Description

Burkholderia vietnamiensis strain and its use for improving hair or scalp condition {Burkholderia vietnamiensis strain and its use for improving hair or scalp condition}

It relates to novel microorganisms, their lysate, culture solution, extract, fermented solution, and their use for improving hair or scalp condition.

In the human body, hair grows from hair follicles on the scalp, and cycles such as anagen, catagen, and telogen are continuously repeated throughout life, and they go through generation, growth, and loss (Paus et al. , J Invest Dermatol. 113, pp. 523-532, 1999). In the degenerative phase of the hair follicle, the growth of the hair follicle is stopped, apoptosis and the reorganization of the extracellular matrix occur. As the number of hair follicle cells in the degenerative and resting state of the hair follicle increases, the hair falls out and does not grow back. .

Hair is divided into visible and invisible hair roots, and the root from which hair grows is called the hair bulb, and the recessed part at the bottom is called the dermal papilla (Fig. One). The dermal papilla is the most important part in the development of hair and has blood vessels and nerves to deliver nutrients and growth factors to promote hair growth. Since the number of hairs decreases due to apoptosis and reduction in growth of dermal papilla cells, proliferation of dermal papilla cells is required for maintenance and increase of hair.

In addition, in the case of seborrheic scalpitis in which scalp lipids are excessively secreted, sebum secreted from the hair follicles sebaceous glands is increased by the action of androgen hormones, and as the sebum increases, the amount of microorganisms present in the scalp increases. These scalp microorganisms can generate waste products on the scalp and cause hair loss accompanied by itching and pain (Journal of the Korean Society of Aesthetics, Vol. 18 No. 2 (2012), pp. 279-289).

Recently, as environmental pollution and urban stress become serious, the number of modern people with alopecia increases, and interest in materials that can improve it is increasing. Therefore, it was attempted to invent a material that can help to strengthen the hair root and prevent hair loss by inducing hair growth by increasing the expression of the growth factor of the dermal papilla cells responsible for the initiation of hair generation among the hair roots. In addition, it was attempted to invent a material that solves inflammation and itchiness caused by sebum by using microbial cells and strain cultures that inhibit scalp lipids, and further prevents hair loss symptoms.

In this regard, Korean Patent No. 10-2102578 discloses a cosmetic composition for promoting hair growth or hair growth containing a plurality of compounds. However, there are not many studies on microorganisms that can improve the condition of hair or scalp.

Probiotics are microorganisms that have beneficial effects on the human body. Most probiotics known to date are known as lactic acid bacteria. Although probiotics have been reported to produce effective efficacy through various beneficial effects on the human body, studies on the interaction between the scalp flora and the scalp are scarce.

Accordingly, there is a need for the development of flora on the scalp that can be usefully used for scalp-related conditions.

Hereinafter, the present invention will be described in more detail through examples. However, these examples are for illustrative purposes only, and the scope of the present invention is not limited to these examples.

Example 1. Isolation and identification of strains

A sample was obtained by washing the scalp of a male in his 20s with a healthy scalp with sterile distilled water. The sample was inoculated into R2A (Reasoner's 2A) liquid medium or solid medium (manufacturer: Difco). After culturing in a 28 ℃ incubator for 48 hours after inoculation, 100 formed colonies were separated and cultured in pure water, and cultured in a 28 ℃ incubator for 48 hours. The cultured colonies were subjected to 16S rRNA sequence identification. The primers used at this time were designed to amplify in response only to bacteria. PCR amplification was carried out in 30 cycles of 95°C for 1 minute, 55°C for 1 minute, 75°C for 1 minute and 30 seconds each, and finally maintained at 72°C for 8 minutes and then stored at 4°C. After the PCR reaction was completed, the DNA sequences of the isolated and cultured species were determined using ABI-3730XL (ABI, USA).

