wPercentage increase of a growth variable by bacterial treatment compared to the control. xGSF = growth stimulation frequency; frequency at which a strain increased growth (at 95% confidence level) in all measurements across trials. Significant difference between treatment and control () according to Dunnett’s test. — = no data because strain was not tested.
