Lus), Penicillium (Penicillium), Sporotrichum (Sporotrichum), Sclerotinia (Sclerotinia) etc., polygalacturonase generally forms through these bacterial classification liquid submerged fermentations are refining.Described cellulase also is to obtain with strain fermentation, the microorganism that is used for the production of cellulose enzyme is also more, wherein the bacterial classification that enzyme activity is stronger is a wood mould (Trichodermasp), whiterot fungi (Panus conchatu.), aspergillus (Aspergillus sp.), head mold (Rhizopus) and Penicillium (Penicillium), with Trichodermareesei (Trichoderma reesei Rut C-30), viride (TrichodermavirideAS3.3032), koning trichoderma (Trichoderma Koningii), crassas (Neurospora sp.) etc. are the typical case the most, it is the bacterium of cellulase production preferably of generally acknowledging at present, and made preparation, the document introduction is arranged, black-koji mould (Aspergilusniger, AN) has the effect of producing polygalacturonase and cellulase simultaneously, so can be with black-koji mould (Aspergilus niger, AN), obtain being fit to the bacterial classification of various starch through domestication.But if these bacterial classifications without domestication, just can not be survived in starch liquid, and nutrition also is unfavorable for growth inadequately, more can not talk about the effect of coordinating distillery yeast.
The bacterial classification that produces polygalacturonase and cellulase generally will add substratum earlier to carry out enlarged culturing 1-2 days in 25-35 ℃ greenhouse, substratum adopts starch+peptone+sucrose or dextrose culture-medium commonly used in the document, general 1 liter of substratum starch accounts for the 20-30 gram, peptone accounts for the 20-30 gram, sucrose or glucose 20-30 gram, sodium-chlor 5-10 gram, adding distilled water makes it reach 1 liter, cultivating the back adding tamed 1 day according to the yellow seriflux of fermentation concentration again, (temperature and fermentation jar temperature are basic identical), the growing state of observing that group bacterial classification of that class preferably just preferably comes out, bacterial classification and enzyme liquid with domestication is filled into carrier together and is placed in the tank body then, so just can produce.
The present invention was introduced into yellow seriflux the bioenzyme activity catalyst-assembly before this before the alcohol amylofermentation, flow through behind the bioenzyme activity promotor carrier, make yellow seriflux fully contact with promotor with active biological enzyme, the complete decompose pectin of active biological enzyme after 30-60 minute, part is decomposed hemicellulose and Mierocrystalline cellulose, makes it to change into five-carbon sugar and hexose.Active biological enzyme suppresses assorted bacterium by biological enzyme and hydrolysis acid solution and generates along with material enters saccharification, the continuation effect of fermentation workshop section; Promotor enters yeast cell nuclear and activates saccharomycetic physiologically active, and metabolism improves fermentation efficiency, improves the ethanol production effect thereby reach.
Technical characterstic of the present invention is: because of not needing to increase starting material, need not increase power and steam, so come any operation negative pressure for the original production tape; Present technique can be eliminated pectin and the assorted bacterium that is unfavorable for yeasting, and starch effectively is converted into sugar, improves fermentation efficiency, effectively improves ethanol production.Therefore, use present technique not only economy but also practicality.
The principle that technical scheme of the present invention is achieved is: by polygalacturonase, the biological activity promoters that cellulase and trace element are formed is placed to the front of fermentor tank with carrier, making starchy material be in contact with it the back improves active, be swift in response, create the yeast fermentation good environment, though the document of prior art is also mentioned polygalacturonase, cellulase can improve the yield of liquor and the utilization ratio of raw materials of alcohol, reduce the viscosity of feed liquid, shorten fermentation time, but owing to do not adopt immobilized form, do not add trace element in the material yet, reaction process is discontinuous, and effect is remarkable inadequately.So gordian technique of the present invention is under the effect of biological enzyme, micro-compound active catalyst, can destroy colloid in the cassava mash, part decomposition of cellulose and hemicellulose, promote Mierocrystalline cellulose, hemicellulose to decompose, the synergy of enzyme suppresses varied bacteria growing during the fermentation, realize creating good yeasting and yeast and utilize substrate, improve ethanol production.
Since the test of Pingguo, Guangxi grain distillery, small test moved for some time, produces the alcohol rate and improved 5% to 15% on former basis from the yellow Rong Sheng of contriver in 2000 in the present invention.
21 century is the fiercest century of energy contention, and countries in the world all tap a new source of energy when grabbing the existing energy energetically.Therefore develop a kind of new wide material sources, the cheap energy has been very urgent.The U.S. just has realized that the advantage of alcohol fuel as far back as eighties of last century, forces to add 10% alcohol in fuel, and has added 22% in Brazil.Project on China Jilin, Henan, Anhui and other places with the alternative gasoline of alcohol alcohol has also had much effect; 2008 Beijing Olympic, Beijing Municipal Government also promised to undertake city public transport and taxi use instead alcohol as clean fuel to reduce atmospheric pollution.And grain resource is also more and more in short supply, and in this case technology of the present invention being used to produce alcohol is matters vital to national well-being and the people's livelihood, and prospect is boundless.So after the present invention is widely used in the factory of starch Alcohol Production, under the situation of flow process that does not change the original production line and equipment, can improve ethanol production greatly, for transport trade provides more multipotency source.
