Description

A kind of extracting method of grub antibacterial peptide and its application
Technical field
The present invention relates to a kind of extracting methods of antibacterial peptide, and in particular to a method of extracting antibacterial peptide from grub.
Background technology:
Grub also known as hen worm, grub, one's old mother worm, worm etc. when white, build is loose, common name scarab beetle or cockchafer after adult Son, composition are mainly made of fat, protein.
For insect as the more huge species of population quantity type on the earth, insect possesses unique and larger animal not The same immunologic mechanism carries out immune defense by secreting the various immune substances including antibacterial peptide, therefore passes through induction Form promote Insect transformation secret out of all kinds of antibacterial peptides, by its extraction and application, curative effect more preferable than conventional medicament can be obtained Product.
Antibacterial peptide is small molecule peptides active material, is the small peptide with antibacterial activity, is present in different kind organism body It is interior.Antibacterial peptide has certain resistance to microorganism and parasite, but is influenced on organism itself smaller or without influence, and arrives mesh Before until not yet find that antibacterial peptide can make microorganism and parasite generate resistance, be that one kind can be used for substituting resistance getting worse Antibiotic product.
About the extraction application of grub antibacterial peptide, report is less, and traditional extraction process is that directly mashing is obtained by filtration, pure Degree and content are insufficient.
Invention content:
The method that the object of the present invention is to provide a kind of to extract antibacterial peptide from grub, to solve the above technical problems. The present invention can keep it is active under the premise of high efficiency extraction grub antibacterial peptide.
To achieve the above object, the present invention provides following scheme:
The present invention provides a kind of method for extracting antibacterial peptide from grub, includes the following steps:
(1) fresh grub is captured, is cleaned spare;
(2) by Escherichia coli and bacillus subtilis overnight incubation in the medium, according to 1:The bacterium solution of 3~5 volume ratios Mixing, thalline were collected by centrifugation, is resuspended and is precipitated with sterile saline, and as induction source, mixed bacteria liquid is dipped with transfer needle, light to pierce The grub abdomen for entering step (1), continues 1~3d of raising;
(3) grub after inducing step (2) is placed in 75~80% alcohol after immersion 10s, is remained with aseptic water washing Alcohol, be fully ground into homogenate;
(4) homogenate of step (3) is taken, the extracting solution of 10~20 times of volumes is added, then 40~60min of ultrasonic extraction, mistake Filtrate is collected in filter;
(5) filtrate of step (4) is removed into big molecular impurity with ultrafiltration membrane, collects ultrafiltration permeate;
(6) the ultrafiltration permeate of step (5) NF membrane is removed into small molecular weight impurity, collects nanofiltration retentate fluid;
(7) nanofiltration retentate fluid of step (6) is dried in vacuo at 40~50 DEG C, obtains grub antibacterial peptide.
Further, extracting solution is 0.05mol/L ammonium acetate buffers, 35 μ g/ml benzyl sulfonyls in the step (4) Fluorine, 1mg/ml phenylthioureas in proportion 3~5:1:The mixed liquor of 1 composition.
Further, ultrasound condition in the step (4):Power is 150~250W, and frequency is 40~50kHz.
Further, ultrafiltration retaining molecular weight is 10000~12000Da in the step (5).
Further, nanofiltration retaining molecular weight is 200~250Da in the step (6).
Further, the grub antibacterial peptide that said extracted obtains can apply in feed.
Further, the feed is fish meal.
Further, the present invention also provides a kind of fish meals, include the ingredient of following parts by weight:Grub antibacterial peptide 5~10 Part, 10~20 parts of dregs of beans, 10~20 parts of rapeseed meal, 1.2~2.5 parts of multi-vitamins, 1~3 part of cellulase, pectase 1~3 Part.
Compared with prior art, the present invention has following advantageous effect:
(1) it is added to phenylmethylsulfonyl fluoride in extraction process in the present invention, can be prevented by the decomposition of inhibition antibacterial peptide Therefore the antibacterial peptide yield rate generated reduces and quality decline;It is also added to phenylthiourea simultaneously, it can be by increasing protein Solubility property, to increase the recovery rate of antibacterial peptide;
(2) extracting method of the invention uses membrane separation technique, is extracted, is avoided damage to using physical separating process The activity of antibacterial peptide keeps the antibacterial peptide purity higher of acquisition, quality more preferable;
(3) grub antibacterial peptide can be applied in fish meal, improve the immune of fish by antibacterial peptide, reduce morbidity, reach Indirect growth promotion and the effect for improving finished product fish products matter.
