The aim of this study was to investigate the effect of bacterial inoculation on the fermentation and aerobic stability of corn silage and on the dry matter degradability and milk composition when fed to sheep or cows. Four male sheep were selected to measure dry matter degradability of uninoculated (UCS) and inoculated (ICS) corn silage. Milk composition was measured for 22 Holstein cows, separ...

This experiment investigated the effect of intraruminal infusion of propionic acid on the net flux of nitrogenous compounds across the mesenteric- (MDV) and portal-(PDV) drained viscera of seven Friesian steers, average BW 127 kg (SEM 4.6), fed a grass-pellet diet. Each received by random allocation 0 (control), .5, or 1.0 mol of propionic acid/d for 7 d. Blood flow in mesenteric and portal vei...

An analytical technique was developed for the quantitation of volatile organic compounds (VOC) in three different forms of electronic cigarette (EC): solution, vapor, and aerosol. Through the application of the mass change tracking (MCT) approach, the consumed amount of the solution was measured to track the conversion of targets between the different phases. The concentration of aerosol plus v...

A simple gas-liquid chromatographic procedure for analyzing ethanol, acetic acid, acetoin, and racemic and meso-2,3-butylene glycol in broth media is described. Overnight broth cultures were filtered or centrifuged, and the filtrate or supernatant was treated with formic acid to aid separation of volatile fatty acids. Samples were then directly analyzed by gas-liquid chromatography on a 20% Twe...

Abstract Plant endophytic microorganisms, which can enhance plant growth and resistance to biotic abiotic stresses, are untapped resources with large potential applications for crop production. However, the community is influenced by multiple factors, such as host genetics, environment, other microbes. Thus, it important characterize well-adapted endophytes from native crops. We isolated 43 bac...

in this research, the accelerated ripening of the kabkab dates from khalal to tamr using nacl and acetic acid solutions was studied. fruits at khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. nacl solutions, 2. acetic acid solutions and 3. aqueous solution of nacl (1%) and acetic acid. moisture, ph, colour, brix and textural firmness of...

Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...

Propionibacteria have been reported as being oxygen sensitive bacteria. Nevertheless, in this work, we intend to show that Propionibacterium shermanii CDB 10014 is able to grow even at high volumetric oxygen transfer coefficients (KLa). Similar final cell concentrations were achieved in experiments at different KLa values, with increasing cell yield from 0.08 g/g cells in anaerobic con­ ditions...

Background: Probiotics are live microorganisms which that provide various health benefits to the host upon administration in adequate amounts. Lactobacilli, Propionibacterium, and Bifidobacterium common “Lactic Acid-producing bacteria (LAB)” present probiotic formulations. These release many organic acids, mainly lactic acid, acetic propionic acid into their surrounding environment. Increased c...

The accumulation of volatile fatty acids (VFAs) through the anaerobic fermentation organic waste, such as strawberry extrudate, is proposed for this work. A hydrothermal treatment was carried out, and it to break complex matrix extrudate favour hydrolysis stage digestion process. production from treated untreated evaluated by adjusting pH 5 9. After an increase in solubilisation matter, sugars ...
