The synthesis of vitamin B is of general occurrence among microorganisms. Negative results of some investigators may be accounted for by inadequate amounts fed or too limited feeding periods. Our experiments showed the following organisms to elaborate vitamin B when tested by the rat weight test: Saccharomyces cerevisiae, Torula rosea, Oospora lactis, Bacillus adhaerens, Bacterium coli (three strains), Bacillus subtilis and Bacillus mycoides.
