Selenium (Se) enriched yeast, produced by growing of Saccharomyces cerevisiae in Se rich media, is a recognized source of organic food-form of Se. Effects of culture conditions (temperature, fermentation time, initial pH value, shaking speed, as well as time and concentration of Se added to medium) on the bioaccumulation of Se in yeast were investigated by Plackett-Burman design in this paper. ...

The volatile organic compounds (VOCs) formed during winemaking can be modulated by several additives, namely the use of sulphur dioxide (SO 2 ) which has been well-accepted on as a preservative agent. However, some drawbacks associated with SO wine application led to need reduce or replace its use. In this work, VOCs profile after storage in bottle under different antioxidant conditions two Por...

Assessment of the diet adaptation period is critical for feeding experiments in ruminants to have significant changes concerned parameters. An vitro trial was conducted investigate impact sampling at different time periods (day 0, 11, 21, and 60) determine feed treatment over ruminal fermentation parameters crossbred Karan-Fries cattle (Bos taurus) Murrah (Bubalus bubalis) heifers. Two types to...

This work evaluated the effect of cocoa pulp as a malt adjunct on the parameters of fermentation for beer production on a pilot scale. For this purpose, yeast isolated from the spontaneous fermentation of cachaça (SC52), belonging to the strain bank of the State University of Feira de Santana-Ba (Brazil), and a commercial strain of ale yeast (Safale S-04 Belgium) were used. The beer produced wa...

The Japanese fermented food Natto contains menaquinone 7 (MK7), which is known to increase bone mineral density and reduce bone fractures. Natto is traditionally produced via the solid state fermentation of soy beans by Bacillus subtilis natto. The aim of this study was to investigate the effects of static and dynamic solid state fermentation (SSF) on the production of MK7 using polenta (milled...

Fifty-four roughages of known voluntary dry-matter intakes (DMI; range 7.8-35.2 g/kg live weight per d) were examined in vitro in a gas production test. Samples (200 mg) of roughage and roughage neutral-detergent fibre (NDF) respectively were incubated in a mixed suspension of rumen contents for 96 h and the gas volumes recorded after 4, 6, 8, 12, 24, 30, 36, 48, 54, 60 and 96 h. The kinetics o...

Among the various fungal strains screened for citric acid production, Aspergillus niger is known to produce considerable amounts of citric acid and other organic acids when cultivated in carbohydrate-rich medium of fermentation. A number of indigenous raw materials such as cane molasses and pumpkin have been carried out in present study for citric acid production by using gamma ray induced muta...
