Yeast screening and cell immobilization on inert supports for ethanol production from cheese whey permeate with high lactose loads
Fig 5
Evolution of ethanol concentration employing K. marxianus DSM 5422 on inorganic supports [glass Raschig rings (GRR) and alumina beads (AB)] during 14 fermentation cycles (Li = 130 g/L).
Asterisks indicate the existence of significant differences (p < 0.05) between supports for a given batch.
