Embodiment 1

[0060] Adipocyte differentiation inhibition and fat accumulation inhibition in 3T3-L1 preadipocytes

[0061] In order to confirm the adipocyte differentiation inhibitory effect and the intracellular fat accumulation inhibitory effect in preadipocytes of the Lactobacillus rhamnosus LM1019 strain deposited with the Korean Collection of Microorganisms under the accession number KCCM12308P, the following experiments were performed.

[0062] First, differentiated adipocyte staining was accomplished using Oil Red O on 3T3-L1 preadipocytes treated with 1% LM1019 culture extract, 10% LM1019 culture extract, and phosphate buffered saline as a control, 1 The stained cells were observed by microscopy after 1 hour.

[0063] like figure 1 As shown, as a result of comparison with the control group to which phosphate buffered saline was added instead of the LM1019 culture extract, it was confirmed that the number of fat globules (arrows) in the adipocytes of the treated group treated with t...

[0067] Neutral lipolysis promotion and accumulation inhibition in 3T3-L1 adipocytes

[0068] In order to confirm the amount of intracellular neutral fat (TG, triglyceride) accumulated in the process of differentiation into adipocytes, 1% and 10% of the extract of the LM1019 strain were added and cultured, respectively. As a control group, phosphoric acid was used. Buffered saline solution was used instead of strain extract for cultivation. Adipocytes from day 9 of differentiation were obtained and used.

[0069] The obtained cells were washed three times with a phosphate buffered saline solution and the cells were disrupted, and then centrifuged at 15,000 rpm under a temperature condition of 4°C, and the supernatant was used as a sample. 10 μL of the sample and 150 μL of an enzyme reagent were added, and the reaction was carried out under normal temperature conditions for 15 minutes to measure the absorbance at 530 nm.

[0070] The results of the measurement of neutral fat i...

[0076] Determination of lipolytic enzyme (lipase) activity

[0077] In order to confirm the lipolytic enzyme (lipase) activity of the LM1019 strain, the following experiments were performed.

[0078] By preparing a lipase production medium, LM1019 was streaking in a loop, and incubated at a temperature of 37°C overnight. When lipase is produced, olive oil (olive oil) in the medium is decomposed to produce monoglyceride (monoglyceride).

[0079] Monoglyceride emits light in ultraviolet (UV) at 350 nm by binding to Rhodamine B (Rhodamin B) in the medium, and a comparison experiment was performed with a control group using Escherichia coli (E.coli), the control group and the LM1019 strain group Neither glowed.

[0080] The concentration of monoglyceride in the control group was 0.75 nmol / well, and the concentration in the LM1019 strain group was 0.70 nmol / well. Compared with the control group, there was no difference in the concentration of monoglyceride in the strain group.

Abstract

The present invention relates to a Lactobacillus rhamnosus LM1019 strain (accession number: KCCM12308P), and a composition for preventing and treating obesity or diabetes including same. Specifically,the Lactobacillus rhamnosus LM1019 strain according to the present invention reduces fat cells, neutral lipids, subcutaneous fat, and cholesterol, thus having an obesity prevention and treatment effect, and also reduces the blood concentrations of glucose and insulin, thereby suppressing insulin resistance and thus having a diabetes prevention and treatment effect.

Description

technical field [0001] The present invention relates to a novel Lactobacillus rhamnosus LM1019 strain and a composition comprising the same for preventing and treating obesity or diabetes. Specifically, the Lactobacillus rhamnosus LM1019 strain of the present invention has the effect of preventing and treating obesity by reducing adipocytes, neutral fat, subcutaneous fat and cholesterol, and at the same time suppressing blood sugar concentration and insulin concentration by reducing Insulin resistance to prevent and treat diabetes. In addition, Lactobacillus rhamnosus LM1019 is also involved in the expression of lipase as a lipolytic enzyme, leptin as an appetite regulating hormone, and the obesity-related gene carnitine palmitoyltransferase (CPT). Background technique [0002] Recently, due to the improvement of income level and the development of industries, the diet and eating habits have been rapidly westernized, and the number of patients with chronic diseases and adul...
