Some Nutritional Factors Affecting Production of Biomass and Antifungal Metabolites of Coniothyrium minitans

摘要: The ability of the mycoparasite Coniothyrium minitans to utilize a range C and N sources vitamins for growth, pycnidial formation antifungal metabolite production was examined using defined liquid medium. able use all tested, with exception D -xylose, although growth generally better on organic rather than NO 3 -N. Increasing C:N ratios from 9:1-202:1 constant (2.0 g L -l -alanine) resulted in steadily increasing yields, whereas (40.0 -glucose) gradually decreased yield. Addition thiamine glucose-alanine basal medium greatest increase but biomass still less that achieved an undefined molasses-yeast Pycnidial low or failed occur + absence vitamins, addition consistently led abundant format...
