In addition, the lactobacillus fermentum also has higher safety and genetic stability, is one of the earliest planted probiotics in human intestinal tracts, can continuously change along with the growth of human ages and the change of human bodies, and can influence the health of human bodies when the number of the probiotics is lower than a normal value.
Lactobacillus fermentum is widely present in the intestinal tract of humans and animals and is excreted with faeces. Lactobacillus mucilaginosus is a part of the normal flora of the human body, which is one of the important components of the normal microbial system of the intestinal tract and accompanies the host for life, and has important significance for maintaining the microecological balance of the intestinal tract. Meanwhile, as probiotics in intestinal flora, the fermented mucus lactobacillus is also edible lactobacillus, has no toxic or side effect, can play a role in helping intestinal peristalsis, and can also enhance the digestion capability of human bodies, improve immunity and the like. At present, fermented lactobacillus mucilaginosus has become a hot spot of research as a probiotic lactobacillus mucilaginosus with great potential and is being continuously used to make probiotic preparations suitable for human and animals.
Currently, different strains of lactobacillus fermentum have been reported to have different probiotic functions: (1) enhancing host immunity. For example, the lactobacillus mucilaginosus CECT5716 can effectively prevent, relieve and treat common uncomfortable symptoms of pregnant women and lactating women, help the fetus to pre-establish an intestinal immune protection system before birth, and remarkably improve the immunity and the resistance of infants. (2) antibacterial: preventing respiratory tract infection, reducing incidence of common cold, cough, etc., and preventing vaginal infection. (3) improving intestinal health: promoting health of gastrointestinal digestive system, reducing harmful substances in intestinal tract, and relieving constipation. (4) Helping the fetus build an autoimmune system, and laying a foundation for the innate immunity of the baby. (5) Effectively preventing and treating mastitis, relieving mammitis, relieving breast soreness, relieving pain, promoting breast health, and relieving tension and anxiety.
It can be seen that the diversity of sources of lactobacillus mucilaginosus results in genetic and functional diversity. However, the current studies on the separation and identification, the probiotics characteristics and the metabolic mechanism of the lactobacillus fermentum are still relatively few, which also affects the further development and utilization of the lactobacillus fermentum to a certain extent. Therefore, it is necessary to make lactobacillus mucilaginosus function better according to different sources of the lactobacillus mucilaginosus, such as determining the efficacy according to the functions of the strain or the probiotics metabolite, and defining the application prospect. In conclusion, the research and application of the probiotic fermented lactobacillus mucilaginosus have wider development space.

Example 1 isolation and characterization of Lactobacillus fermentum JF5
The lactobacillus mucilaginosus Limosilactobacillusfermentum JF strain is separated from pickle samples in Guangdong province of China, and is specifically as follows:
repeatedly cleaning pickled cabbage samples for one month purchased from the new phoenix comprehensive meat and vegetable market in Guangzhou sea pearl area with sterile water for 3 times, placing the pickled cabbage samples in a mortar, adding sterile water (v/m=1:10), thoroughly grinding the pickled cabbage samples into homogenate, sucking a proper amount of grinding fluid by a pipette, coating the grinding fluid on an MRS flat plate, and culturing the pickled cabbage pickle samples at room temperature for 3 days. The colonies to be streaked and purified in the separation experiment plates were numbered with a marker and strain numbers were marked on the plates accordingly. Colonies were picked and inoculated onto MRS plates and the strains were purified by plate streaking. If the strain cannot be separated by the method, colonies need to be picked from the enrichment plate, and the colonies are coated on the MRS plate after being subjected to gradient dilution by the MRS liquid culture medium. Reference is made to the "Berger's Manual of identification of bacteria" (eighth edition) and the "manual of identification of fungi" which identify strains belonging to bacteria first, and then the growth of colonies is observed. The purified strain is obtained through preliminary separation, the strain number is JT1, and after 24 hours of culture, bacterial colonies of the strain are observed to be round, milky white, smooth in surface, raised and neat in edge.
