Summary: This study investigated the production of natural pigments by five filamentous fungi isolated from soil and cultured on a mixture of green waste and whey. Optimal conditions for pigment production were found to be at pH 7.0 and 9.0, with higher biomass and pigment intensities observed in solid-state fermentation compared to submerged fermentation. The study suggests that solid-state fermentation may be a feasible strategy for scaling up pigment production in manufacturing industries.

Summary: Cordycepin production was enhanced by modifying glycolysis and pentose phosphate pathway in engineered Yarrowia lipolytica. The production of cordycepin from economical and renewable substrates was analyzed, and the effects of C/N molar ratio and initial pH were evaluated. The maximum cordycepin productivity achieved in the optimized medium was 656.27 mg/L/d (72 h) and the cordycepin titer was 2286.04 mg/L (120 h) by engineered Y. lipolytica. The cordycepin productivity in the optimized medium increased by 28.81% compared to the original medium. This research establishes a promising way for efficient cordycepin production from agro-industrial residues.
