“…Contradictory data would be compatible with causative agents such as mycotoxins, the levels of which in agricultural products vary greatly from place to place and from one year to another, depending on the prevailing weather conditions (Stoloff, 1976;Mirocha, 1976;Hacking et al, 1976;Martin, 1981;Sutton et al, 1980;Buckle, 1983). Cereal grains in particular, if inappropriately dried after wet harvest become mouldy and favour the production of mycotoxins.…”

Among the many already known mycotoxins, the ones most relevant as health hazards in Great Britain, and in other Countries in the temperate zones, are the secondary metabolites of Fusaria. These common moulds (often pink) can produce in stored highmoisture agricultural products, the oestrogenic, non-steroidal, zearalenone and/or T-2 toxin, and other irritant trichothecenes.Significant levels of such mycotoxins may develop in cereal-grains harvested under very wet weather conditions, or when imported by sea.

“…In Great Britain, the surveillance of human food and animal feedstuffs for the presence of the relevant Fusarial mycotoxins, such as zearalenone and the trichothecenes, the estimation of which is complicated· and requires expensive apparatus, has been only fragmentary (Hacking, 1976;Buckle, 1983;Gilbert et al, 1983).…”

“…Zearalenone-and trichothecene-producing Fusarium species have been found in wheat (Hagler et al 1984) barley (Hacking et al 1976), sorghum (Schroeder and Hein 1975), maize (Caldwell and Tuite 1970), and mixed feed (Mirocha et al 1976), especially in grains. The main ingredient in corn, up to 70% of the fresh weight, is starch.…”

To raise the yields for the production of 14C-labelled zearalenone in Fusarium cultures the influence of growth conditions and known effectors or precursors of toxin biosynthesis was studied. Benzoic acid and 2,4-dihydroxybenzoic acid used as precursors decreased toxin formation; in the presence of different pesticides such as 2,4-dichlorophenoxyacetic acid, however, toxin production increased up to 140%. The known pathway of zearalenone biosynthesis could be confirmed from the relative extents of 13C-incorporation into the zearalenone molecule by incubating Fusarium 9raminearum DSM 4529 with D-(+)-[1-~3C]glucose as carbon source. When grown in the presence of D-[U-14C]glucose or [2-~4C]malonic acid the strain produced [14C]zearalenone with specific activities of 0.07 and 0.09 ~tCi/mg, the ~4C-incorporation rates being 0.34% and 0.48%, respectively.

“…Fusarium head blight (FHB), is a fungal disease that affects small grain cereals such as wheat, barley, and some forag grasses 1, 2. FHB is caused by fungi belonging to the genus Fusarium such as Fusarium graminearum , F. pseudograminearum , F. culmorum , F. poae , and F. avenaceum (for a recent review see 3).…”

“…FHB is caused by fungi belonging to the genus Fusarium such as Fusarium graminearum , F. pseudograminearum , F. culmorum , F. poae , and F. avenaceum (for a recent review see 3). FHB affects both yield and quality and in the most severe cases mycotoxins produced by the pathogen leads to contaminated grains and harvests have to be discarded 1, 2.…”

We investigated the growth behavior and amylolytic enzymes of Fusarium graminearum cultivated on different types of native starch granules including barley (A‐type crystalline polymorph), potato and Curcuma zedoaria (B‐type crystalline polymorph), cassava (C‐type crystalline polymorph), and high AM maize (A + Vh‐type crystalline polymorphs). F. graminearum grew poorly on B‐type starches and the accumulation of biomass was similar to that obtained for fungi cultivated under carbohydrate starvation conditions. In comparison, three‐ to fivefold higher accumulation of fungal biomass was observed for growth on the A‐, C‐ and A + Vh‐type starches. Fungal glucoamylase and α‐amylase activity increased over time in the presence of native starch granules. Interestingly, resistant B‐type starches induced the highest amylolytic activity indicating that F. graminearum interacts with B‐type granules although only limited degradation occur. Starch degradation products maltose and malto‐oligosacharides was found to increase glucoamylase and α‐amylase activity, whereas glucose acted as a catabolite repressor.
