The previous reports described the nucleic acid related substances and their degrading enzymes in the process of the sake brewing. The present report deals with the nucleic acid related substances and their degrading enzymes, and behaviors of these enzymes in the culture filtrate of sake yeast and washed cells suspended in a buffers solution. The results obtained were as follows : 1) The 260mμ absorbing materials and RNase activity in the culture broth were increased gradually in the logarithmic phase of the growth of yeast.2) The RNase produced for mononucleotides during the degradation of yeast RNA.3) Ethyl alcohol and calcium chloride promoted the excretion of the 260 mμ absorbing materials from the washed cells in the buffer solution.4) Glucose promoted the leakage of RNase and PMase from the washed cells in the buffer solution.
