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...
متن کاملIsolation, 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...
متن کاملcloning 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...
متن کاملImmobilization of Neutral Protease from Bacillus subtilis for Regioselective Hydrolysis of Acetylated Nucleosides: Application to Capecitabine Synthesis.
This paper describes the immobilization of the neutral protease from Bacillus subtilis and its application in the regioselective hydrolysis of acetylated nucleosides, including building blocks useful for the preparation of anticancer products. Regarding the immobilization study, different results have been obtained depending on the immobilization procedure. Epoxy hydrophobic carriers gave a poo...
متن کاملNMR Analysis of Sulfonated Polystyrene
Atactic polystyrene (PS) has an amorphous structure. Compounds such as H2SO4 and SO3 are commonly used as sulfonating agents for various polymers, including PS. The main purpose of this work is to study chemical structural changes in PS arising from sulfonation through DSC analysis and NMR spectroscopy. An increase in the glass transition temperature (Tg) of sulfonated polystyrene and a decreas...
