1. Metagenomic and metatranscriptomic analysis of the microbial community structure and metabolic potential of fermented soybean in Yunnan Province
Abstract Traditional fermented soybean contains a variety of microflora. To obtain a comprehensive and accurate understanding of the microbial community structure and metabolic potential of fermented soybean, comparative metagenomics and metatranscriptomics were performed on a sample of fermented soybean in Yunnan Province. Metagenomic DNA and metatranscript

3. The role of yeast culture (Saccharomyces cerevisiae) on performance, egg yolk fatty acid composition, and fecal microflora of laying hens
ABSTRACT This study investigated the effects of different levels (0.05, 0.1, and 0.2%) of yeast culture supplementation on body weight, feed intake, feed conversion ratio, egg production, egg weight, egg quality traits, egg yolk fatty acid composition, and microbiological flora in feces. A total of 240 laying hens at 18-19 weeks of age were divided into four

4. Performance of Nellore cattle fed individualy or in group, nutrient requirements and proteic evaluation of feeds for ruminants / Desempenho de bovinos Nelore alimentados individualmente ou em grupo, exigências nutricionais e avaliação protéica de alimentos para ruminantes
The present work was developed based on four experiments. The two firsts were conducted aiming to evaluate the fecal dry matter production using total fecal collection or estimated by chromic oxide (Cr2O3), titanium dioxide (TiO2), isolated, purified and enriched lignin of Eucalyptus grandis (LIPE), indigestible neutral and acid detergent fiber (NDFi and ADF

5. Analysis of diesel engine operation with biodiesel blends / Analise da operação de motores diesel com misturas parciais de biodiesel
As conseqüências da adição de biodiesel ao óleo diesel foram estudadas estabelecendo-se relações de causa e efeito entre o desempenho do motor e os processos de combustão e formação de mistura. Foram incluídos, nesta discussão, aspectos como emissões poluentes, formação de mistura, dinâmica do processo de combustão, eficiência de conversão

6. Suplementação com ionóforo à dieta de novilhas leiteiras em crescimento compensatório / Ionophore supplementation in the diet of dairy heifers in compensatory growth
The objective proposed for this study was to evaluate the compensatory growth regimes and the supplementation with ionophores to the diet on the performance, digestive parameters, metabolic profile and mammary gland development of dairy heifers. The experiment was carried out during the period of April to September of 2004. Twenty purebred heifers from the B

7. Uso de enzimas na alimentação de frangos de corte / Enzyme utilization in diets for broilers
Two experiments were done by Aviculture Department of Agronomy School of Federal University in Bahia in order to evaluate microbial enzymes effects over Ross broiler?s performance, by weight gain parameters, meal consume and feeding conversion. The first experiment was realized using 288 chicks with 8-21 days old, the experimental delineation used was comple

8. Microbial conversion of ethylbenzene to 1-phenethanol and acetophenone by Nocardia tartaricans ATCC 31190.
A culture of Nocardia tartaricans ATCC 31190 was capable of catalyzing the conversion of ethylbenzene to 1-phenethanol and acetophenone while growing in a shake flask culture with hexadecane as the source of carbon and energy. This subterminal oxidative reaction with ethylbenzene appears not to have been previously reported for Nocardia species. When N. tart

9. Assessment of Microbial Fouling in an Ocean Thermal Energy Conversion Experiment
A project to investigate biofouling, under conditions relevant to ocean thermal energy conversion heat exchangers, was conducted during July through September 1977 at a site about 13 km north of St. Croix (U.S. Virgin Islands). Seawater was drawn from a depth of 20 m, within the surface mixed layer, through aluminum pipes (2.6 m long, 2.5-cm internal diamete

10. Microbial and Physiological Characterization of Weakly Amylolytic but Fast-Growing Lactic Acid Bacteria: a Functional Role in Supporting Microbial Diversity in Pozol, a Mexican Fermented Maize Beverage
Pozol is an acid beverage obtained from the natural fermentation of nixtamal (heat- and alkali-treated maize) dough. The concentration of mono- and disaccharides from maize is reduced during nixtamalization, so that starch is the main carbohydrate available for lactic acid fermentation. In order to provide some basis to understand the role of amylolytic lact

11. Bacillus subtilis Metabolism and Energetics in Carbon-Limited and Excess-Carbon Chemostat Culture
The energetic efficiency of microbial growth is significantly reduced in cultures growing under glucose excess compared to cultures growing under glucose limitation, but the magnitude to which different energy-dissipating processes contribute to the reduced efficiency is currently not well understood. We introduce here a new concept for balancing the total c

12. Control of Interspecies Electron Flow during Anaerobic Digestion: Significance of Formate Transfer versus Hydrogen Transfer during Syntrophic Methanogenesis in Flocs
Microbial formate production and consumption during syntrophic conversion of ethanol or lactate to methane was examined in purified flocs and digestor contents obtained from a whey-processing digestor. Formate production by digestor contents or purified digestor flocs was dependent on CO2 and either ethanol or lactate but not H2 gas as an electron donor. Dur
