Fig. 8From: Production of spiculisporic acid by Talaromyces trachyspermus in fed-batch bioreactor cultureEffect of trace metal ions on spiculisporic acid production by T. trachyspermus NBRC 32238. a Comparison of spiculisporic acid production with various metal compounds. b Spiculisporic acid production with FeCl3 at concentrations of 0–50 g/L. Cultivation was carried out with 100 g/L glucose at 28 °C for 7 days. Error bars indicate standard deviations from three independent experimentsBack to article page
