Fig. 3From: A temperature dependent pilin promoter for production of thermostable enzymes in Thermus thermophilusGrowth-phase dependent β-glucosidase activities in cells. Shown are the optical density (•) and β-glucosidase activities (bars) of T. thermophilus ΔbglT (pMKE2-PpilA4-499) cells grown in TM+-medium at 68 °C (A), 80 °C (B) or in minimal medium with 20 mM pyruvate as carbon and energy source at 68 °C (C) or 80 °C (D)Back to article page
