Figure 3: Thermal stability of Streptomyces misionensis PESB-25 endoglucanase activity at 65°C (- -) and 50°C (—): crude extract (filled diamond), crude extract + MnSO4 8 mM (filled triangle), and crude extract + MnSO4 16 mM (filled circle). Residual activity is expressed as a percentage of the original activity. Error bars represent one standard deviation of each experimental point ( ).
