Fig.Ā 1From: Production and characterization of yeasts grown on media composed of spruce-derived sugars and protein hydrolysates from chicken by-productsGrowth of four yeast strains in the Duetz-MTPS system using 10 different media. The graphs show CDW (g/L) after 24Ā h cultivation (values are meanāĀ±āSD; nā=ā3), whereas Additional file 1: Figs. S1 and S2 provide more complete growth curves and pH profiles. Conditions: Glucose, 50Ā g/L; Kjeldahl nitrogen, 5.86Ā g/L; ODinitialā=ā0.5; volume: 2.5Ā mL; pHinitial=ā5.0; incubation at 30Ā Ā°C with 450Ā rpm shaking. The pH and pO2 were not controlled and several of the apparent differences between media may be due to buffering effects.
