Influence of aminoacid requirement on the growth of Bifidobacterium globosum strains.
A general procedure has been devised for the determination of amino acid requirements in Bifidobacterium globosum strains, based upon identification of individual amino acids singularly deprived of the defined synthetic medium. In the plasmid-positive and plasmid-negative clones of RU 809 and T 19 strains, we found a correlation between the presence of plasmid and L-leucine auxotrophy. This characteristic is not shared by the other 145 strains, 26 of which are plasmid-positive, of the B. globosum species.
