Abstract
In this work, the gene of ?-amylase from B. subtilis was cloned and expressed in Non-amylase produsing E.coli. B. subtilis was isolated by performing various biochemical tests. The organism producing ?-amylase enzyme was successfully isolated. The isolation of genomic DNA followed by amplification of Gene Of Interest using ?-amylase primer and annealing temperature 56°C was done using PCR technique. The amplified product was eluted from electrophoresis gel and subjected to restriction digestion (EcoRI) and then ligation with the vector (Plasmid DNA pUC18). A competent cell was prepared using chemical method (CaCl2). The ligation mixture was allowed to react with the competent cells in order to produce transformed cells producing ?-amylase enzyme. The mixture was spread over the starch plates. The successfully transformed E.coli cells were observed over the Starch agar plate.
