Changes in Wheat Nutritional Content at Elevated [CO] Alter Growth and Mycotoxin Production on Grain.

Rising atmospheric [CO] has been shown to impact plant primary metabolism and the severity of head blight (FHB) in wheat. In this study, we evaluated how changes in grain nutritional content due to growth at elevated [CO] affected growth and mycotoxin production. Susceptible (Norm) and moderately resistant (Alsen) hard spring wheat grains that had been grown at ambient (400 ppm) or elevated [CO] (800 ppm) were independently inoculated with two fungal strains, which produce the trichothecene mycotoxin, deoxynivalenol.

Factors Affecting Production of Itaconic Acid from Mixed Sugars by Aspergillus terreus.

Itaconic acid (IA; a building block platform chemical) is currently produced industrially from glucose by fermentation with Aspergillus terreus. In order to expand the use of IA, its production cost must be lowered. Lignocellulosic biomass has the potential to serve as low-cost source of sugars for IA production.
