抄録

The balance of vitamin B₁₂ in massculture of the rotifer Brachionus plicatilis was calculated for both batch and semicontinuous cultures after the evaluation of B₁₂ concentrations in Nan-nochloropsis, yeast, rotifer and culture water. The B₁₂ output, which is taken as the total of B₁₂ harvested and left remaining in a tank, was 1.6-2.2 times larger than the B₁₂ introduced with food, water and inoculum. On the other hand, among 100 bacterial strains isolated from rotifer tanks, 35 had B₁₂ productivity and 19 of them promoted the growth of the rotifer effectively when supplied with yeast. Calculated from the feeding rate, the B₁₂ content of bacteria and the B₁₂ demand of the rotifer, it is proved that the greater part of B₁₂, the essential vitamin to the rotifer is produced by bacteria existing in water, and excess amount was transferred to the rotifer automatically by grazing.
