Abstract
Many microalgae acquire vitamin B12 from marine prokaryotes. A new study demonstrates that vitamin B12 is synthesized by planktonic cyanobacteria as pseudocobalamin, a form not bioactive in microalgae. However, some microalgae can remodel pseudocobalamin to the active cobalamin form, adding complexity to our assessment of active vitamin B12 in the environment.
摘要
许多微藻从海洋原核生物中获取维生素 B12。一项新的研究表明，浮游蓝细菌合成假钴胺素形式的维生素 B12，这种形式对于微藻没有生物活性。然而，一些微藻可以将假钴胺素重塑为活性钴胺素形式，这为我们评估环境中活性维生素 B12 的复杂性增添了新的内容。
