Table 1 Specific growth rate (μ), generation time, maximal bacterial abundance fold increase of four bacterial strains in AVFA and control (CTR) treatments during incubation in this study, and comparison with maximal % fold increase in AVFA incubations within 72 h based on DNA amplicon sequencing data from cited previous studies using natural bacterial assemblages.

  1. Note that the fold increase of bacterial abundance in this study may not be directly comparable to that from sequencing data from other studies as uneven gene copy numbers among bacteria were amplified for sequencing, thus interpretation should be in caution.
