2.1. Extractive fermentation for production of extracellular yellow
Monascus pigments
Monascus anka (China Center of Industrial Culture Collection,
CICC 5013) was used in this study. Production of extracellular
Monascus pigments by extractive fermentation in the nonionic surfactant
Triton X-100 micelle aqueous solution followed the same
procedure as described in our previous work [16]. Yellow
Monascus pigments as well as orange Monascus pigments were
accumulated in the extracellular nonionic surfactant micelle aqueous
solution. The detailed information was presented in supplementary
materials of Fig. S1.
