Description

A kind of trichoderma aureoviride bacterial strain and the method for preparing acid Chinese quince tobacco aromaticss with it
Technical field
The invention belongs to microbial fermentation and its application fields, and in particular to one plant of trichoderma aureoviride new strains HLMM-04, together When, the invention further relates to the methods for preparing acid Chinese quince tobacco aromaticss using the bacterial strain.
Background technique
Flavoring and casing is the key link in cigarette process, is effective promotion cigarette smoking quality, forms the peculiar wind of cigarette One of effective means of lattice.The tobacco aromaticss added in China tobacco at present are deployed again using conventional method extraction mostly Gained there is also fragrance dullness, improves the disadvantages of cigarette smoking effect is unobvious although production operation is simple.Utilize micro- life Object, which ferments to perfume material, can increase the content that tradition extracts a variety of aroma substances in fragrance, and promotion fragrance is rich, into And produce that fragrance is abundant, cigarette of high-quality, meet requirement of the consumer to cigarette quality.
Trichoderma (Trichoderma spp.) is distributed widely in nature, rotten wood, seed, plant residue, organic fertilizer, It is outstanding more in soil and air.Trichoderma growing nutrient requires simply, and the speed of growth is fast, highly beneficial for industrialized production.It is yellow Green trichoderma (Trichoderma aureoviride) is one kind of trichoderma, as a kind of important bio-control factors, to phytopathy Former antagonism has broad spectrum activity, property mostly processed, moreover it is possible to generate the plant and animal residues in a variety of enzymes decomposition soil, increase soil Fertility.Have to the report of trichoderma aureoviride focus mostly on soil improvement, biological control and in terms of.In the prior art There is not yet trichoderma aureoviride is used for the report that acid Chinese quince fermentation prepares tobacco aromaticss.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide one plant of trichoderma aureoviride new strains, which has Cellulase-producing, and then promote cellulose decomposition at the ability of oligosaccharides or monosaccharide.
The object of the invention is also to provide a kind of methods for preparing tobacco aromaticss using the strain fermentation acid Chinese quince.
The purpose of the present invention is achieved by the following technical programs.
Unless otherwise indicated, percentage of the present invention is mass percent.
A kind of trichoderma aureoviride (Trichoderma aureoviride) HLMM-04 bacterial strain, CGMCC No.10839, tool There is cellulase-producing, and then promotes cellulose decomposition at the ability of oligosaccharides or monosaccharide.
The method for preparing tobacco aromaticss using the bacterial strain, comprising the following steps:
(1) it by after the activation twice of trichoderma aureoviride HLMM-04 CGMCC No.10839 bacterial strain, is inoculated in equipped with 200mL PDA In the triangular flask of fluid nutrient medium, at 20~35 DEG C, 1~7d of fermented and cultured under 180rpm;The PDA liquid medium: horse Bell potato 200g, glucose 20g mend distilled water to 1L, pH5.5~8.5,115 DEG C of high pressure sterilization 15min;
(2) filtering fermentation liquor removes thallus, takes supernatant to be slowly added to sulfate of ammoniac to 80% saturation degree, stood at 4 DEG C Night is collected by centrifugation sediment and is dissolved in 2mL buffer, then dialysed with buffer, obtains crude enzyme liquid;The buffer Are as follows: 0.02mol/L Na2HPO4-NaH2PO4, pH 7.3;
(3) acid Chinese quince decontamination is cleaned, the water of double weight is added after being crushed, is uniformly mixed, adjusts pH to 6.0;It is added yellow Green trichoderma HLMM-04 crude enzyme liquid, fermentation, crude enzyme liquid additive amount are the 5%~20% of acid Chinese quince quality, and fermentation temperature is 30 DEG C, Fermentation time 5h;Supernatant is concentrated under reduced pressure to get required tobacco aromaticss for refluxing extraction 3h, filtering and removing slag.
Further, to prevent fragrance rotten, propylene glycol is added by the 5% of tobacco aromaticss weight.
In step (1) optimum condition of enzyme production be initial pH 6.5,28 DEG C of cultivation temperature, incubation time 5d.
Compared with the existing technology, the invention has the following advantages that
(1) trichoderma aureoviride is applied to tobacco aromaticss preparation field for the first time by the present invention.Using trichoderma aureoviride HLMM-04 bacterial strain Fermentation liquor treatment acid Chinese quince, compared with untreated control, while original acid Chinese quince characteristic perfume is kept, promoting the production of body fluid, it is prominent to act on Out, throat's irritation reduces, and pleasant impression improves.
(2) present invention is low in cost, easy to operate, is easy to implement large-scale industrial production, application prospect is good.
The explanation of preservation biomaterial
It is common to be deposited in China Committee for Culture Collection of Microorganisms to bacterial strain of the invention on May 22nd, 2015 Microorganism center (CGMCG);The centre address: city, BeiJing, China, North Star West Road 1, Chaoyang District institute 3, the micro- life of the Chinese Academy of Sciences Object research institute.The strain classification is named as trichoderma aureoviride (Trichoderma aureoviride) HLMM-04, and deposit number is CGMCC No.10839。
