Fig. 5From: Production of spiculisporic acid by Talaromyces trachyspermus in fed-batch bioreactor cultureEffect of initial pH on spiculisporic acid production by T. trachyspermus NBRC 32238. The medium was adjusted to an initial pH of 2.0–4.0, and the strain was cultured with 100 g/L glucose at 28 °C for 7 days. Error bars indicate standard deviations from three independent experimentsBack to article page
