S sp. D1 and S. gulbargensis, respectively, in the presence of Co2+ ions. The uncommon behavior in the enzymes for Co2+ ions could possibly be related to its specific structure and also the mechanism of action behind this is topic to additional research. Metal ions such asFigure two: Impact of different incubation periods on enzyme activity (at 55 C for -amylase).61.33 and 43.26 , respectively. Enzyme-substrate reaction was maximally active in the range of ten min to 50 min (80 relative activity) with maximum -amylase activity accomplished in 30 min at 55 C (Figure two). There was a remarkable reduce in -amylase activity soon after 50 min incubation. The enhance in incubation period might induce conformational changes in 3D structure of the enzyme affecting its substrate affinity. Chakraborty et al. [18] reported a drastic decrease in amylase activity at 90 C with maximum activity at 50 C from Streptomyces sp. D1. Syed et al. [19] reported optimal activity at 45 C for -amylase from S. gulbargensis. Benefits from present study present lines of evidence that -amylase from Streptomyces sp. MSC702 could possibly be a good candidate for the effective liquefaction of gelatinized starch. The optimum pH for -amylase activity from Streptomyces sp.Enoxaparin MSC702 ranged from pH 3.0 to 7.0 (retained 91 activity) with a maximum activity at pH 5.0 (Figure three). Though a decline in enzyme activity was observed involving pH eight.0 and pH 9.0, the enzyme was nevertheless active at pH eight.0 and 9.0, retaining its 52.71 and 34.78 activity. A total loss within the enzyme activity was observed above pH 9.eight. Activity of -amylase at low pH range is quite crucial for industrial applications [20]. The application of liquefying amylases which might be active and stable around the saccharification pH isTable 1: Comparative analysis on the impact of various additives on enzyme stability.
