Secretion of DNases and RNases, respectively, was found in saprophyte bacteria isolated from nature and growing on media containing DNA and RNA. Serratia marcescens and Bacillus subtilis with a high nuclease activity can assimilate RNA and DNA as the main source of nutrition. Ser. marcescens with a nuclease which attacks both DNA and RNA can grow equally(More)
The catabolism of uracil and the total balance of excreted radioactivity were studied in golden hamsters after a peroral application of 14C-uracil. Twenty-four hours after administration most of the radioactivity taken up appeared in expired carbon dioxide. The percent proportion of radioactivity in carbon dioxide was independent of the amount of uracil(More)