Next, after molecular identification by 16S rDNA universal primer (27F: AGAGTTTGATCCTGGCTCAG,1492R: TACGGCTACCTTGTTACGACTT), the isolated L.fermentum JF5 strain was subjected to whole genome sequencing by Beijing Baimeike biosciences Corp. The resulting 16S rDNA sequence (SEQ ID No: 1) was subjected to BLAST alignment at NCBI' S Genome database. The results show that the JF5 strain has >99% homology with the 16S rDNA sequence of the known lactobacillus fermentum (l.fertum); and performing evolution analysis with homologous strains (FIG. 1), confirming that strain JF5 is a different strain of Lactobacillus mucilaginosus.
Finally, strain JF5 is preserved, and the preservation information is as follows: preservation time: 2022, 10 and 4; preservation unit name: china Center for Type Culture Collection (CCTCC); deposit number: cctccc No. M20221511; deposit unit address: chinese university of Wuhan; classification naming: limosilactobacillus referenced.
Lactobacillus fermentum is a probiotic bacterial strain approved by the country for use in food, has wide probiotic effects such as antibacterial, anti-inflammatory and improving health of mother and infant, but different sources of bacterial strains have different effects, which means that the novel lactobacillus fermentum JF5 isolated from kimchi samples according to the present invention can be used as a probiotic and may have novel effects and functions.

Example 2 function of Lactobacillus mucilaginosus (Lactobacillus fermentum) JF5 and use thereof
(1) Protease capable of producing degradable milk protein by fermenting lactobacillus mucilaginosus JF5 strain
The identification and measurement of the ability of lactobacillus mucilaginosus JF5 to secrete proteolytic proteins was performed according to the agar well diffusion assay using a skim milk plate medium (MP plate). In the test, 3uL of lactobacillus mucilaginosus JF5 bacteria solution with the concentration of 10Abs is dripped into the test group, and 3uL of blank MRS culture medium is dripped into the control group. The cells were cultured in an anaerobic incubator at 37℃for 3 days in an inverted manner. The results showed that JF5 significantly degraded protein and formed a distinct degradation circle (fig. 2) compared to the control with the blank medium, indicating that lactobacillus mucilaginosus JF5 produced protease.
Therefore, the lactobacillus mucilaginosus JF5 can promote the digestion and absorption of protein in food by human body and improve the absorption of small peptide and amino acid when used as a probiotic bacterial strain. And can be used for resisting allergy (improving food allergy caused by protein dyspepsia or non-absorption). In addition, the method can also be used for extracting protease and is applied to the production in the protease fields of food industry, washing industry and the like; can also be used in microbial feed to help animals digest and absorb nutrition, and improve the utilization rate of the feed.
(2) Cellulase produced by fermenting lactobacillus mucilaginosus JF5 strain
The identification and measurement of the cellulose degrading ability of lactobacillus mucilaginosus JF5 were carried out according to the agar well diffusion method, with slight modification, and the cellulose plate medium used was MP medium. In the test, 3uL of lactobacillus mucilaginosus JF5 bacteria solution with the concentration of 10Abs is dripped into the test group, and 3uL of blank MRS culture medium is dripped into the control group. Congo red staining was performed after 3 days of inversion culture in an anaerobic incubator at 37 ℃. The results show that JF5 can significantly degrade cellulose and form a distinct degradation loop compared to the control with the blank medium (fig. 3), indicating that lactobacillus mucilaginosus JF5 can produce cellulase.
It can be seen that probiotic fermented lactobacillus mucilaginosus JF5 strains can serve several purposes by producing the efficacy of cellulases: (1) to facilitate the digestive absorption of dietary components; (2) improving constipation: the cellulose is decomposed in the intestinal canal to generate certain moisture, and the effect of softening the stool is achieved; (3) Cholesterol reduction is the most important effect of cellulose, because the soluble fiber can inhibit the absorption of cholesterol by human body after being absorbed by human body, can be combined with cholesterol in intestinal tract, quickens the metabolism of cholesterol in human body, prevents human body from inducing hyperlipidemia due to hypercholesteremia, and can also reduce the incidence rate of arteriosclerosis and coronary heart disease; (4) The non-sweet 'sugar' of cellulose can slow down the absorption of glucose by blood, balance the concentration of blood sugar and promote the sensitivity of muscle and fat cells to insulin, thereby preventing and assisting in treating diabetes.
