Description of Lacticaseibacillus rhamnosus H15

Cells are Gram-stain-positive, non-flagellated, and rod shaped. Colonies are yellowish or white colored, circular, convex, and glistening when incubated for 3 days on MRS agar plates at 30°C. In the API 20NE system, positive results for esculin hydrolysis and β -galactosidase; but negative for nitrate reaction, indole production, D-glucose fermentation, arginine dihydrolase, urease, and gelatin hydrolysis. D-Glucose, L-arabinose, D-mannose, D-mannitol, N -acetyl- β -glucosamine, D-maltose, potassium glutamate, capric acid, adipic acid, malic acid, trisodium citrate, and phenylacetic acid are not utilized as sole carbon sources. Strain H15 (= NIBRBAC000509646) was isolated from a breast milk sample at Ansan, Gyeonggi-do, Republic of Korea.
