Description

Vibrio H11 and application thereof
Technical Field
The invention belongs to the field of microbial biotechnology and resource biotechnology, and particularly relates to vibrio H11 and application thereof.
Background
Enteromorpha (Enteromorpha) is a large green alga, and belongs to the plant of the Chlorophyta (Chlorophyta) order Ulvales (Ulvalles) family Ulvaceae (Ulvaceae). In recent years, due to global warming and seawater eutrophication, enteromorpha can grow rapidly, and great influence is brought to the marine ecological environment. In the early stage, the enteromorpha is buried and burned, so that the surrounding water and soil are seriously polluted, and the waste of biomass resources is caused. How to effectively utilize the explosive resource of enteromorpha has become a research hotspot for improving the marine ecological environment and comprehensively utilizing the seaweed.
Enteromorpha as a large green alga is a potential renewable biofuel source and can be used for preparing bio-oil, methane or ethanol and the like. However, due to the complex and unclear components of the enteromorpha polysaccharide, researchers have less research on high-value utilization of enteromorpha and have little application of the enteromorpha and the enteromorpha polysaccharide in the aspects of active oligosaccharide or biological energy. At present, the enteromorpha is mainly treated by a hydrothermal method, a rapid pyrolysis method and a fermentation method. But the fuel oil obtained by a hydrothermal method and a fast pyrolysis method is difficult to be directly utilized; therefore, the microbial enzyme method is favored by a large number of researchers. At present, the main carbon sources for producing alcohols and acids by microorganisms are monosaccharides such as glucose, xylose and fructose, and the cost is too high. However, the enteromorpha prolifera which is an explosive resource can be hydrolyzed into fermentable reducing sugar which is used as a novel biological energy source in raw materials.
Disclosure of Invention
The invention aims to provide vibrio H11 and application thereof, and aims to solve the problems that researches on high-value utilization of enteromorpha by researchers are few due to complex and unclear enteromorpha polysaccharide components at present, so that the scheme for researching the enteromorpha utilization is single, the method is mainly a physical and chemical method at present, and the method has great limitation and the like.
In order to solve the problems, the invention provides Vibrio H11(Vibrio sp.h11) which is preserved in the China center for type culture Collection in 31/3/2018, wherein the preservation numbers are as follows: CCTCC NO: m2018172, depository address: wuhan university collection, eight-way 299 in Wuchang area, Wuhan city, Hubei province. The strain can grow in a culture medium with enteromorpha polysaccharide as a unique carbon source, and is a gram-negative bacterium; the physiological and biochemical characteristics are positive VP, positive MR and negative gelatin liquefaction. Can grow and hydrolyze enteromorpha green tide biomass serving as a unique carbon source and energy into clostridium fermentable reducing sugar for anaerobic fermentation to generate biological hydrogen, biological organic solvent and the like.
The culture method of the vibrio H11 comprises the following steps: inoculating the Vibrio H11 strainThe enteromorpha polysaccharide is used as the only carbon source for growth, and the composition of the culture medium is (1L) (NH)4)2SO4,1.0g;Na2HPO4,0.8g;KH2PO4, 0.2g;MgSO4·7H2O,0.2g;CaCl2·2H2O,0.1g;FeCl3·6H2O,5mg; (NH4)6Mo7O24·4H2O,1mg;ddH2O1L; 20g of enteromorpha polysaccharide; tryptone, 5g/L, was cultured at 30 ℃ and pH 8.71 for 12 h. The medium was first sterilized at 121 ℃ for 20 min.
The application of vibrio H11 can be used for hydrolyzing green tide biomass. The method is mainly used for hydrolyzing the enteromorpha into the reducing sugar which can be fermented by the clostridium. The vibrio H11 is used for hydrolyzing enteromorpha polysaccharide in enteromorpha into reducing sugar and then converting the reducing sugar into a biological energy substance through anaerobic fermentation of clostridium. The application method mainly comprises the following steps: adding concentrated crude enzyme solution containing Vibrio H11 into anaerobic fermentation culture medium containing Enteromorpha powder or Enteromorpha polysaccharide, and hydrolyzing in a shaker at 40 deg.C and 200rpm for 48H. Then inoculating clostridium for anaerobic fermentation. The Clostridium may be Clostridium acetobutylicum WA strain.
