Physiological Characteristics and Anti-obesity Effect of Lactobacillus plantarum K10
Seulki Kim,Eunchong Huang,Soyoung Park,Wilhelm Holzapfel,Sang-Dong Lim 한국축산식품학회 2018 한국축산식품학회지 Vol.38 No.3
This study aimed to investigate the physiological characteristics and anti-obesity effects of Lactobacillus plantarum K10. The α-amylase inhibitory activity, α-glucosidase inhibitory activity, and lipase inhibitory activity of L. plantarum K10 was 94.66±4.34%, 99.78±0.12%, and 87.40±1.41%, respectively. Moreover, the strain inhibited the adipocyte differentiation of 3T3-L1 cells (32.61±8.32%) at a concentration of 100 μg/mL. In order to determine its potential for use as a probiotic, we investigated the physiological characteristics of L. plantarum K10. L. plantarum K10 was resistant to gentamycin, kanamycin, streptomycin, ampicillin, ciprofloxacin, tetracycline, vancomycin, and chloramphenicol. It also showed higher Leucine arylamidase, Valine arylamidase, and β-galactosidase activities. Moreover, it was comparatively tolerant to bile juice and acid, exhibiting resistance to Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes, and Staphylococcus aureus with rates of 90.71%, 11.86%, 14.19%, and 23.08%, respectively. The strain did not produce biogenic amines and showed higher adhesion to HT-29 cells compared to L. rhamnosus GG. As a result of the animal study, L. plantarum K10 showed significantly lower body weight compared to the high-fat diet group. The administration of L. plantarum K10 resulted in a reduction of subcutaneous fat mass and mesenteric fat mass compared to the high-fat diet (HFD) group. L. plantarum K10 also showed improvement in gut permeability compared to the HFD positive control group. These results demonstrate that L. plantarum K10 has potential as a probiotic with antiobesity effects.

Probiotic Property and Anti-Obesity Effect of Lactiplantibacillus plantarum KC3
Kim, Seulki,Huang, Eunchong,Ji, Yosep,Holzapfel, Wilhelm Helnrich,Lim, Sang-Dong Korean Society for Food Science of Animal Resource 2022 한국축산식품학회지 Vol.42 No.6
Lactic acid bacteria are representative probiotics that have beneficial effects on humans. Nineteen strains among the 167 single strains from kimchi was selected and their physiological features were investigated. The selection of a strain was based on strong enzyme (lipase, α-amylase, and α-glucosidase) inhibitory activities and anti-obesity effects in the adipocytes. For the final selection, the strain Lactiplantibacillus plantarum KC3 was tested for its potential as a starter. To assess its functionality, a freeze-dried culture of L. plantarum KC3 was administered to a diet-induced obese mouse model receiving a high-fat diet. The animal group administered with L. plantarum KC3 showed significant body weight loss during the 12-week feeding period compared to the high-fat control group. This study investigated the physiological characteristics of selected strain and evaluated its potential as an anti-obesity probiotic in mice.
