Alkaline Protease Gene

Bacillus alcalophilusisolated was used for the production of alkaline protease. The enzyme encoded by alkaline protease gene (apr4) gene. To further improve the production of the strain for industrial requirement, a genetic manipulation system forBacillus alcalophiluswas developed. Additional copies of theapr4 gene were transferred into the strainBacillus alcalophilusand integrated into the 16S rDNA sites, yielding a series of recombinant strains. One of these recombinant strains, designated K23, exhibited superior properties for production of alkaline protease. the protease activity of K23 achieved by (6.19 ± 0.34) × 104U/ml, which is approximately 111.3% higher than that of the wild-type ones for 50-h fermentation. In addition, the new strain was genetically stable for more than 100 generations. These superior characteristics make it to be more suitable than the wild-type strain for alkaline protease production.
