title: Ribosomal ribonucleic acids from Streptomyces griseus.
abstract: Nucleic acids from Streptomyces griseus 178 were isolated during cultivation. After their fractionation on a column of methylated serum albumin adsorbed on Kieselguhr, the 16 S and 23 S RNA were isolated. To characterize RNAs their sedimentation coefficients, Tm and nucleotide composition were determined. During cultivation of S. griseus 178 rRNA level reaches two maximum peaks and the production of streptomycin influences nucleic aicds of the producer organism.
