The present invention provides a bacterium belonging to the genus, which can exhibit a high viability in the storage under agitation and can produce a fermented food containing a large number of viable bacterial count. The present invention further provides a fermented food, which contains the bacterium belonging to the genusand exhibits various physiological effects such as inhibitory action against harmful intestinal bacteria and intestinal function controlling effects. The present invention further provides a bacterium belonging to the genushaving a rate of viability of 30% or more, when the bacterium is stored in the aerobic condition under agitation at 10&#xb0; C. for 14 days after culturing in a medium containing milk as a main ingredient until obtaining a viable count of 1&#xd7;10cfu/ml or more, and fermented food using the same.
