To obtain microorganisms for the microbial conversion of ginsenosides in red ginseng extract (RGE), mushroom mycelia were used for the fermentation of RGE. After fermentation, total sugar contents and polyohenol contents of the RGEs fermented with various mushrooms were not a significant increase between RGE and the ferments. But uronic acid content was relatively higher in the fermented RGEs c...

BACKGROUND The expression and activity of the different Saccharomyces cerevisiae hexose uptake systems (Hxt) and the kinetics of glucose uptake are considered essential to industrial alcoholic fermentation performance. However, the dynamics of glucose uptake kinetics during the different stages of fermentation, depending on glucose and nitrogen availability, is very poorly characterized. The ob...

Consolidated bioprocessing (CBP) of cellulosic biomass is a promising source of ethanol. This process uses anaerobic bacteria, their own cellulolytic enzymes and fermentation pathways that convert the products of cellulose hydrolysis to ethanol in a single reactor. However, the engineering and economics of the process remain questionable. The ruminal fermentation is a very highly developed natu...

Abstract A novel wine has been developed from Camellia japonica ’s petal by fermenting the decoction with Saccharomyces cerevisiae or brewer’s yeast. pH, brix, specific gravity and alcohol percentage were tested to study physicochemical properties of wine. Qualitative tests indicated presence phenols such as flavonoids, coumarins; protein; glycosides; glycerin; terpenoids; steroids; fatty acids...

During alcoholic fermentation of must from dried grapes, yeasts are subjected to very high sugar concentrations, besides other environmental stresses, and they modify their metabolic behaviour giving low ethanol yield and abnormally high acetic acid production. To investigate the protective effect of catechin, inositol, and SO2 on wine yeasts, three thermotolerant strains of Saccharomyces cerev...

the use of stokes boundary values problems for the determination of the geoid requires that gravity anomalies (as boundary values) are known on geoid (as boundary). while, the gravity observations are measured on the earth's surface, to obtain boundary data, the surface gravity anomalies does are downward from the terrain onto geoid. for downward continuation (dwc) of surface gravity anoma...

Consumption of imported wines has been on the increase in Nigeria. This has further dwindled the foreign reserve. This necessitated this work to study some wine parameters of wine produced from mixed fruit juice of Mango and Pineapple. Wines are mostly produced from single fruit must. The wine produced from mixed fruit juices of Mango and Pineapple had a good quality. The total dissolved solid ...

The observable universe could be a 1 + 3-surface (the "brane") embedded in a 1 + 3 + d-dimensional spacetime (the "bulk"), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk. At least one of the d extra spatial dimensions could be very large relative to the Planck scale, which lowers the fundamental gravity scale, possibly even down to the ele...

the method of artificial neural network is used as a suitable tool for intelligent interpretation of gravity data in this paper. we have designed a hopfield neural network to estimate the gravity source depth. the designed network was tested by both synthetic and real data. as real data, this artificial neural network was used to estimate the depth of a qanat (an underground channel) located at...

Lignocellulose wastes are the most abundant residues on surface of earth. This project studies possibility ethanol production from a forestry waste. Wood Gmelina arborea were treated with dillute sulfuric acid to break down lignin component. Fermentation for was done using baker’s yeast (Saccharomyces cerevisiae ATCC 204508/S288c) 120 hours submerged fermentation, and pH, reducing sugar, specif...
