摘要：When asakusanori was incubated in artificial seawater, it released a significant amount of vitamin B₁₂. The rate of release was very high at the beginning of incubation and steeply decreased. Four-fifths of the released B₁₂ was a macromolecule-bound form and the rest was free form, of which some were taken up by the asakusanori tissue. Asakusanori took up the free form B₁₂ from the incubation medium by concentration and temperature-dependent processes. The amount of uptake increased with the time of incubation and did not attain a plateau after 4h. The capacity was retained even after storage in frozen state for 11 months.
