An RDA (redundancy analysis) triplot showing correlations among saeu-jeot samples, bacterial abundances, and metabolite concentrations during fermentation of saeu-jeot with 20%, 24%, 28%, and 32% salt concentrations.

<p>Numbers beside the symbols represent the fermentation time (days). The primary organic compounds and methylamines are highlighted in bold, and the directions and lengths of the straight arrows indicate their influences on the saeu-jeot samples. The curved arrow indicates the route of metabolite changes in saeu-jeot samples on the RDA triplot during saeu-jeot fermentation. Saeu-jeot samples inside the circle contained acetate, butyrate, TMA, and DMA as the major products.
