Alternariol and alternariol monomethyl ether are commonly associated with weathered grain sorghum. Production of these metabolites and altenuene by isolates of Alternaria alternata was evaluated on various sterile grain substrates. At 35% moisture content and 25 C, metabolite yields were highest on rice, intermediate on sorghums, and lowest on wheat and yellow corn. Fourteen-to 21-day cultures on milled rice were best in terms of ease of metabolite recovery, even though yields were higher on 28-day cultures of rough and brown rice. Metabolite production was reduced when rice was supplemented with yeast extract or yeast extract plus Czapek-Dox broth.
链格孢酚和链格孢酚单甲醚通常与陈化的高粱籽粒有关。在各种无菌谷物底物上评估了链格孢菌分离株产生这些代谢物和细交链孢菌酮酸的情况。在含水量35%和25℃条件下，水稻上的代谢物产量最高，高粱上的产量中等，小麦和黄玉米上的产量最低。就代谢物回收的难易程度而言，碾磨大米上培养14至21天的效果最佳，尽管糙米饭和糙米培养28天时产量更高。当在大米中添加酵母提取物或酵母提取物加察氏肉汤时，代谢物产量会降低。
