4. Conclusion
Amylase assay showed maximum extracellular enzyme activity
of 538 U/ml. Optimum parameters were identified in
submerged fermentation which was carried out in a 5 L
fermentor with a working volume of 3.5 L and the maximum
protein content was estimated to be 2.72 mg/L. Ammonium
sulfate precipitation was performed to partially purify the
fermented product and it showed maximum protein content
of 54.54 mg/L which is about 80% higher than non purified
enzyme. The SSII2 isolate was characterized by 16S rDNA
sequencing and found to be B. subtilis. The partially purified
protein can be further characterized by SDS-PAGE analysis
and column chromatography. By doing so, a stable amylase
with higher enzyme activity can be identified which may have
