Fig. 8From: Effects of branched-chain amino acids on Shiraia perylenequinone production in mycelium culturesThe time-course of fungal biomass (A), HA content in mycelium (B), the released HA in cultural broth (C) and total HA production (D) in submerged culture of S. bambusicola S8 treated by l-Val. Total HA production refers to the sum of the intracellular and extracellular HA. The fungus was treated with l-Val (1.5 g/L) on day 2. The culture untreated with l-Val in the production medium with Triton X-100 was used as control. Values are mean ± SD from three independent experiments (*p < 0.05, **p < 0.01 versus control group)Back to article page
