GROWTH OF VITAMIN B12‐REQUIRING MARINE DIATOMS IN MIXED LABORATORY CULTURES WITH VITAMIN B12‐PRODUCING MARINE BACTERIA 1 2

The vitamin B12 requirement of several marine diatoms can be satisfied in B12−limited laboratory cultures by heterotrophic marine bacteria isolated from the same waters and from sediments. The bacteria can utilize diatom excretory products, or the remains of dead diatom cells, in the production of the vitamin.
