Chlorella 培養過程中 N＾15標識에 關한 硏究 = A Study on N＾15 uptake of chlorella in the Course of Culture

다국어 초록 (Multilingual Abstract)

Since chlorella was found to be a source of protein 1947, wide ranges of investigations on culture methods, its constituents and nutritional factors have been carried out, i. e. most of them are reports on nutritional theses. However, kinetics such as absorption, distribution, metabolism and elimination of chlorella protein are not fully elucidated. So, on the assumption that using N^15 labelled chlorella protein could accomplish good results for kinetics of chlorella in invivo experiments, N^15 was added into the culture fluid. As the results, parallel increases of N and N^15 in chlorella algae were observed as shown in Fig. 1. From the above results, it is suggested that chlorella utilizes N as well as N^15 in protein synthesis, and this N^15 labelled chlorella protein can be useful tool for study of kinetics of chlorella in invivo experiments.
