Abstract
The utility model relates to a system for extracting cellulose from straw stalks and producing biological feeds. A straw pre-processing device is connected with a cellulose fermenting device by a fodder conveying belt; the cellulose fermenting device is connected with an enzyme solution separating device by the fermented material conveying belt; and the enzyme solution separating device is connected with a biological feed production device by an enzyme solution conveying pipeline. By adopting the biological technology, the cellulose is manufactured and added in plant raw materials such as straws, corn stalks, durra straws and the like in a convenient way so as to decompose the fiber, thus forming a novel farming and forestry chain which takes xylo-oligosaccharide as a core, highly utilizes agricultural and forestry wastes, and has green cultivation and safe animal food production. The straw biological feed fermented by utilizing the cellulase and hementerin has good palatability and high nutritional value, can improve the productivity of domestic animals by more than 4%-6%, reduces the use amount of antibiotics by more than 50%, and improving the cultivating and income increasing benefits by 18%-25%.
Description
Technical field:
The utility model belongs to agricultural biotechnologies, and process technology and preparation production system by autonomous innovation extract cellulase, and be used in the production of biological feedstuff from straw.
Background technology:
In agricultural production, a large amount of straw and the stalk of other crop do not obtain utilizing, and as discarded object, have wasted resource and polluted environment again.Partly be used for herding and feed, but digestibility is not high, its main cause is that a large amount of fibers fails to obtain to transform.Adopt biotechnology, in easy mode, making cellulase makes an addition in straw or other stalk, decompose fiber, can significantly improve culture benefit, thereby forming one is the green cultivation of agriculture and forestry organic waste material high-value-use of core and the novel farming and animal husbandry industrial chain that safe animal foodstuff is produced with the xylo-oligosaccharide, utilize the plain fermented stalk biological feedstuff of cellulase and multi-functional fibrinolytic, can improve more than the breeding performonce fo animals 4%-6%, reduce antibiotic dosage more than 50%, improve and culture the benefit that increases income 18%-25%.
Cellulase extensively is present in the natural organism, can both produce cellulase in the bacterium, fungi, animal body etc.; The cellulase that generally is used to produce comes from fungi, more typically has wooden enzyme genus, inulinase to belong to and Penicillium.
The a lot of fungies of occurring in nature can both the plain enzyme of eccrine fiber.Have high synergistic enzyme and form by many, can be divided into three classes: 1. exoglucanase C
12. endoglucanase Cx; 3. beta-glucosidase β G.
1), C
1Enzyme: this is the enzyme that cellulose is worked at first, and it destroys the crystalline texture of cellulose chain, plays hydration.Be C
1Enzyme is to act on the insoluble fibrin surface, uses avicel cellulose chain cracking, and the long chain cellulose molecular end is partly free, thereby makes cellulose chain be easy to aquation.
2), C
XEnzyme: effect C
1The cellulose of enzyme activation, the cellulase of decomposition β-1,4 chain.Mainly comprise inscribe-1,4-1,4 beta-glucanase and circumscribed-1,4-1,4 beta-glucanase.The former cuts β-1,4 chain from the inner optional position of high molecular polymer, mainly generates cellobiose, cellotriose etc., and the latter acts on low-molecular polysaccharide, from the non reducing end glucose that dissociates.
3), β G enzyme: be cellobiose, cellotriose and low molecule cellodextrin thereof are decomposed into glucose.
Above-mentioned three kinds of cellulases are when decomposition of cellulose, and any enzyme all can not cracking crystal fibre element, have only that three kinds of enzymes are common to be existed and during synergy, just can finish hydrolytic process.
Multi-functional fibrinolytic element is a natural composition matter of extracting effective ingredient from fly maggot, earthworm, spiral shell, pluck, contains abundant enzyme, polypeptide composition, the plain additive of the chemically grown in the alternative feed in the past, chemobiotic medicine.
Cellulase is used in combination with multi-functional fibrinolytic element in fermentation rice straw manufacturing biological feedstuff; reduced cost of material; the energy and the palatability of product have also been improved simultaneously; the application of microorganism beneficial bacterium and multi-functional fibrinolytic element is instead of chemical auxin additive, antibiotic medicine not only, and has improved foodsafety and environmental protection function.
Custom-designed technology and production preparation system can be made cellulase at an easy rate, and be directly used in the production biological feedstuff.
