A method of and system for making at least four types of animal feed products for various types of animals to maximize and use all of the components found in the whole stillage in an alcohol producing plant. The method includes liquefying, fermenting, distilling, performing a selective particle size separating into three streams, wherein the three streams contain a first stream of a large particle stream that is used to form a first animal feed suitable for ruminant animals, a second stream of a coarse protein stream that is used to form a second animal feed suitable for chicken and pigs, and a third stream of a fine particle stream that is used to form a third animal feed suitable for fish and pet. The third stream is further concentrated and enriched to have a syrup with 35%-80% of dry solid.

The invention discloses a method for improving ethyl alcohol production efficiency through INO2 gene overexpression, and belongs to the technical field of biological energy development. According to the method, an engineering strain obtained by performing INO2 overexpression in a strain with single ino4 gene deletion is applied to fermentation production of ethyl alcohol; compared with a wild no-load contrast strain, when fermentation is performed for 52 h, the biomass is increased by 186.6%, the ethyl alcohol yield is increased by 204.1%, and the ethyl alcohol-thallus yield is increased by 5.6%. Thus, the method has great industrial application value and broad industrial application prospects, and meanwhile important information is provided for constructing excellent saccharomyces cerevisiae genetic engineering strains capable of achieving a high ethyl alcohol yield.

The invention relates to a composite red date wine which is prepared from the following components in parts by weight: 10-30 parts of Neihuang date, 50-70 parts of Xinjiang date and 10-30 parts of Xinzheng golden-silk jujube. The preparation method comprises the following steps: compounding different species of red dates according to respective advantages, carrying out vapor explosion pretreatment on the red date raw materials, pulping with water, adding liquid koji into the date pulp, and directly fermenting. No enucleation, peeling or pectinase is needed in the preparation process. After the distillation, aging and storage are performed to prepare the wine. The composite red date wine has the advantages of plump wine body, thick date flavor, no foreign flavor, low methanol content and high polyphenol content.

The invention discloses a lemon distilled wine Saccharomyces cerevisiae lemon 2.1709, which is preserved in the General Microorganism Center of the China Microbiological Culture Collection Management Committee, and the preservation registration number is CGMCC No.15455. Also disclosed is a Saccharomyces cerevisiae preparation whose active ingredient is Lime 2.1709. Also disclosed is the application of Lime 2.1709 in brewing. Also disclosed is a method for preparing lemon distilled wine: 1) crush peeled lemons, and sterilize the obtained lemon crushed liquid; 2) inoculate the Saccharomyces cerevisiae Lime 2.1709 in claim 1 into the lemon crushed liquid in step 1), Stir evenly; 3) Ferment the lemon crushed liquid in step 2): keep it at 26-30°C for 13-17 days to ferment to obtain a fermented liquid; 4) filter the fermented liquid obtained in step 3); 4) The obtained fermentation filtrate is distilled to obtain lemon distilled wine.

The present invention discloses a method for increasing the alcohol fermentation yield through a Trichoderma viride fermentation extract. The method at least comprises: (1) adopting straws as a raw material to carry out solid state fermentation, wherein straw powder is added to a fermentation barrel, water and ammonium nitrate are added, complete stirring is performed, Trichoderma viride CGMCC3.6619 is inoculated to make the strain and the straw powder completely contact, continuous culturing is performed for one month, and drying is performed after completing the fermentation to obtain a fermentation matrix for spare; (2) carrying out extraction and purification on the extract alcohol fermentation auxiliary agent, wherein the fermentation matrix is soaked with a NaOH solution, constant temperature treatment and filtration are performed, the filtrate is concentrated to prepare a raw liquid, the pH value of the raw liquid is adjusted to 2.0, standing, centrifugation and precipitate removing are performed, and the supernatant is subjected to spray drying to a product alcohol fermentation auxiliary agent; and (3) carrying out alcohol fermentation, starch is taken and added to clear water, stirring is performed to make the starch be uniformly dispersed in the water, liquid high-temperature amylase and calcium chloride are added, the pH value is adjusted, liquid glucoamylase is added, cooling is performed after completing the saccharification, activated yeast and the alcohol fermentation auxiliary agent are added, and fermentation is performed in a constant temperature chamber.

The invention discloses a saccharomyces cerevisiae engineered strain expressing pectin esterase and application of the strain and belongs to the field of fermentation engineering. The saccharomyces cerevisiae engineered strain is characterized in that the encoding genes of the pectin esterase are fused with the encoding genes of alpha-lectin and then converted into saccharomyces cerevisiae, recombinant plasmids are integrated to the chromosome NDA of hosts to obtain the strain expressing the pectin esterase on the surfaces of cells in an anchored manner, and pectin esterase activity can reach 2.6U / g. When the strain is used for the alcohol fermentation production of raw materials such as sweet potatoes and cassavas, alcohol fermentation efficiency can be increased while fermentation liquor viscosity during fermentation can be evidently lowered, enzymatic action and saccharomyces cerevisiae metabolism are benefited, equipment burden can be lowered, and energy consumption can be reduced.
