A method for producing bacteria belonging to the genushaving excellent viability even under various conditions with different environmental factors, novel bacteria belonging to the genusobtained by the method, and a method for detecting the bacteria are provided. By subculturing and storing bacteria belonging to the genusalternately in systems under conditions with different environmental factors, the bacteria belonging to the genusexhibiting excellent viability under all the conditions used for the alternate subculturing and storing can be produced.

A bone metabolism improving agent characterized by containing as the active ingredient fermented soybean milk which is obtained by fermenting soybean milk with a lactic acid bacterium or a bifidobacterium. The bone metabolism improving agent is efficacious in treating and preventing diseases in association with lowered bone metabolism such as osteoporosis and, at the same time, satisfies requirements in cost and smooth intake.

Bone metabolism improving agent

Athat is resistant to acid and bile and which retains at least 20% viability after acid and bile treatment. Foods and drinks containing an acid- and bile-resistant. Methods for providing viableto the intestine after ingestion of a food or drink containing an acid- and bile-resistant

Method of evaluating the extent of reaching the intestine of bifidobacterium in fermented milk food or drink

A strain provided is showing a viable count of 1&times;10 cells/ml or more immediately after culturing in a soymilk medium and sustaining a viable count of 1&times;10 cells/ml or more after storage at 10&deg; C. for 14 days. The strain is preferably FERM BP-6223, and is used for producing fermented soymilk.
