Abstract
A method of separating nonpaline derivatives from their diastereoisomers is disclosed along with a method of selectively growing strains of the bacterium A. tumefaciens. Also disclosed are novel general methods of synthesizing the nopaline and isonopaline of this invention. These novel compounds are useful for the selective growth of the agriculturally useful A. tumefaciens bacterium.
