Microbiology: Algae and the vitamin mosaic
Robert A. Andersen1
Abstract
The requirements for vitamin B12 vary among algal species in a seemingly inexplicable pattern. A study that exploits genomic data now provides enlightenment — and evidence of symbioses with bacteria.
Animals require vitamin B12 in their diets but plants don't. Algal requirements, on the other hand, present a complicated picture.
