Figure 3From: Use of a Tn5-based transposon system to create a cost-effective Zymomonas mobilis for ethanol production from lignocellulosesComparisons of ethanol production between three kinds of Z. mobilis strains in medium with different concentration of yeast extract. Strains were grown in medium (1 g/L KH2PO4, 1 g/L Carbamide, 0.5 g/L MgSO4.6H2O) with 230 g/L glucose as carbon source, supplemented with different amounts of yeast extract (as indicated) under anaerobic conditions at 32°C. All strains were tested by three parallel experiments. After 60 hours fermentation, ethanol production of all strains was measured immediately by GC.Back to article page
