmolarity. These changes in the aquatic environment have been correlated with cholera epidemics. In this work, we study the response of V. cholerae to increases in envir

12. Identification and Characterization of an ATP Binding Cassette l-Carnitine Transporter in Listeria monocytogenes
We identified an operon in Listeria monocytogenes EGD with high levels of sequence similarity to the operons encoding the OpuC and OpuB compatible solute transporters from Bacillus subtilis, which are members of the ATP binding cassette (ABC) substrate binding protein-dependent transporter superfamily. The operon, designated opuC, consists of four genes whic
