Fig. 4From: Development of a novel, robust and cost-efficient process for valorizing dairy waste exemplified by ethanol productionOne representative ethanol fed-batch fermentation by JS122 on DWP under oxygen deprivation conditions. DWP contains 95 g/L lactose and 5 g/L galactose, and after 24 h and 48 h, 50 g/L of lactose was added. The cell density was 24 g/L CDWBack to article page
