The optimum concentration ratio of zinc and magnesium for co-production of bioethanol and pigments for Monascus purpureus

Zinc and magnesium were the essectial activators for bioenzyme. Here, we assayed single factor assays for the effect of zinc and magnesium for Monascus purpureus.Then, we carried out transcriptome assays to uncover molecular mechanism of the enhanced fermentability of bioethanol and pigments for M. purpureus under the optimal metal ion concentration.This work would provide the fermentation process for biofuels and biochemicals. Overall design: We performed gene expression profiling analysis using from RNA-seq data from two different mycelia at one time point for Monascus purpureus.
