1. Parameters of vitamin B12 requirement ofSkeletonema costatum were measured in continuous culture and compared with those ofMonochrysis lutheri.

2. The specific growth rate depended on the cell quota according to the relation
$$\mu = \mu _m \left( {1 - \frac{{k_Q }}{Q}} \right)$$
rather than directly on the medium concentration.
