1. Gut microflora and intestinal morphology changes of broiler chickens fed reducing dietary protein supplemented with lysine, methionine, and threonine in tropical environment
ABSTRACT This experiment aimed to discover the effect of reducing dietary protein supplemented with lysine, methionine, and threonine on growth performance, volatile fatty acid profile, and intestinal villus height and crypt depth of broilers, as well as the microflora counts isolated from broiler chicken faeces. A total of 288-day-old broilers were allocate

2. GABAergic effect of valeric acid from Valeriana wallichii in amelioration of ICV STZ induced dementia in rats
ABSTRACT Valeriana wallichii DC., Caprifoliaceae, is used to have anti-ulcer, anti-spasmodic, anti-epileptic, memory enhancer, anti-anxiety, anti-rheumatic, sedative, anti-asthmatic and diuretic activities. V. wallichii is reported to contain valpotriates, valeric acid, valerenic acid, valechlorine, valerianine, resins and alkaloids. Valeric acid, found in V

3. INGESTÃO DA TINTURA DE VALERIANA OFFICINALIS PROTEGE DA DISCINESIA OROFACIAL INDUZIDA POR RESERPINA EM RATOS / INTAKE OF THE VALERIANA OFFICINALIS TINCTURE PROTECTS AGAINST OROFACIAL DYSKINESIA INDUCED BY RESERPINE IN RATS
Considerando as hipóteses do papel da neurotransmissão gabaérgica e do estresse oxidativo no desenvolvimento de movimentos orais associados a neuropatologias importantes, o presente estudo investigou a possível habilidade da tintura de V. officinalis na prevenção dos movimentos de mascar no vazio (MMV) induzidos por reserpina em ratos. Os animais foram

4. AvaliaÃÃo morfofisiolÃgica da absorÃÃo e metabolizaÃÃo de Ãcidos graxos volÃteis pelo proventrÃculo de bovinos. / Morphophysiologic evaluation of the absorption and metabolism of volatile fatty acids by bovine forestomach.
About 60% of volatile fatty acids (VFA) produced in reticulorumen are absorbed in this compartment. The other 40% pass with the fluid phase to the omasum and are absorbed before entering the duodenum. Two experiments were carried out to determine the absorption surfaces and the VFA absorption and metabolism capacity of the bovine forestomach compartments. In

5. Sintese enzimatica dos esteres de aroma butirato e valerato de citronelila por lipase de Rhizopus sp. / Enzymatic synthesis of the butyric flavor esters and valeric citronellyl by lipase of Rhizopus sp.
The enzymatic synthesis of citronellyl flavor esters with a non commercial lipase from Rhizopus sp was investigated. The results were compared with other lipases from Fusarium 152 B, Fusarium 160 A1, Tricoderma sp, and Alcaligenes sp. The lipase from Rhizopus sp was selected as better biocatalyst for the citronelyl ester synthesis. It was verified the effect

6. Function of the Glyoxylate-condensing Enzymes I. Growth of Escherichia coli on n-Valeric Acid
Growth of Escherichia coli E-26 on valeric acid results in the formation of a mutant population characterized by the ability to form constitutively several glyoxylate-condensing enzymes. This mutant also differs from the parent organism in the ability to effect rapid growth on a series of short-chain fatty acids. These mutants were utilized in postulating ge

7. Detection of Clostridium difficile in faeces by direct gas liquid chromatography.
Stool specimens examined for the presence of Clostridium difficile and its cytotoxin were screened by gas liquid chromatography for the presence of volatile fatty acids and p-cresol. Twenty seven of 110 (25%) stools yielded C difficile or cytotoxin; iso-valeric acid was detected in 63/110 (57%) and iso-caproic acid in 18/110 (16%) stools. Para-cresol was fou

8. Volatile Fatty Acid Requirements of Cellulolytic Rumen Bacteria1
A gas chromatographic method was developed which could separate the isomers isovaleric and 2-methylbutyric acid. Subsequent analyses revealed that most commercially available samples of these acids were cross-contaminated; however, one sample of each acid was found to be pure by this criterion. The growth response of seven strains of cellulolytic rumen bacte

9. INCORPORATION OF ISOBUTYRATE AND VALERATE INTO CELLULAR PLASMALOGEN BY BACTEROIDES SUCCINOGENES
Wegner, G. H. (University of Wisconsin, Madison) and E. M. Foster. Incorporation of isobutyrate and valerate into cellular plasmalogen by Bacteroides succinogenes. J. Bacteriol. 85:53–61. 1963.—Bacteroides succinogenes was found to require both a branched-chain volatile fatty acid (e.g., isobutyric) and a straight-chain acid (e.g., valeric) for growth. T

10. Use of modified norleucine-tyrosine broth in identification of Peptostreptococcus anaerobius.
Gas-liquid chromatography was employed to analyze the volatile and nonvolatile acids produced in modified norleucine-tyrosine (MNT) broth by various gram-positive cocci. The MNT broth consists of 0.5% Trypticase (BBL Microbiology Systems, Cockeysville, Md.), 0.5% yeast extract (Difco Laboratories, Detroit, Mich.), 0.2% L-norleucine, and 0.1% L-tyrosine. The

11. PROLINE OXIDASES IN HANSENULA SUBPELLICULOSA
Ling, Chung-Mei (Illinois Institute of Technology, Chicago), and L. R. Hedrick. Proline oxidases in Hansenula subpelliculosa. J. Bacteriol. 87:1462–1470. 1964—Cells of Hansenula subpelliculosa can use l-proline as a carbon and a nitrogen source after a 6- to 8-hr induction period. However, they cannot use l-glutamate as both nitrogen and carbon sources u

12. Lipid Metabolism of Rumen Ciliates and Bacteria: I. Uptake of Fatty Acids by Isotricha prostoma and Entodinium simplex
Washed suspensions of the ruminal ciliates, Isotricha prostoma and Entodinium simplex, concentrated C14-labeled oleic, palmitic, stearic, and linoleic acids within the cells during short incubation periods. Radioautographs demonstrated that oleic acid-1-C14 was hydrogenated to stearic acid by I. prostoma, and Warburg manometric data showed that the sodium sa
