Description
Technical field
What the present invention relates to is a kind of method of producing polypeptide enramycin with zymotechnics, belongs to Agricultural biotechnologies, industrial biotechnology, field of fermentation engineering.
Background technology
Microbiotic makes an addition in the feed in order to promote animal growth and development and to improve the existing nearly 60 years history of feed report that many countries are the prolonged application Antibiotic Additive all.Yet, being accompanied by being extensive use of of antibiotics growth promoter, a series of problems also appear gradually, mainly are drug residue and resistance problem.For a long time, extensive, indiscriminately use antibiotic feed to have brought great trouble and difficulty for the control of bacteriosis and treatment, also bring potential to threaten simultaneously to human beings'health.Though, facts have proved at present about whether should in feed, using microbiotic to have numerous disputes, reasonably use Antibiotic Additive can promote growth of animals or poultry, improve food conversion ratio.Also there is simultaneously report to show, forbids that the country that adds microbiotic or other antibiotic growth promoters in feed can cause the increase of livestock industry production cost, profit to reduce, and also might cause such as the problems such as trade war between ecotope and the country simultaneously.In fact, Antibiotic Additive has only they comprehensively is familiar with and reasonably application still in a large amount of uses, just can give full play to its advantageous effect, and avoid human health is worked the mischief.The task of top priority is the resistance at microorganism, research and development wide spectrum, efficient, safe novel fodder additive, and this can not only bring remarkable economic efficiency, also has extremely important social effect.
Enramycin (Enramycin) is a kind of wide spectrum, efficient, safe novel fodder additive.It has another name called grace bleomycin, grace mycin, enramycin, is a kind of polypeptide antibiotics that is produced by streptomycete fermentation.As a kind of brand-new feed specialist additive, have following characteristics: the enramycin that 1. adds trace in the feed just can promote the weightening finish to livestock and poultry.2. have intensive antimicrobial acivity, can suppress the harmful bacterium (clostridium) in the intestines especially energetically gram-positive microorganism.3. because absorptivity not, only its effect of performance in alimentary canal can not residue in the livestock and poultry body.4. and between existing clinically microbiotic or the antimicrobial drug there is not cross resistance.Sensitive organism produces resistance to enramycin hardly, and under experiment condition, chemical sproof generation is also very slow, even occur, resistance is also unstable, and very easily loses.Therefore the long-term continuous time spent, its effect can not be affected yet.5. satisfactory stability is arranged in feed.In addition, enramycin also has hepatitis B virus (HBV) antigen and hepatitis B virus e antigen (HBeAg) and suppresses effect preferably.Just because of so many advantage is arranged, enramycin has become a line products of antibiotic feed additive for promoting growth.
Scholarly forecast, as a kind of animal specific microbiotic, enramycin also can serve as the leading role of growth promoter in considerable time, because it both can satisfy the requirement of people to security, can significantly reduce the animal product cost again.But present enramycin complex technical process, fermentation time is long, the production cost height, unit tires low.
Summary of the invention
The objective of the invention is at above-mentioned weak point, screen a strain enramycin and produced bacterium, and provide a kind of method of producing polypeptide enramycin with zymotechnics, according in the strain growth metabolic process to the difference of oxygen demand, control dissolved oxygen stage by stage, this is integrated fermentations of multistage such as an aerobic, little oxygen, and adopts stream to add the method for carbon source, has realized the high-density culture of enramycin production bacterium streptomycete.The method technological process of producing polypeptide enramycin with zymotechnics of the present invention is simple, and production cost is low, the enramycin height of tiring in the unit volume fermented liquid.
Adopt streptomycete Streptomyces sp.NJWGY3665 in the method for producing polypeptide enramycin with zymotechnics of the present invention, this bacterium adds nutritive substances such as glucose by stream in initial low glucose concentrations (1%) fermentation, production process, and according to having realized high efficient fermentation under the situation of fermentation different steps to the demand difference of dissolved oxygen, enramycin is tired and is reached 6100 μ g/mL in the unit volume fermented liquid.
Streptomycete Streptomyces sp.NJWGY3665 bacterial strain is to separate to obtain from the soil of school district, Nanjing University of Technology Jiangpu.This streptomyces species is deposited in China Committee for Culture Collection of Microorganisms common micro-organisms center at present, registering on the books and number in this preservation center is CGMCCNO.2410, classification name: streptomycete, the Latin formal name used at school of bacterial classification is Streptomyces sp., the microorganism (strain) of ginseng certificate: NJWGY3665, preservation date are on March 21st, 2008.
The method of producing polypeptide enramycin with zymotechnics is to take following mode to realize:
The method of producing polypeptide enramycin with zymotechnics is:
1, slant culture: streptomycete Streptomyces sp.NJWGY3665 bacterial classification is received in the glucose nutritional medium, carry out slant culture, the weight percent proportioning of glucose nutritional medium is glucose 0.5~1%, extractum carnis 0.5~1%, peptone 0.5~1%, NaCl 0.3~0.5% or K
2HPO
