Alkaline Protease from Bacillus firmus 7728

Isolation, Purification and Characterization of a Thermophilic Alkaline Protease from Bacillus subtilis BP-36

The goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native Iranian microorganisms. At the end of screening program, a Bacillus subtilis BP-36 strain producing thermophilic alkaline protease was isolated from a hot spring in Ardebil province. The target enzyme was purified using a one-step Aqueous two-phase systems (ATPS) prot...

cloning of alkaline protease gene from bacillus subtilis 168

the aim of this study was to clone the serine alkaline protease-encoding gene from bacillus subtilis 168. this protease, which can have many applications especially in detergent, may be industrially an important enzyme. for the amplification of the gene, pcr was performed with a pair of primers specifically designed for this purpose. electrophoresis of the pcr product showed the expected band o...

Isolation and Identification of an Alkaline Protease Producing Bacillus from Soil

Cloning and Enhanced Expression of an Extracellular Alkaline Protease from a Soil Isolate of Bacillus clausii in Bacillus subtilis

in the detergent industry. In this study, the extracellular alkaline serine protease gene, aprE, from Bacillusclausii was amplified by PCR and further cloned and expressed in B. subtilis WB600 using the pWB980 expression vector. Protease activity of the recombinant B. subtilis WB600 harboring the plasmid pWB980/aprEreached up to 1020 U/ml, approximately 3-folds higher than the nativ...

Optimization of Extracellular Alkaline Protease Enzyme from Bacillus Sp

Proteases are very important industrial enzymes, which contribute about 60% of the total world enzyme market. Among the various proteases, bacterial proteases are the most significant, compared with animal and fungal proteases (Rahman et al., 1994) and among bacteria, Bacillus sp are specific producers of extra-cellular proteases (Coolbear et al., 1992; Banerjee et al., 1999). These enzymes hav...
