Growth profiles of A. niger DS03043 during fed-batch cultivation (Arrows represents four sampling time points at 16, 24, 42, and 66 h). a Online data of DO and OUR. After the dotted line, it came into the oxygen limitation stage; b off-line data of μ and qp; c the yield of glucoamylase to biomass; d the changes of dry weight; e enzyme activity of glucoamylase. All parameters were measured based on triplicate measurements