Enteromorpha polysaccharide is heteropolysaccharide with a complex structure, only the main components of the enteromorpha polysaccharide are known, and the structure of the enteromorpha polysaccharide is not clearly reported at present. For the hydrolysis of the enteromorpha polysaccharide, the mixed flora has better hydrolysis capacity, but the flora composition is easy to change and is difficult to store. The Vibrio sp.H11 strain is used as a single strain, and the enteromorpha polysaccharide hydrolyzing capability of the strain is strongest. For comprehensive treatment and high-value utilization of green tide enteromorpha biomass, the current physical and chemical method has high cost requirement, and the generated waste liquid is easy to pollute the environment. According to the invention, the enteromorpha is finally converted into the biological energy substance by a microbial method, so that the cost is low and the environment is not polluted. At present, the enteromorpha is converted into a biological energy substance by utilizing a microbial fermentation method for the first time.
Compared with the prior art, the bacterial strain capable of efficiently hydrolyzing the enteromorpha polysaccharide is screened, the reducing sugar obtained by hydrolysis of the bacterial strain can be utilized by the energy bacterial strain to generate a biological energy substance, and compared with the existing single bacterial strain for hydrolyzing the enteromorpha polysaccharide, the vibrio H11 in the invention has the strongest hydrolysis capability. The invention realizes high-value utilization of enteromorpha through the combination of the hydrolysis of vibrio and the anaerobic fermentation of clostridium.

(2) Identification of Vibrio sp.H11
Vibrio sp.h11 is a gram-negative strain; the physiological and biochemical characteristics are positive VP, positive MR and negative gelatin liquefaction; the following substances can be used as carbon sources: d-fructose, D-glucose, D-xylose, D-galactose, sucrose, mannitol, citric acid and starch; the results are shown in Table 1.
TABLE 1 physio-biochemical characteristics of Vibrio sp.H11
Figure RE-GDA0001719187750000041
A colony PCR method is adopted, and a single colony is directly taken as a template for PCR. The primers for amplifying the 16S rDNA by using PCR are a pair of universal primers, 27F: 5'-AGAGTTTGATCCTGGCTCAG-3', 1492R: 5'-GGTTACCTTGTTACGACT-3' are provided. The PCR reaction conditions are as follows: 3min at 94 ℃; 30 cycles of 95 ℃ for 30s, 55 ℃ for 30s, and 72 ℃ for 90 s; 10min at 72 ℃. After purifying the PCR amplification product, sending a sequencing result to perform Blast analysis on the sequencing result and a sequence on Genbank, wherein the sequence length is 1385bp, and the invention has great homology with Vibrio coralliilyticus (Vibrio coralliilyticus); the 16S rDNA sequence is shown in SEQ ID NO. 1. The sequence is compared with the sequence in Genbank, similar strains are selected, a phylogenetic tree is constructed by MEGA7 software, and the constructed dendrogram is shown in figure 1. Meanwhile, it was found by electron microscopy of Vibrio H11 that it was rod-shaped and had flagella as shown in FIG. 2.
Vibrio H11 was cultured on an inorganic salt medium plate containing 2% Enteromorpha polysaccharide for 12 hours, and then stained with Lugol's iodine solution to have a clear transparent circle, as shown in FIG. 3.
The vibrio H11 grows by taking enteromorpha polysaccharide as a unique carbon source, generates related glycoside hydrolase, and breaks different types of glycosidic bonds in the enteromorpha polysaccharide, so that oligosaccharides with low molecular weight are generated to provide a carbon source for self growth. The reduced end resulting from the cleavage of the glycosidic bond can be detected by the DNS method. The growth curve of the strain in a culture medium with enteromorpha polysaccharide as a unique carbon source and the reducing sugar content curve chart in fermentation supernatant are shown in figure 4. The concentration of the growth bacteria of vibrio H11 is found to be highest at 14H, which is consistent with the content change of reducing sugar in the culture medium. But the residual reducing sugar content in the fermentation liquor can not directly reflect the enzyme activity of the crude enzyme liquid. Therefore, the fermentation supernatant of the strain is used as a crude enzyme solution to react with a 1% enteromorpha polysaccharide solution, and the enzyme activity (U/mL) of the crude enzyme solution at different fermentation times is measured, and the result is shown in FIG. 5. Before 12h, the enzyme activity of the crude enzyme liquid in the fermentation liquid is gradually increased along with the gradual increase of the fermentation time, the enzyme activity is highest at 12h, and the enzyme activity is slightly reduced after the 12 h.
