Description

Soil-repairing agent and its production method and application of the height containing polyphenol oxidase
Technical field
The invention belongs to agriculture microbe technologies, and in particular to a kind of high soil-repairing agent containing polyphenol oxidase and Its production method and application.
Background technology
Polyphenol oxidase (polyphenol oxidase, EC 1.10.3.1) is the oxidoreducing enzyme of a kind of cupric, is had Extensive substrate, can not only a variety of aromatic compounds of catalysis oxidation, moreover it is possible to lignin degrading, many toxic aldehydes matters of removal Toxicity, a variety of dyestuffs and its waste water decoloring can also be made, therefore in papermaking, environmental protection, food, medical and health, biological detection etc. Field polyphenol oxidase has larger research and application value.Since polyphenol oxidase can also aoxidize many organic contaminations Object, and particularly important effect is played in soil aromatic series organic matter humification process, therefore it is in terms of soil remediation Application potential also gradually it is in widespread attention.
China's agricultural straw resource enriches, and annual output is occupied about at 700,000,000 tons or so first of the world according to statistics, and average Every year still with 1251.2 ten thousand tons of speed steady-state growth, wherein corn, rice and wheat stalk yield is maximum, but straw utilization is imitated Rate is relatively low.In recent years, when every summer and autumn crops are rush-harvested and rush-plant, often figure facilitates saving of labor to save trouble to peasant, usually pays stalk One of torch.Open Burning Crop Residue is the rich and influential family of agricultural pollution, since stalk is mostly imperfect combustion under open-air atmosphere, is generated big Measure the pollutant of harmful to human respiratory tract.The dense smog triggered is burned, makes a very bad impression to air environment, also be easy to cause The communal facilitys such as electric wire, cable, communication line are damaged, and are triggered fire, are caused people and animals' injures and deaths and property loss, even resulting in can see Degree declines, and Flights Delayed normally takes off, interferes highway normal operation repeatedly.Therefore, recycling China stalk resource It develops eco-agriculture significant with sustainable agriculture.
China is time-honored food and drink big country, and the special eating habit of our people causes the big volume production of kitchen garbage It is raw.It is counted according to urban construction department of the Ministry of Construction, China generated 3.9 ten thousand tons of kitchen garbages 3.9 hundred million urban population day.The rubbish of such enormous amount It can not quickly be dissolved in city, all flow to the rural area of surrounding city, this brings white elephant to the environment in rural area, also gives Illegal retailer feeds swill pig, it is hidden that this feeding manner also brings serious food security with opportunity with kitchen garbage Suffer from.
The grease weight of kitchen garbage, fat content are high, putrefactive phenomenon, micro- life can occur mostly in storage, transportational process Object, bacterium amount reproduction.Wherein contain the pathogenic microorganism of a large amount of infectious diseases common to human beings and animals, not only easily cause zoogenetic infection husky Door bacterium disease, colibacillosis etc. more than 10 plants infectious disease, and pathogenic microorganism colonizes in the internal procreation of pig, into food chain Afterwards, human infection disease (such as hepatitis) can be caused, " the recessive bomb " for being known as communicable disease is caused to be broken out by sanitationist. Meanwhile the leftovers of starch etc are also easily generated under the action of bacterium and gone mouldy.Contained by putrid and deteriorated swill Various toxin can cause endotoxin contamination to domesticated animal, and such as the Aflatoxin that aspergillus flavus generates, the kojic acid that aspergillus oryzae generates is all With very strong carcinogenicity, the diseases such as intestinal cancer, stomach cancer, liver cancer, kidney, breast cancer can be caused.
The harmless treatment of kitchen garbage is imperative, this problem has also caused the great attention of government.By In kitchen garbage water content is high, fat content is high, salinity weight, calorific value is low the features such as, with landfill, burn, compost the methods of handle Effect is undesirable.Expensive processing cost simultaneously also virtually adds the difficulty of kitchen garbage improvement.Therefore, in kitchen On the governing problem of rubbish, preferable method be not only solve rubbish it is innoxious, reduce environmental pollution, ensure that food security is defended It is raw, while more resource reutilization, maximum limit are carried out with the means of science using kitchen garbage as a kind of available resource The waste of the reduction resource of degree could also solve food-safety problem and environmental problem from source.
