We have previously reported that squalene overproducing yeast self-downregulate the expression of the ethanol pathway (non-essential pathway) to divert the metabolic flux to the squalene pathway. In this study. the effect of co-production of squalene and ethanol on other non-essential pathways (fusel alcohol pathway. FA) of Saccharomyces cerevisiae was evaluated. https://parisnaturalfoodes.shop/product-category/navy-beans/
