摘要：

The importance of bioprocesses has increased in recent decades, as they are considered to be more sustainable than chemical processes in many cases. E factors can be used to assess the sustainability of processes. However, it is noticeable that the contribution of enzyme synthesis and purification is mostly neglected. We, therefore, determined the E factors for the production and purification of 10 g enzymes. The calculated complete E factor including required waste and water is 37,835 g(waste)center dot g(enzyme)(-1). This result demonstrates that the contribution of enzyme production and purification should not be neglected for sustainability assessment of bioprocesses.
