Lactobacillus LGG has been replicated from a human intestinal microbiota. It was discovered by Professors Gorbach and Goldin, giving name to the strain.
BB-12 is a lactic-acid producing bacteria that comes from a proprietary dairy culture collection. When it was first classified, it was thought to belong to the species Bifidobacterium bifidum, which is where the “BB” came from. Though the classification has now changed to Bifidobacterium animalis subsp. lactis, the name has not.