In addition, the lactobacillus mucilaginosus JF5 can also be used for fermenting and extracting cellulase, and has wide application in the food industry and the environmental industry; can be applied to degrading cell walls of pathogenic fungi and controlling diseases; can be applied to the decomposition of cellulose in compost; can also be used for preparing livestock and poultry raising feed, such as monogastric animal feed for pigs, chickens and the like, so as to overcome the defect that cellulose cannot be utilized.
(3) Fermentation of Lactobacillus mucilaginosus JF5 strain produces gamma-aminobutyric acid (GABA)
Culturing Lactobacillus fermentum JF5 in MRS liquid culture medium to stationary phase, spreading in new MRS liquid culture medium at dilution ratio of 1:30, collecting bacterial suspension when culturing to stationary phase for 24 hr, centrifuging at 10,000Xg and 4deg.C for 10min, collecting cultured thallus, and collecting thallus with buffer PBS (8 g NaCl, 0.2g KCl, 1.44g Na are weighed 2 HPO 4 、0.24gKH 2 PO 4 Dissolving in 800mL distilled water, regulating the solution to 7.2 with HCl, adding distilled water to a volume of 1L to obtain PBS buffer solution, and determining GABA concentration of cultured thallus by using GABA specific ELISA kit (CEA 900 Ge). The results showed that the concentration of GABA in the cell lysate of JF5 was significantly increased compared to buffer PBS used for lysing cells, and that the cumulative amount was 18.16pg/mL, indicating that Lactobacillus fermentum JF5 can produce gamma-aminobutyric acid in the stationary phase (FIG. 4).
Gamma-aminobutyric acid is an important central nervous system inhibitory neurotransmitter, and is widely present in animals, plants and microorganisms. It has been demonstrated that GABA, a small molecular weight non-protein amino acid, is food safe and can be used as a food additive. Research shows that intake of a certain amount of GABA has the physiological effects of improving sleeping quality of organisms, resisting depression, resisting anxiety, reducing blood pressure, improving lipid metabolism, enhancing memory and brain activity, accelerating brain metabolism, strengthening liver and kidney, promoting ethanol metabolism (dispelling alcohol effect), improving climacteric syndrome and the like.
Thus, the probiotic fermented lactobacillus mucilaginosus JF5 strain can exert the above multiple uses by the effect of producing gamma-aminobutyric acid.
(4) The lactobacillus mucilaginosus JF5 strain can produce and secrete Hyaluronic Acid (HA)
Lactobacillus fermentum JF5 cultured with MRS liquid medium to stationary phase was expanded into new MRS liquid medium at a dilution factor of 1:30, bacterial suspension was collected at 24h of stationary phase, and after centrifugation at 10,000×g at 4 ℃ for 10min, the supernatant of the fermentation broth was collected, and the HA concentration of the supernatant of the fermentation broth was determined by means of hyaluronic acid (also known as hyaluronic acid, HA) specific ELISA kit (CEA 182 Ge). The results showed that the concentration of HA in the fermentation supernatant of JF5 was significantly increased compared to the low concentration of HA in the blank medium MRS, with an accumulated amount of 9.96ng/mL, indicating that lactobacillus mucilaginosus JF5 can produce and secrete hyaluronic acid in the stationary phase (fig. 5).
Hyaluronic acid, also known as hyaluronic acid, is a biodegradable, biocompatible, non-toxic, non-allergenic polymer with a variety of biological functions. Has anti-inflammatory and anti-angiogenesis effects, and has strong anti-aging, moisturizing and wrinkle smoothing abilities. The anti-wrinkle agent is beneficial to skin anti-wrinkle, promotes wound anti-inflammation and healing, can be used as an anti-wrinkle agent, and has the potential of developing skin cosmetics. In addition, HA HAs high lubricating, water absorbing and retaining ability, and can affect various cell functions such as migration, adhesion and proliferation, so that HA is also widely used in biomedical fields such as ophthalmic surgery, arthritis treatment, wound healing scaffolds, tissue engineering, implant materials, and the like.
