摘要:
Use of an aqueous bio-catalytic composition in the manufacture of paper, the aqueous bio-catalytic composition comprising a fermentation supernatant, which comprises micronutrients, from a yeast culture containing no active enzymes, and one or more nonionic surfactants, wherein the bio-catalytic composition lacks any active enzymes, and wherein the yeast culture is a Saccharomyces cerevisiae culture. The use of the bio-catalytic composition prevents biological film growth and paper spotting, and substantially reduces starch build-up in the manufacture of paper.

The present invention relates to a yeast cell, in particular a recombinant yeast cell, the cell lacking enzymatic activity needed for the NADH-dependent glycerol synthesis or the cell having a reduced enzymatic activity with respect to the NADH-dependent glycerol synthesis compared to its corresponding wild-type yeast cell, the cell comprising one or more heterologous nucleic acid sequences encoding an NAD + -dependent acetylating acetaldehyde dehydrogenase (EC 1.2.1.10) activity. The invention further relates to the use of a cell according to the invention in the preparation of ethanol.
摘要:
The present invention relates to processes of producing a fermentation product from readily fermentable sugar-material in a fermentation vat comprising a fermentation medium, comprising: feeding the readily fermentable sugar-material into the fermentation vat comprising a slurry of fermenting organism; fermenting the readily fermentable sugar material into a desired fermentation product, wherein S8A protease is added during or after feeding of the readily fermentable sugar-material into fermentation vat or during fermentation of the readily fermentable sugar-material into the desired fermentation product. The invention also related to the use of S8A protease for reducing foaming in the fermentation wells generating by the fermenting organism during fermentation of the readily fermentable sugar-material.

Disclosed is a solid state biological reaction device, comprising a main tank (1), wherein the device further comprises a support (2) supporting the main tank (1), and the support (2) makes the main tank (1) be rotational in the horizontal position, and be statically cultured in the vertical position. The device is relatively simple, in particular, the mixing of materials uses the method of a vehicle-tank in combination with rotation, achieving the tank free conversion between the two different poses of vertical and the horizontal; and the device conducts the work of loading, inoculation, cultivation and transplantation and so on in the upright pose, and completes the work of sterilization and mixing of materials and so on in the horizontal pose. The device is not only quick to use and easy to move, but also omits the stirring system which occupies a lot of manufacturing costs, and is easy to use in large-scale production.

Provided is a method for producing a yeast containing glutamic acid at a high concentration. In the method for culturing a yeast, a yeast in a stationary growth phase is subjected to liquid culture under the conditions that the pH of a liquid medium is 7.5 or higher and lower than 11. After the pH of the liquid medium for the yeast in a stationary growth phase is adjusted to 7.5 or higher and lower than 11, the yeast is further cultured, whereby a yeast with a high glutamic acid content can be produced. In the invention, as the yeast, Saccharomyces cerevisiae or Candida utilis can be used. Therefore, by using the yeast with a high glutamic acid content obtained by the above-said method and the extract obtained by extraction from the yeast, a seasoning composition and a food or drink with a high glutamic acid content can be provided.
摘要:
The present invention relates to a novel form of compressed yeast for direct inoculation in the fermentation of a fruit or vegetable substrate, e.g. for the fermentation of beverages, such as wine or beer. Especially, the present invention relates to compressed yeast with a dry matter content of between 35% and 90% (w/w), preferably in a frozen form, a method for producing a fermented beverage by direct inoculation of a fruit or vegetable substrate with the compressed yeast and a container comprising the compressed yeast.

This invention is a method for improving production yield of HPV L1 protein including the step of culturing a cell expressing HPV L1 protein in a medium containing a high concentration of carbon source. According to the culture method of this invention, by using a medium containing a high concentration of carbon source, the production yield of HPV L1 protein can not only be remarkably increased but also the immunogenicity of the produced HPV L1 protein is significantly increased.
