Clostridium thermohydrosulfuricum 39E produced a cell-bound α-glucosidase. It was partially purified 140-fold by solubilizing with Triton X-100, ammonium sulfate treatment, DEAE-Sepharose CL-6B, octyl-Sepharose and acarbose-Sepharose affinity chromatography. The optimum temperature for the action of the enzyme was at 75°C. It had a half-life of 35 min at 75°C, 110 min at 70°C and 46 h at 60°C. The enzyme was stable at pH 5.0–6.0 and had an optimum pH at 5.0–5.5. It hydrolyzed the α-1,4-linkages… CONTINUE READING
