Effects of pH and temperature on the continuous production of amylolytic enzymes by bacillus amyloliquefaciens MIR‐41
Bacillus amyloliquefaciens MIR‐41 produces three exocellular amylolytic enzymes: α‐amylase, pullulanase and α‐glucosidase. Physicochemical factors such as pH and/or temperature may affect the enzyme yield. Continuous culture at a dilution rate of 0.15 h−1 demonstrated that the maximum production of...
