Are any of you assessing the environmental sustainability of biorefineries using SimaPro? Is there any database with the most suitable data for yeast and enzymes? For yeast, Ecoinvent has Fodder Yeast but in my opinion it is not suitable since it does not represent the impacts of Saccharomyces cerevisiae. And in the case of enzyme, the database Agribalyse has gluco-amylase with empty values which does not help at all.

Could you please tell me what is the best methodology to evaluate the impacts of these two elements?
