Description
Technical Field
The invention belongs to the technical field of microbial genetic engineering, and particularly relates to bacillus licheniformis for efficiently synthesizing hydroxytyrosol, a construction method and application thereof.
Background
Hydroxytyrosol (HT), also known as 3, 4-dihydroxyphenylethanol, is a bioactive polyphenol and one of the strongest natural antioxidants known today. Hydroxytyrosol can scavenge free radicals, reduce oxidation of low density lipoprotein, and stimulate calcium deposition. It also has anticancer, anti-inflammatory and antimicrobial activity. Therefore, hydroxytyrosol can be used in cosmetics, food, health products and medical industry.
At present, HT is industrially produced by plant extraction or chemical synthesis. In nature, HT is present in olive plants in the form of oleuropein, and hydroxytyrosol can be extracted from fresh olive leaves and olive processing wastewater. Although these materials are abundant and inexpensive, they suffer from drawbacks such as low yields, strong acid water vapor and long duration of the process. Chemical synthesis utilizes some analogues of HT, such as 3, 4-dihydroxyphenylacetic acid, 3, 4-dihydroxybenzaldehyde, tyrosol, etc. as substrates to synthesize hydroxytyrosol, and these methods are not suitable for large-scale industrial production due to expensive substrates, poor conditions, complicated steps or low yield.
With the progress of metabolic engineering and synthetic biology, the de novo production of HT from simple carbon sources has been achieved by either rebuilding the natural pathway or introducing artificial biosynthetic pathways in microorganisms. At present, most reports utilize escherichia coli to synthesize hydroxytyrosol through microbial modification, which lays an important foundation for producing hydroxytyrosol by a microbial fermentation method. However, the method for synthesizing HT from the head by using a simple carbon source has the problems of long synthetic route, heavy metabolic burden, low efficiency and low substrate conversion rate, and further improvement of the de novo efficiency is needed to realize economic production of HT.

Example 4:
construction of recombinant strains expressing mutant kivD (V461A and V461I) and hpaBC in combination of different promoters
Step 1: the plasmid pHY-Pbaca-kivD used in example 3 was used V461A -P43-hpaBC and pHY-Pbaca-kivD V461I -P43-hpaBC as a template, and Pbaca (shown in SEQ ID NO. 93) and P43 and Pbay (shown in SEQ ID NO. 94) as promoters, respectively, to construct expression vectors of 18 different combinations. To construct pHY-P43-kivD V461I P43-hpaBC as an example, the P43 promoter was amplified with the P43-kivD-F/R primer and pHY-Pbaca-kivD with the P43 fragment as a template V461I pHY-P43-kivD was amplified using-P43-hpaBC as a template and kivD-T5-F/R primer V461I -P43-hpaBC vector backbone; using a one-step cloning kit, the P43 promoter fragment and pHY-P43-kivD were cloned V461I -P43-hpaBC Linear backbone, ligation by chloroTransferring the ligation product into Escherichia coli DH5 alpha by calcium transformation method, screening by culture medium containing tetracyclic resistance at 37 deg.C, screening to obtain transformant, and naming as co-expression vector pHY-P43-kivD V461I -P43-hpaBC. The construction method of the other 15 different combination expression vectors is similar to pHY-P43-kivD V461I -P43-hpaBC。
The remaining 15 combination expression vectors are shown in the following table:

Step 2: the constructed 18 recombinant plasmids expressed in different combinations and the control vector pHY300 are electrically transformed into a recombinant strain DH7, and 18 recombinant bacillus licheniformis HT 2-HT 19 and HT0 control strains are obtained.
Example 5:
recombinant Bacillus licheniformis hydroxytyrosol fermentation
1) Seed fermentation: activated Bacillus licheniformis DW2/pHY-300, HT0 and different recombinant Bacillus licheniformis HT 1-HT 19 on the plate, inoculating the bacteria to 250mL triangular flasks containing 50mL liquid LB, and culturing at 37 deg.C and 230rp m for 13 h. Then inoculating the fermentation medium with an inoculation amount of 2% (volume ratio); the culture condition of the hydroxytyrosol fermentation medium is 37 ℃, the culture is carried out for 48h at 230rpm, and the yield of the hydroxytyrosol is measured after the fermentation is finished.
The formula of the hydroxytyrosol fermentation medium is 10g/L peptone, 5g/L yeast powder, 10g/L NaCl and 18.6g/LK 2 HPO 4 ，5.2g/LKH 2 PO 4 70g/L glucose, pH 7.0, the remainder being water.
2) Pretreatment of fermentation liquor: diluting the fermentation liquor with deionized water, centrifuging to remove thallus, and filtering with 0.22 μm water phase filter membrane.
3) Hydroxytyrosol was detected by High Performance Liquid Chromatography (HPLC). The measurement conditions are specifically as follows: using Agilent 1260 hplc, column C18 (4.6mm ID × 250mm,5 μm), mobile phase methanol: 0.1% formic acid 2: 8, the flow rate is 0.6mL/min, the column temperature is 30 ℃, the sample injection amount is 10.0 mu L, the detection wavelength is 224nm, and the elution time is 25 min. And calculating the content of the hydroxytyrosol in the fermentation liquor according to a standard curve made of a hydroxytyrosol standard product. As a result, hydroxytyrosol was not detected in the control strains DW2/pHY-300 and DH0, but in both recombinant strains, H T7 (pHY-P43-kivD) was detected V461A Pbay-hpaBC) and HT16 (pHY-P43-kivD) V461I -Pbay-hpaBC) strain yields up to 5.55 + -0.37 and 5.49 + -0.33 g/L.
