A yeast used for pizza and its production method are provided. The yeast is dry yeast, and the amount of CO2 produced in the dough at 30° C. during 60 minutes is 250˜450 mL CO2/h, wherein the dough contains those ingredients as following: 280 g flour, 1.43% salt by weigh of flour, 4 g pure dry yeast and appropriate content water. The production method includes the following steps: A) one-step fermenting; B) drying: in which, after the one-step fermenting without further fermenting; before or during the drying step, adding the emulsifier. Since adapting the first seed yeast as commercial yeast, the fermenter procedure is omitted, the process is simplified, the cost is reduced, and the yeast produced meets the property requirements of the yeast used for pizza.

The present invention provides a combination used for absorbing toxins in feed, comprising 1-10% by weight of clay and 90-99% by weight of yeast manna oligosaccharide, wherein the yeast manna oligosaccharide is extract of yeast cell wall which is separated from Saccharomyces cerevisiae. The biotoxin sorbent product can be used to feed any animals, including livestock, fowls, marine lives and ruminants. When mixing with feed, owing to its strong toxin adsorption capability, this absorbent may reduce the amount of toxins entering bodies of animals, thereby improving productivity and health of animals, reducing diseases caused by toxins.

The present invention relates to a composite yeast suitable for high concentration alcohol fermentation from sugar-containing raw materials, characterizing in that the composite yeast comprises any kind of dried yeast selected from Brewers yeast Saccharomyces cerevisiae Hansen of Saccharomyces cerevisiae, grape wine yeast Saccharomyces uvarum Beijerinek, and nutritious materials which are necessary for yeast growth, the nutritious materials include: the dried yeast 40-70 parts by weight, a nitrogen source 20-40 parts by weight, a phosphorous source 5-10 parts by weight, an other inorganic salt 2.5-5 parts by weight, a trace vitamin 1-2.5 parts by weight and a bacteriostatic 0.5-1.2 parts by weight. The present invention further relates to a method for preparation of the composite yeast suitable for high concentration alcohol fermentation from sugar-containing raw materials. Using the composite yeast of the present invention to proceed with sugar fermentation can increase fermentation alcoholicity, decrease residual sugar content, and allows the final alcoholicity of standard raw material, such as sucrose to attain to 14.5-15.5% v/v, and the amount of the residual reducing sugar in the fermentation mash is 0-0.1 wt %.
摘要:
A method for producing cellulosic ethanol is disclosed, which comprises the following steps: adding the medium containing the source materials of cellulose and/or hemicellulose to fermentation reaction vessel; adding cellulase to fermentation reaction vessel, and inoculating Candida lusitaniae; running simultaneous saccharification fermentation (SSFs) with the combined action of cellulose and Candida lusitaniae, and obtaining cellulosic ethanol by separation. Candida lusitaniae used in SSFs in present invention has higher ethanol tolerance and a higher ethanol production rate, it can use cellulose and hemicellulose as source materials and effectively produce cellulosic ethanol with cellulase in SSFs.
摘要:
The present invention relates to a composite yeast for high concentration alcohol fermentation, which includes thermostable Saccharomyces cerevisiae, acid protease, phytase, cellulose, β-glucanase, and pectinase, and is suitable for the high concentration alcohol fermentation for various raw materials. In addition to normal fermentation, the composite yeast of the present invention can degrade the raw materials, increase the nutrient ingredients in the mash, promote the growth of yeast and provide stress tolerance protection.

摘要:
The present invention provides a method for extracting glucan and mannan from the cell wall of a microorganism. Specifically, the method of the present invention in one embodiment comprises the steps of: a) treating the cells of the microorganism with an alkaline protease and an mannanase; b) separating the mixture from step a) into a heavy phase and a light phase; c) drying the heavy phase obtained from step b), obtaining the glucan preparation; and d) drying the light phase obtained from step b), obtaining the mannan preparation. Optionally, in the step c), the heavy phase obtained from step b) may be treated sequentially with an alkali and an acid, and separated again into a heavy phase and a light phase. The heavy phase is dried, obtaining the glucan preparation. The present invention further relates to the glucan preparation and mannan preparation produced thereby, and the uses thereof.
摘要:
A method for processing a lignocellulose material, comprises the following steps: (1) crushing and sieving the lignocellulose material, and collecting granules with a particle size of between 0.08 and 0.1 mm; (2) mixing the granules obtained in step (1) with water, and dispersing through a colloid mill to yield a suspension with a particle size of 40-80 μm; (3) homogenizing the suspension obtained in the step (2) under high pressure to have a particle size of between 10 and 40 μm; and (4) buffering the suspension obtained in the step (3) with a buffer solution of sodium acetate and acetic-acid, adding cellulase, β-glucosidase, and xylanase, and performing zymolysis for 36-72 hours.
