Table 2 Comparison of deoxynivalenol (DON) concentration in ground grain versus distillers dried grains with solubles (DDGS) from fermentation with Ethanol Red

From: Conversion of deoxynivalenol to 3-acetyldeoxynivalenol in barley-derived fuel ethanol co-products with yeast expressing trichothecene 3-O-acetyltransferases

Barley line/cultivar Ground grain, mean ppm ±

Ethanol Red DDGS
(no galactose), mean ppm ±

Times DON concentrated in DDGS1
VA06H-252 129.5 ± 14.0 212.9 ± 3.0 1.6
VA04B-1253 118.3 ± 10.4 207.1 ± 3.0 1.8
Thoroughbred3 26.7 ± 1.3 130.9 ± 2.4 4.9
Price3 17.7 ± 0.5 99.4 ± 3.5 5.6
Eve2 2.8 ± 0.3 23.0 ± 0.3 8.2
  1. 1The concentration of DON in the DDGS was 1.6 to 8.2 times that in the original starting grain.
  2. 2Hulless genotype.
  3. 3Hulled genotype.
