Abstract:

This research has developed a new method of fermentation of set yoghurts made from buffalo's milk using ultrasound technology. It investigated the effects of power ultrasound on the starter culture members which are used to ferment buffalo's milk. The study determined the changes that take in the components of buffalo's milk due to the ultrasound. The results were used to determine the optimum process conditions for the fermentation of buffalo's milk. Outcomes of the research will lead to higher productivity and better quality set yoghurts manufacturing.

Abstract:

The Virginia cider industry has grown rapidly in the past decade, and demands research-based recommendations for cider fermentation. This study evaluated relationships between the unique chemistry of apples and production of hydrogen sulfide (H2S) in cider fermentations. Yeast assimilable nitrogen (YAN) concentration and composition and residual fungicides influence H2S production by yeast during fermentation, but these factors have to date only been studied in wine grape fermentations. This study surveyed 12 Virginia-grown apple cultivars and found that the majority were severely deficient in

The forages used in the first experiment were lucerne hay (LH), oat hay (OH) and wheat straw (WS). The same forages were used in the second experiment, but they were mixed with a concentrate feed to make three mixtures consisting of 80% (HC), 50% (MC) or 20% (LC) concentrate. The ex

Thesis (MScAgric (Animal Sciences))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: Ruminants have a compound stomach system that enables them to utilize forages more efficiently than monogastric animals. However, forages alone do not contain sufficient nutrients to meet the requirements of high producing dairy cows. Forages are high in fibre and their nutrient availability depends on the degree of cell wall degradability. Improvements in forage fermentation would increase energy intake and subsequently milk production and performance by dairy cows. It is therefore important to fin

Biofuels produced from lignocellulosic biomass via the fermentation platform are sustainable energy alternatives to fossil fuels. Process Systems Engineering (PSE) uses computer-based tools and methods to design, simulate and optimize processes.

Total tract digestion coefficients for dry matter (DM) and neutral detergent fiber (NDF), passage rates for grain and roughage components of diets and liquid turnover were measured for 65 and 90% concentrate diets in separate 4 x 4 Latin square experiments using intact growing steers. Kinetics of in situ digestion for DM and NDF in diet ingredients, rumen pH, volume and DM distribution were determined in mature, rumen cannulated steers. Rates of passage and digestion were combined to calculate apparent extent of ruminal digestion (AERD) for diet ingredients. Diets were based on steam flaked mi

Abstract:

Les procédés de fabrication de produits carnés stables à température ambiante s'articulent autour de la théorie des barrières et du couplage d'opérations unitaires telles que le salage, le séchage, la fermentation, le fumage. Dans les pays du Nord, ces procédés traditionnels ou industrialisés, aboutissent à des produits finis à la fois stables à température ambiante et prêts-à-consommer. Pour contrecarrer l'altération de la viande, accrue en conditions tropicales ou en conditions d'hygiène non maîtrisées, les procédés traditionnels du Sud mettent en œuvre des traitements plus drastiques et abo

Abstract:

Nos últimos anos, duas tendências tem se destacado no universo cervejeiro: a obtenção de cervejas a partir de mostos concentrados e a elaboração de cervejas utilizando adjuntos especiais, os quais podem aromatizar ou não as mesmas. Visando um aumento da produtividade juntamente com uma menor necessidade de investimentos na capacidade produtiva, algumas cervejarias vêm optando pelo aumento do extrato inicial de fermentação para valores superiores aos tradicionais (10-15 0P). A elaboração de cervejas utilizando adjuntos especiais vem se tornando uma solução de barateamento na obtenção de cerveja

As bactérias ácido-láticas (BAL) são micro-organismos que auxiliam nas características organolépticas, funcionais e de bioconservação de produtos fermentados. A utilização do soro de leite como meio de cultivo natural enaltece o conceito da produção de biomoléculas de alto valor agregado, como bacteriocinas, já que é um subproduto gerado por indústrias de laticínios e considerado um agente poluidor. A inulina é um ingrediente prebiótico que promove seletivamente o crescimento de culturas probióticas. Nesse âmbito, o objetivo deste estudo foi avaliar o efeito da composição da cultura de Lactoco

Ce travail de thèse concerne la valorisation des pommes libanaises en évaluant leur potentiel fermentaire en vue de l’élaboration du cidre, spécifiquement l’étape de la fermentation de ce processus. Pour cette fin, l’analyse de la composition chimique des pommes libanaises « Ace spur » a été effectué en comparaison avec une pomme à cidre « Kermerrien » utilisée industriellement en France pour la production du cidre. La variété de pomme libanaise « Ace spur » semble être convenable pour l’élaboration de cidre. De plus, une souche responsable de la fermentation spontanée de cette variété de pomm

Abstract:

Fossil fuel is an important energy source, but is unavoidabiy running out. Since the cellulosic material is the most abundant source of organic matter, the ethanol, which is produced from cellulosic waste materials, is gaining more and more attention. These materials are cheap, renewable and their availability makes them superior compared to other raw materials. The cellulose must be hydrolyzed to glucose before it can be fermented to ethanol. The enzymatic hydrolysis of cellulose using cellulase enzymes is the most widely used method. The production cost of cellulase enzymes is the major cost

Abstract:

Ethanol production through biomass fermentation is one of the major technologies available to produce liquid fuel from renewable energy sources. A major problem associated with the production of ethanol through fermentation remains the inhibition of the yeast Saccharomyces cerevisiae by the produced ethanol. Currently high water dilution rates are used to keep the ethanol concentrations in the fermentation broth at low concentrations, resulting in low yields and increased downstream processing to remove the excess water. Yeast strains that have a high tolerance for ethanol have been isolated b

Neste trabalho foi avaliada a possibilidade do emprego de caldo de cana-de-açúcar (Saccharum officinarum) como matéria-prima para obtenção de 2,3-butanodiol por fermentação, utilizando a bactéria Klebsiella pneumoniae NRRL B199. A pesquisa compreendeu o teste de diferentes nutrientes para a composição de um meio de fermentação eficiente com o caldo de cana e experimentos em que a influência da concentração inicial de sacarose (S0) sobre o processo em regime descontínuo foi estudada. Ensaios realizados em frascos agitados, com S0 entre 140 e 150 g/L, mostraram que a fermentação de caldo de cana
