PETERSON Departments of Biochemistry and Plant Pathology, University of Wisconsin Received for publication July 12, 1940 Downloaded from http://jb.asm.org/ on December 9, 2011 by deepdyve The growth factors and minor metallic elements required for the best development of the crown-gall organism, Phytomona8 tumefaciens (Smith and Town.) Bergey et al., have been examined in contimuing studies on its nutrition. The importance of sources of nitrogen and carbon and certain physical chemical factors has been shown by several investigators (e.g., Sagen et al., 1934, Pinckard, 1935). They worked mostly with media containing animal or plant extracts which doubtless supplied the materials that were necessary only in minute quantities. With a suitable synthetic medium (Van Lanen, Baldwin and Riker, unpublished) and an adequate means of growing the cultures so as to secure reproducible results (McIntire, Peterson and Riker, 1940) the way was opened to study various growth-stimulating
