Fig. 3From: Efficient de novo production of bioactive cordycepin by Aspergillus oryzae using a food-grade expression platformInfluence of adenine concentration on cordycepin production by the AoCordy-T1 transformant. The cordycepin titer (solid line) and residual adenine (dash line) concentrations in the fermented broth (A) and the biomass titer (A) at different cultivation times are shown. The fungal cultures were grown in SM medium containing different concentrations of adenine (0.5–2.0 g/L) and were incubated at 30 °C with shaking at 200 rpm. The culture without adenine supplementation was used as a control. All data are presented as mean values with standard deviation (SD)Back to article page
