Description
Technical field
The invention belongs to field of fodder, relate to a kind of aspergillus versicolor of the little seeds of a tung oil tree grouts toxic composition of degrading.
Background technology
In short supply day by day along with petroleum resources greatly developed biomass energy and is the inevitable strategic choice that China improves energy security, ensures power supply.The little seeds of a tung oil tree (
Jatropha curcasL. have another name called the cream paulownia, Cortex jatrophae etc.) belong to Euphorbiaceae leprosy Pterostyrax, be considered to develop the suitable seeds of biofuel, but its industrial development also is in commitment, there are problems such as cost is higher, by product can't make full use of.
Along with rapid development of economy, China has become maximum in the world aquaculture country.Protein raw material is the basis of feed industrial development, and the in short supply and price of protein raw material is surging to have become and will become for a long time China's one of bottleneck with water industry of developing animal husbandry.
After little seeds of a tung oil tree grouts are taken off grease; Protein contnt reaches 68% sometimes up to more than 50%, and all is true albumen more than 90%; Except that Methionin, the content of other primary amino acid all is higher than the diet solids content standard that the World Food Programme (FAO) is children's formulation in 5 years old.The nutritive value of little seeds of a tung oil tree grouts is higher than the protein content of 35-50% such as dregs of beans commonly used in the feed, rapeseed meal.The coarse-fibred content of little seeds of a tung oil tree cake is lower than 18% of roughage index about 3%.Jatropha curcas oil dregs of rice external digestion rate reaches 86% at 78.6-80.6% after the thermal treatment.It is thus clear that little seeds of a tung oil tree grouts are a kind of very potential protein feed resources.But, containing more toxicant in the little seeds of a tung oil tree cake, can not directly use as feed.The little seeds of a tung oil tree cake of interpolation 16% can produce obvious toxic and side effects to mouse in feed.Even so-called nontoxic little seeds of a tung oil tree kind also has certain toxicity, just toxicity is low slightly.At present, still do not have and well remove the toxic method of little seeds of a tung oil tree grouts.If with behind the little seeds of a tung oil tree cake detoxifying as protein fodder, not only can alleviate the nervous situation of China feed protein resource, can also reduce little seeds of a tung oil tree biofuel cost significantly, help the industrialization of little seeds of a tung oil tree biofuel.The technology of the little seeds of a tung oil tree cake of exploitation ability effective elimination toxic component has important economic value.
The little seeds of a tung oil tree cake detoxifying method of having reported has: chemical process like the alkaline purification method, promptly adds NaOH, Ca (OH) in grouts
2Or NaOCl; Physical method is like heat treating process, radiation exposure and organic solvent elution method.But heat treating process can not remove toxicity, even also can increase toxicity.Alkaline purification method effect is limited, and can produce the intensive smell after the alkaline purification, destroys nutritive ingredient, the animal food refusal, and cause environmental pollution.The solvent-extraction process cost is expensive, also can residual intensive smell, influence palatability and the contaminate environment of animal.The radiation exposure poor.
Be developed to aspect the feed at little seeds of a tung oil tree cake, people such as Yuan Xiao have applied for " a kind of fish meal and preparation method (200710053524.7) with Jatropha curcas L dregs ", disclosure of the Invention the method for a kind of little seeds of a tung oil tree cake detoxification, with 7 times of little seeds of a tung oil tree grouts of methanol wash.People such as Liu Qiang have applied for " method (201110003750.0) of a kind of little seeds of a tung oil tree and cake detoxifying thereof ", and its poison-removing method is first with normal hexane lixiviate grease, and the extraction using alcohol toxic component is used in the back then, and the alcohol extracting dregs of rice are fried precipitation with steam, obtain the detoxification Jatropha curcas L dregs.People such as king main forces have also applied for " a kind of method of abstracting and removing phorbol ester from barbadosnut seed oil meal (200810201109.6) ", also are to remove Buddhist ripple ester with methanol extraction.People such as Zhang Hui have applied for " method (201010520744.8) of detoxification of a kind of barbadosnut seed dregs of rice and protein concentrate preparation ", remove the toxic component in the little seeds of a tung oil tree cake with ethanol elution.People such as Liu Qiang have applied for that " poison-removing method (201110020815.2) of leprosy seeds benevolence after a kind of de-oiling " also is that method with extraction using alcohol removes the toxic component in the cake.People such as Diao Qiyu have applied for " application (200910250517.5) of jatropha curcas detoxification meal in cattle fattening concentrated feed ", do not relate to concrete poison-removing method.Above-mentioned these patents all are to adopt methyl alcohol or ethanol to make the method for solvent lixiviate, and wash-out removes the toxic substance in the little seeds of a tung oil tree cake.There is the problem that production cost is high, the toxicity of toxalbumin does not have removal in this method.
Mikrobe can produce the abundant enzyme of kind, can degrade to complex compound, successfully has been used to remove the toxicity of multiple grouts, and fermentation method is one of various meal expeller and mealsolvent detoxifications method commonly used, makes feed like rapeseed cake, cotton seed cake detoxification.Owing to contain certain antimicrobial substance in the little seeds of a tung oil tree cake, add that its protein contnt is high, a lot of mikrobes can not grow the toxic component in the little seeds of a tung oil tree cake of can not degrading fast on little seeds of a tung oil tree cake.Wang Xinghong has applied for patent " strain is used to remove the toxic streptomyces fimicarius of little seeds of a tung oil tree grouts " (201110254056.6); Though this strain bacterial strain has detoxification efficiency preferably; But can not in grouts, add other organic matter; Like wheat bran etc., otherwise can increase the toxicity of little seeds of a tung oil tree cake on the contrary, reason it be unclear that.On the other hand, its detoxification efficiency is stable not enough.
About aspergillus versicolor A003 bacterial strain; Wang Xinghong has applied for " strain be used to ferment little seeds of a tung oil tree grouts make the aspergillus versicolor of bio-bacterial manure " (201110254026.5); This bacterial strain little seeds of a tung oil tree grouts that can ferment, the little seeds of a tung oil tree cake after the fermentation has good fertilizer effect.Through experiment discovery repeatedly, use the little seeds of a tung oil tree grouts of this bacterial strain detoxification also can be used as feed, so this patent of application.Do not see the report that aspergillus versicolor is used to produce little seeds of a tung oil tree cake detoxified feed as yet.
