✦ Synopsis

The Metabolism o/ Bacterium bifidum ( Lactobacillus bifidus) XI. Communication: Vitamin8 Requirement in Tomarelli' s Solution Summary. Strains No. 8 and TIs sI~ of Bacterium bifidum (]3. b.) were incubated in ToM~m~I'S solution. From this medium, thiamine, riboflavin, pyridoxine, calcium pantothenate and nicotinic aeid amide were withheld respectively or altogether in the performance of different experiments. Growth of the cells was estimated after each passage by evulation of the packed volume. In general, the propagation of cells is impaired by the withdrawal of the vitamines from the TO~AR~LLI solution. In the absence of all five vitamines, the rate of multiplication was the smMlest one. Pantothenic acid seems to be of outstanding importance for the increase of a B.b. culture. The role of B.b. as a supplier of riP,mines is not sufficienly defined as yet and needs further investigation.
