Spore production of Coniothyrium minitans during solid-state fermentation on different nitrogen sources with glucose or starch as carbon source
Sporulation of Coniothyrium minitans on 20 g glucose/l or 18 g starch/l at an initial C/N ratio of 10 was the lowest for nitrate and histidine (1 x 10(9) vs 5-6 x 10(9) spores/dish). At 100 g glucose/l or 90 g starch/l lower spore numbers as compared to the lower concentrations are obtained for all nitrogen sources tested; only the spore numbers with urea and glycine were equal with either 18 or 90 g starch/l. Spore numbers at 90 g starch/l were all a factor two or more higher than at 100 g glucose/l.
