Both enantiomers of the sulfoquinovose breakdown product 2,3-dihydroxypropane-1-sulfonate, an important sulfur metabolite produced by marine algae, were synthesised in a S-labelled form and used in feeding experiments with marine bacteria. The labelling was efficiently incorporated into the sulfur-containing antibiotic tropodithietic acid and sulfur volatiles by the algal symbiont Phaeobacter inhibens, but not into sulfur volatiles released by marine bacteria associated with crustaceans. The ecological implications and the relevance of these findings for the global sulfur cycle are discussed.
磺基奎诺糖分解产物2,3 - 二羟基丙烷 - 1 - 磺酸盐是海藻产生的一种重要硫代谢物，其两种对映体均以S标记形式合成，并用于海洋细菌的投喂实验。藻类共生体抑制性费氏杆菌能将这种标记有效地整合到含硫抗生素杀鱼菌素和硫挥发物中，但不能整合到与甲壳类动物相关的海洋细菌释放的硫挥发物中。本文讨论了这些发现对全球硫循环的生态意义及相关性。
