STUDIES ON THE BIOASSAY OF PYRIMIDINES AND NUTRITIONAL REQUIREMENT OF LACTOBACILLUS BREVIS : (II) GROWTH POTENCY OF POLYNUCLEOTIDES AND THEIR HYDROLYZED PRODUCTS

Abstract

In previous paper, it was confirmed that Lactobacillus brevis required for its growth, uracil, cytosine or their nucleoside and nucleotide and orotic acid. Further examination was made with the growth effect of RNA, DNA, apuric acid and deamino-DNA. It was confirmed that these polymers were not effective while chemical or enzymatical hydrolysates of these compounds were effective.
