Some Microbiological Properties of Synthetic Nucleosides.

Abstract
A number of synthetic nucleosides, and chloro- and bromo- derivatives of these nucleosides, were tested for growth-promoting and growth-inhibiting properties on Escherichia coli, strain 9723, and its uracil-re-quiring mutant, E. coli, strain 550-460; Neuro-spora crassa, wild strain Abbott 4A, and a uracil-less strain of Neurospora crassa, No. 1298; and on the growth of Lactobacillus casei and Streptococcus faecalis R.
