Production of HA (a) and iso-HA (b) in different media amended with tomato plant tissue. PDB = full PDB (-♦-); PDB 1/5 = 1/5 strength PDB (-▲-); PDB + plant tissue = full PDB amended with tomato plant tissue (-■-); PDB 1/5 + plant tissue = 1/5 strength PDB emended with tomato plant tissue (-x-); SM = salt medium with 1% glucose (-●-). Each point on the line is the mean ± the standard deviation of four independent biological replicates. Point on the line with the same letter are not significantly different; point on the line without the letter are significantly different (p < 0.05).
