The word probiotic is coined by Kollath (1953) and is
derived from the Greek language, which means "for life" .
According to Lilly and Stillwell (1965), probiotics are
substances produced by microorganisms that promote the
growth of other microorganisms. However, the widely
adopted definition states probiotics as Blive microorganisms
which when administered in adequate amounts confer
a health benefit on the host^ (FAO/WHO 2001).