(3) Optimized culture of Vibrio sp.H11
In order to improve the enzyme activity of the crude enzyme liquid in the fermentation liquid, the culture medium formula and the culture conditions of the vibrio H11 are optimized. The enteromorpha polysaccharide is grown by taking the enteromorpha polysaccharide as a unique carbon source, and the optimized culture medium comprises (1L): (NH)4)2SO4,1.0g;Na2HPO4,0.8g;KH2PO4,0.2g;MgSO4·7H2O,0.2g; CaCl2·2H2O,0.1g;FeCl3·6H2O,5mg;(NH4)6Mo7O24·4H2O,1mg;ddH2O1L, pH 8.71; the culture temperature was 30 ℃.
After the conditions are optimized, the strain is cultured under the optimized conditions, the enzyme activity is measured, and the enzyme activity can reach 8.43U/mL and is obviously higher than the enzyme activity before optimization. Table 2 shows the comparison of the hydrolysis capacities of the strains related to hydrolysis of Enteromorpha prolifera polysaccharide and the vibrio H11 of the invention on the Enteromorpha prolifera polysaccharide. Wherein the crude enzyme solution of Vibrio sp.H11 has higher enzyme activity than the corresponding enzymes of single strain Alteromonas sp.A321 and Alteromonas macleodii B7; meanwhile, the activity of the enzyme is higher than that of Micro-community D2-1 of the mixed bacterial population. Although the enzyme activity is lower than that of Micro-immunity H1, Vibrio sp.H11 is a single strain, and is more stable and easier to store than the strain; micro-community H1 is prone to change the flora structure during the culture process.

(4) Application of Vibrio sp.H11
The crude enzyme solution is obtained after the formula and the culture conditions of the culture medium are optimized, and acts on the anaerobic fermentation culture medium (containing no reducing agent) of enteromorpha powder and enteromorpha polysaccharide with the concentration of 20g/L (2 percent) and 50 g/L (5 percent). The strain H11 of the invention was cultured under optimized culture conditions and samples were taken at 26H of fermentation. In order to obtain more enzyme amount of the crude enzyme solution, enteromorpha polysaccharide or enteromorpha powder is fully hydrolyzed, the crude enzyme solution is ultrafiltered and concentrated at 4 ℃ to collect the crude enzyme solution, and the enzyme activity of the crude enzyme solution is measured. Adding concentrated crude enzyme solution (50ml of Enteromorpha powder or Enteromorpha polysaccharide anaerobic fermentation culture medium (without reducing agent) solution into the anaerobic fermentation culture medium), and hydrolyzing in a shaker at 40 deg.C and 200rpm for 48 h. Then inoculating Clostridium acetobutylicum WA strain for anaerobic fermentation.
When the content of the enteromorpha powder is 2%, the generated biological hydrogen amount is 1553.4mL/L, and the concentration of the biological solvent is 3.46 g/L. When the content of the enteromorpha powder is 5%, the generated biogas amount is 1682mL/L, and the bio-solvent amount is 4.53 g/L. The higher the concentration of the enteromorpha powder is, the higher the yield of hydrogen and the biological solvent is. When the content of the enteromorpha polysaccharide is 2%, the generated biological hydrogen amount is 1473.4mL/L, and the biological solvent amount is 4.77 g/L; when the content of the enteromorpha polysaccharide is 5%, the generated biological hydrogen amount is 3217 mL/L, and the biological solvent amount is 6.74 g/L. The higher the concentration of the enteromorpha polysaccharide is, the higher the yield of hydrogen and a biological solvent is. Meanwhile, comparing the enteromorpha powder and the enteromorpha polysaccharide, the enteromorpha polysaccharide generates more hydrogen and biological solvent under the same concentration. The results are shown in FIG. 6, FIG. 7 and FIG. 8. Through comprehensive comparative analysis, the enteromorpha polysaccharide has the value of producing biofuel.
For the hydrolysis of the enteromorpha polysaccharide, the mixed flora has better hydrolysis capacity, but the flora composition is easy to change and is difficult to store. The strain of Vibrio sp.H11 in the invention is used as a single strain, and the enteromorpha polysaccharide hydrolysis capability of the strain is strongest.
