Description
Technical Field
The invention relates to the technical field of biological fermentation engineering, in particular to a method for improving the accumulation of polyphenol in Phellinus linteus cells by using unsaturated fatty acid.
Background
The medicinal fungi of Phellinus basidiomycota are valuable medicinal materials in China. Phellinus linteus is recorded in Ben Cao gang mu and has the functions of benefiting five viscera, xuan Chang stomach qi and expelling toxin. Researches show that the Phellinus linteus contains a plurality of active ingredients such as polysaccharide, triterpene, polyphenol, organic acid and the like, and the ingredients have remarkable activities in the aspects of resisting tumor, protecting liver, resisting oxidation, resisting bacteria, diminishing inflammation, enhancing organism immunity and the like [1-4]. The polyphenol compounds are composed of one or more hydroxyl groups, and are mainly classified into flavonoid compounds, pyrone compounds, furanone compounds and the like, and have higher antioxidant activity [5]. The flavonoid has antioxidant, antitumor, vasodilating and antibacterial effects; the pyrone compound has stronger capability of scavenging free radicals and biological activity of inhibiting NF- κB pathway; furanone compounds have antibacterial, antiviral and anticomplement activity [6-7].
Although wild-type Phellinus linteus can produce various active substances, in nature, the growth of Phellinus linteus is strict to the environment and fruiting bodies grow slowly. Along with the increasing market demand, wild resources are less and less, and artificial cultivation of Phellinus linteus becomes a focus of attention. However, under the condition of artificial fermentation culture, the accumulation amount of the secondary metabolite of Phellinus linteus is very low, and the production requirement cannot be met. This is because the genes involved in the synthesis of secondary metabolites from Phellinus linteus are all in a low-expression or silent state under artificial culture conditions. The research shows that after the fungi are stimulated by the external environment, the fungi can generate a series of response reactions, so that the biological expression level of genes is influenced, the enzyme activity is changed, and finally, the accumulation of secondary metabolites is improved.
The liquid fermentation culture has the characteristics of controllable conditions, short growth period and the like, however, the problem of low yield of active ingredients exists in the fermentation process of the phellinus linteus, so that how to increase the content of the active ingredients of the phellinus linteus by the exciton becomes an important research content under the condition of liquid fermentation.

The shake flask was removed and broken up thoroughly with a hand-held homogenizer under sterile conditions. Placing in a constant temperature shaking table, culturing at 26 deg.C for 5 days at 150 rpm. Namely mother liquor. Can be used for subsequent liquid fermentation. Liquid fermented Phellinus linteus (S.vaninii) is divided into three groups, namely a control group containing no unsaturated fatty acid in the medium, and an experimental group containing 0.5g/L and 1g/L unsaturated fatty acid. Samples were taken at 5d, 7d, 9d, 11d and 13d of culture.
3. Determination of the amount of biomass

TABLE 1 gradient elution procedure
Example 2: effect of linoleic acid on Phellinus Linteus biomass accumulation and polyphenol Synthesis
1. Variation of mycelium biomass
Adding different amounts of linoleic acid into Phellinus linteus liquid culture medium to make the concentration of linoleic acid in the culture medium respectively be: 0. 0.5g/L, and medium without linoleic acid is used as control. Both 0.5g/L and 1g/L linoleic acid can promote the increase of the biomass of the Phellinus linteus mycelium, and the mycelium growth speed at the concentration of 0.5g/L linoleic acid is the fastest in the fifth day of growth. With the increase of the culture time, the promoting effect of the concentration of 1g/L linoleic acid is more obvious after the seventh day, and the biomass is higher than that of the control group and 0.5g/L concentration. Until day 13, the concentration of linoleic acid was 1g/L, and the biomass of Phellinus linteus reached 6.9g/L, which was 53.33% higher than that of the control group (FIG. 1).
2. Variation of mycelium polyphenol accumulation
In the early stages of the growth of Phellinus linteus, linoleic acid showed no promoting effect on the accumulation of intracellular polyphenols. However, the intracellular polyphenol content of the experimental group to which linoleic acid was added was gradually higher than that of the control group (no linoleic acid was added) and the linoleic acid promoting effect was more remarkable at the concentration of 0.5g/L, and at the time of 11 days, the intracellular polyphenol content of the linoleic acid group at the concentration of 0.5g/L reached 5.37mg/g, which was 48.75% higher than that of the control group at the time of 3.61mg/g (FIG. 2).
3. Accumulation of the Compound Hispin
The difference of polyphenol composition under different culture conditions is detected by using an HPLC method by taking Hispin as a standard substance. As can be seen from FIG. 3, on days 5-7, the increase in Hispin content after treatment with 1g/L linoleic acid was relatively pronounced, with 0.5g/L and 1g/L concentrations reaching maximum values on days 9 and 13, 43.08. Mu.g/mg and 39.45. Mu.g/mg, respectively.
Example 2 Effect of linolenic acid on Phellinus Linteus biomass accumulation and polyphenol Synthesis
1. Effects on biomass accumulation
Different amounts of linolenic acid are added into the Phellinus linteus liquid culture medium, so that the concentration of the linolenic acid in the culture medium is respectively as follows: 0. 0.5g/L, and 1g/L of culture medium without linolenic acid is used as a control. Sampling according to growth time of mycelium, namely 5d, 7d, 11d and 13d, taking out 3 groups of samples, separating fermentation liquor and mycelium by filtration, fully drying, weighing dry weight of mycelium, recording, and finishing to obtain the chart 4. As can be seen from FIG. 4, the mycelium biomass increased at a smooth increase, with 0.5g/L and 1g/L linolenic acid added, compared to the control group without linolenic acid added. And on day 13, the dry weight of mycelium reaches the highest at each concentration, the control group is 3.99g/L, the 0.5g/L linolenic acid experimental group is 4.76g/L, and the 1g/L linolenic acid experimental group is 5.16g/L, wherein the growth promotion effect of the experimental group added with 1g/L linolenic acid is the best, and the dry weight of the experimental group is increased by 1.17g/L compared with that of the control group.
2. Changes in accumulation of polyphenols
On day 5, the total polyphenol content of the 0.5g/L experimental group was highest in the three groups of samples. The data from days 7 to 14 show that the experimental group with 1g/L linolenic acid added had the most pronounced promoting effect with increasing growth time, whereas the experimental group with 0.5g/L linolenic acid stimulated, although the content increased less than 1g/L, still increased compared to the control group. Eventually each group reached a maximum at day 13 and the total polyphenol content of both groups at this time with linolenic acid addition of 0.5g/L and 1g/L was approximately the same, increasing by 0.46mg/g compared to the content of the control group at this time (FIG. 5).
3. Accumulation of the Compound Hispin
FIG. 6 shows that starting on day 9, the Hispin content of the linolenic acid-added experimental group was higher than that of the control group, and that the linolenic acid-added experimental group with 0.5g/L was highest on day 13, reaching 8.17. Mu.g/mg.
