Effects of zinc, iron, cobalt, and manganese on Fusarium moniliforme NRRL 13616 growth and fusarin C biosynthesis in submerged cultures.
The influence of zinc, iron, cobalt, and manganese on submerged cultures of Fusarium moniliforme NRRL 13616 was assessed by measuring dry weight accumulation, fusarin C biosynthesis, and ammonia assimilation. Shake flask cultures were grown in a nitrogen-limited defined medium supplemented with various combinations of metal ions according to partial-factorial experimental designs. Zinc (26 to 3...
متن کاملGlucose and zinc concentration influence fusarin C synthesis, ethanol synthesis and lipid composition in Fusarium moniliforme submerged cultures.
A fusarin C-producing Fusarium moniliforme strain was grown in submerged culture with defined media containing differing amounts of glucose (30 g/l or 90 g/l) and zinc (5 ppb or 3200 ppb). The influence of zinc on fusarin C synthesis and lipid composition was dependent on the initial glucose concentration. In cultures supplied with 30 g/l glucose, zinc inhibited fusarin C and lipid synthesis by...
متن کاملProduction of fumonisin B1 by Fusarium moniliforme NRRL 13616 in submerged culture.
Fumonisin B1, a recently discovered mycotoxin, was synthesized by submerged cultures of Fusarium moniliforme NRRL 13616 grown for 29 days at 28 degrees C and 220 rpm in a basal salts medium (pH 5.0) supplemented with 90 g of glucose per liter and 3.5 g of ammonium sulfate per liter. Under these culture conditions, 74 +/- 23 micrograms of fumonisin B1 per ml was produced by 29-day-old F. monilif...
متن کاملGlucose and zinc concentration influence fusarin C synthesis, ethanol synthesis and lipid composition in Fusarium moniliforme
A fusarin C-producing Fusarium monilifomle strain was grown in submerged culture with defined media contaIning differing amounts of glucose (30 gil or 90 g/l) and zinc (5 ppb or 3200 ppb). The influence of zinc on fusarin C synthesis and lipid composition was dependent on the initial glucose concentration. In cultures supplied with 30 gil glucose, zinc inhibited fusarin C and lipid synthesis by...

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
