Summary of the metabolites assigned in this study using a combination of multiple pulse programs (see text for details). Metabolites were products of ¹³C₆–glucose transformed by a natural aquatic bacterial community during a 2-day incubation of a seawater sample collected from a coastal location (Experiment 1). Colors: amino acids: red; dipeptides: orange; carboxylic acids: brown; nucleosides and nucleobases: green; carbohydrates: blue; amino alcohols: purple.