When the nucleotide sequence of the 16S rRNA region determined from the isolated and cultured microbial colonies was compared with other strains registered through the BLAST program provided on the website of the National Center for Biotechnology Information (NCBI), homology 97 % or less of novel species were selected, and among them, a novel microorganism Burkholderia vietnamiensis ( Burkholderia vietnamiensis ) with less than 98% homology (hereinafter referred to as "SP-7") was selected. The selected SP-7 strain was deposited with the Korea Microbial Conservation Center on October 28, 2020 and was given an accession number KCCM12821P. SP-7 strain has a 16S rRNA sequence of SEQ ID NO: 1 (complementary DNA).

Experimental Example 1. Evaluation of the efficacy of increasing human hair papilla cell (HFDPC) proliferative capacity

In order to evaluate whether the culture medium of the SP-7 strain isolated in Example 1 significantly induces the proliferation of dermal papilla cells, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyl-2H-tetrazolium bromide) analysis was performed.

First, human hair papilla cells (HFDPC) were aliquoted in a 96-well plate at a rate of 2x10 ⁴ cells/well, and then cultured for 24 hours in an incubator at 37° C. and 5% CO ₂ conditions. Then, after changing to a medium containing nothing, 1% (w/w) of the culture solution of the SP-7 strain was added and further cultured for 24 hours. A group in which 10 ppm of minoxidil (Minoxidil, MXD, 6-piperidin-1-ylpyrimidine-2,4-diamine 3-oxide), known as a hair growth promoter, was added instead of the strain culture medium was set as a positive control group, and the medium not containing the strain culture medium The addition group (medium con) was set as a negative control, and the non-addition group (None) was also set as a control to confirm the efficacy of the strain culture. After 24 hours, the medium from each well was removed and washed once with DPBS (Dulbecco's phosphate buffered saline), and then 500 μl of 0.5 mg/mL MTT (Sigma-aldrich, St. Louis, USA) was included in each well. medium and reacted at 37°C for 4 hours. Then, the absorbance was measured at 570 nm using Victor 3 (Perkin-Elmer). The cell viability was expressed as a percentage of the measured average absorbance value, and through this, the proliferative capacity of human hair papilla cells (HFDPC) can be confirmed.

Figure 2 is the result of confirming the effect of increasing the proliferative capacity of dermal papilla cells.

As shown in Figure 2, it was confirmed that the strain of Example 1 exhibits an excellent dermal papilla cell proliferation effect.

Therefore, it was confirmed that the SP-7 strain can be used for strengthening hair roots, preventing hair loss, and promoting hair growth.

Experimental Example 2. Scalp Lipid Inhibition Efficacy Evaluation

In order to evaluate whether the culture solution of the SP-7 strain isolated in Example 1 inhibits scalp lipids, lipid inhibition evaluation was performed after inducing lipid peroxide to keratinocytes.

Specifically, human keratinocytes (HaCaT) were seeded in a 6-well plate at a rate of 3x10 ⁵ cells/well, and then cultured in cell culture conditions for 24 hours. After 24 hours, the medium was discarded, washed with PBS, and diluted with 1% (w/w) peroxidated squalene in a medium not containing FBS, and lipid peroxide was induced by adding it to the cells. Then, 1% (w/w) of the culture solution of the SP-7 strain was added and further cultured for 72 hours. A 1% (w/w) addition group (medium con, RCM control) containing no strain culture medium was set as a negative control. The medium was discarded and washed three times with PBS, and then Nile red O staining was performed to stain the lipids of the cells. Nile red solution (1 mg/ml in acetone) was diluted 1/1000 in FBS-free medium and added to the cells, and 10 minutes later, it was placed in an IncucyteZoom (Essen BioScience) instrument and photographed with a fluorescence microscope and fluorescence intensity was quantified. did

As shown in Figure 3, it was confirmed that the strain of Example 1 exhibits an excellent lipid inhibitory effect.

Therefore, it was confirmed that the SP-7 strain can be used for suppressing scalp lipids, preventing dandruff, improving or suppressing scalp inflammation and itching due to sebum, preventing hair loss due to lipid peroxide, and scalp health.
