Succeeding to the previous experiments1), vitamin B group contents of the extracts and the fresh matter of squid and oyster were estimated by bioassay. The results obtained were as follows:
1) In squid and oyster, no considerable seasonal variations were found in the B group content (Tables 2, 3).
2) Vitamin B group contents both in the extracts and the fresh matter of squid and oyster increased progressively during storage, and the increase was conceived to be caused by a bacterial action.
