The first to isolate a pure lactic acid bacterium for the above purpose was, as has been …

Micro-organsims were first discovered about 250 years ago. Antonie van Leeuwenhoek (1632-1723), a Dutch civil servant, learned how to make excellent lenses from which he also built some of the earliest microscopes.
