Attenuation of Cell Stimulating Bacteria by Specific Amino Acids

Abstract

Attenuation of Phytomonas tumefaciens was accomplished by 20-30 transfers in a mannitol nitrate-mineral salts medium containing 0.1-0.3% glycine adjusted to pH 6.8. Other attenuating compounds were alanine, serine, [alpha] amino n-butyric acid, threonine, valine, norvaline, methionine, leucine, nor-leucine, isoleucine and lycine.
