Ethanol production by K. marxianus DSMZ 5422 (a) and S. cerevisiae Ethanol Red (b) in the SSF processes. Y axis: ethanol concentration in g/L. X axis: time of the SSF process in h. Closed circles—SSF control culture variants in which only yeast cells were provided, without any amylolytic agent; open circles—SSF culture with AMY + GlucoAMY enzymatic preparation used as the amylolytic agent; closed triangles—SSF culture with Stargen enzymatic preparation used as the amylolytic agent.