Thus, the probiotic fermented lactobacillus mucilaginosus JF5 strain can exert the above multiple uses by the efficacy of hyaluronic acid production.
(5) The fermentation liquor of the lactobacillus mucilaginosus JF5 strain can effectively inhibit the activity of alpha-glucosidase
Lactobacillus fermentum JF5 cultured with MRS liquid medium to stationary phase was expanded into new MRS liquid medium at a dilution ratio of 1:30, bacterial suspension was collected at 24h of stationary phase, and after centrifugation at 10,000×g at 4 ℃ for 10min, the supernatant of the fermentation broth was collected, and the effect of the supernatant of the fermentation broth on the enzyme activity ability of α -glucosidase to hydrolyze glucose was measured by an α -glucosidase inhibitor screening kit (ab 284520). The results showed that the fermentation supernatant of JF5 significantly inhibited the ability of α -glucosidase to hydrolyze glucose compared to the non-inhibitory effect of the blank medium MRS, with an inhibition rate of about 58.82%, indicating that the fermentation broth of lactobacillus mucilaginosus JF5 can effectively inhibit the activity of α -glucosidase (fig. 6).
Alpha-glucosidase, an enzyme that plays a role in carbohydrate breakdown, is associated with type 2 diabetes, and inhibition of alpha-glucosidase is one of the methods of controlling postprandial hyperglycemia, thereby contributing to the treatment of diabetes. Thus, α -glucosidase inhibitors help to maintain blood glucose levels and can improve diabetic complications. Furthermore, inhibition of α -glucosidase activity may control obesity.
Thus, the probiotic fermented lactobacillus mucilaginosus JF5 strain has an alpha-glucosidase inhibitory activity, which makes it a potential hypoglycemic and obesity inhibiting probiotic.
(6) Fermented lactobacillus mucilaginosus JF5 strain fermentation liquor can effectively inhibit acetylcholinesterase activity
Lactobacillus fermentum JF5 cultured with MRS liquid medium to stationary phase was expanded into new MRS liquid medium at a dilution ratio of 1:30, bacterial suspension was collected at 24h of stationary phase, and after centrifugation at 10,000×g at 4 ℃ for 10min, the supernatant of the fermentation broth was collected, and the inhibitory ability of the supernatant of the fermentation broth against acetylcholinesterase (AchE) activity was measured by means of acetylcholinesterase inhibitor screening kit (KA 6219). The results showed that the fermentation supernatant of JF5 significantly inhibited the activity of acetylcholinesterase compared to the non-inhibitory effect of the blank medium MRS, with an inhibition rate of about 3.47%, indicating that the fermentation broth of lactobacillus mucilaginosus JF5 can effectively inhibit the activity of acetylcholinesterase (fig. 7).
The acetylcholinesterase inhibitor can continuously accumulate at synapses under the action of acetylcholine released by nerve fiber tips through reversible inhibition of acetylcholinesterase, excite cholinergic receptors, and prolong and increase the action of acetylcholine. Acetylcholinesterase inhibitors can enhance cognitive ability and memory (improve Alzheimer's disease, improve cognitive dysfunction), dilate blood vessels (improve heart rate overspeed), excite skeletal and smooth muscles (improve constipation, postoperative abdominal distension, postoperative urinary retention).
Thus, the probiotic fermented lactobacillus mucilaginosus JF5 strain can inhibit acetylcholinesterase activity, and excite skeletal muscle and smooth muscle of intestinal tract, which makes it a potential probiotic for promoting gastrointestinal absorption and peristalsis.
Taken together, the novel isolated lactobacillus mucilaginosus strain JF5 of the present invention has a variety of probiotic effects: (1) has excellent protease activity; (2) has excellent cellulase activity; (3) gamma-aminobutyric acid can be produced and secreted; (4) can produce and secrete hyaluronic acid; (5) can inhibit alpha-glucosidase activity; (6) can inhibit acetylcholinesterase activity. Therefore, the lactobacillus mucilaginosus strain JF5 has important application value and economic value.
