Enhanced Activity of Pyruvic Kinase in the Potassium-Deficient Wheat Leaves

Isolation and screening tests were carried out to obtain microorganisms capable of producing amino acids from pentoses and hexoses directly in the presence of nitrogen sources and inorganic sails.

Three strains having exceedingly high amino acids producing ability were obtained. One of them produces remarkably l-glutamic acid and alanine and the other two have high productivity of alanine.

As a result of the taxonomical studies, all of these strains were found to belong to the Genus Brevibacterium. Moreover, there are no species which conform to these strains described in Bergey’s Manual of Determinative Bacteriology 7th Ed., so the authors decided them to be new species.
