From: Process development for the elucidation of mycotoxin formation in Alternaria alternata

Carbon source Nitrogen source AOH [mg/L] AME [mg/L] TA
[mg/L]
Process time [h] BDM [g/L]
aGlucose NH4Cl, NaNO3 3.49 ± 0.121 1.62 ± 0.142 38.28 ± 1.61 260 3.3 ± 0.1
aGlucose Aspartic acid 7.75 ± 0.064 4.81 ± 0.014 36.54 ± 0.81 350 3.49 ± 0.27
bNa-acetate NH4Cl, NaNO3 6.64 ± 0.010 ND ND 400 1.98 ± 0.06
Na-acetate Aspartic acid 3.66 ND ND 400 2.62
  1. a Results are mean of 5 replicates ± standard deviation
  2. b Results are mean of 2 replicates ± standard deviation.
  3. Acetate fermentations were conducted without pH control, glucose fermentations were performed at pH 5.5. Values display maximal detected mycotoxin concentration. Process time gives the earliest time point when the maximum concentration was achieved.
  4. AOH: alternariol; AME: alternariol monomethylether; TA: tenuazonic acid; BDM: biodrymass; ND: below detection limit of < 0.001 mg/L.
