Studies on Alkaline Protease Production from Bacillus sp
The aim of this study was optimization of the conditions for the production of alkaline protease from the Bacillus strains coded as L18, L21 and I18, which were isolated from our natural habitats. Additionally, the goal was also to optimize the production of alkaline protease from Bacillus sp. L21 in a new low-cost media formulation by employing design of experiments and response surface method...
متن کاملCharacterization Studies on Caseinolytic Extracellular Alkaline Protease from a Mutant Bacillus Licheniformis
After our previous purificational and optimisational studies on alkaline protease from a mutant of B. licheniformis Bl8, Characterisation of the purified enzyme was done from the culture supernatant by employing various parameters. The optimum pH and temperature for the activity of alkaline protease was previously found to be 10 and 50 0 C and stable in the pH range 5.0-12.0. The thermo stabili...
متن کاملPhysiological and Microbiological Studies on Production of Alkaline Protease from Locally Isolated Bacillus Subtilis
In this study, we have shown the microbial alkaline protease production by using isolated Bacillus subtilis. Bacillus subtilis which produces an extracellular alkaline protease was isolated from meet surface purchased from local Egyptian markets. Maximum enzyme activity was achieved when the bacterium was grown on corn steep liquor (2.0 %, w/v) instead of soybean meal (2 %) followed by casein h...
متن کاملStudies on alkaline serine protease produced by Bacillus clausii GMBE 22.
An alkali tolerant Bacillus strain having extracellular serine alkaline protease activity was newly isolated from compost and identified as Bacillus clausii GMBE 22. An alkaline protease (AP22) was 4.66-fold purified in 51.5% yield from Bacillus clausii GMBE 22 by ethanol precipitation and DEAE-cellulose anion exchange chromatography. The purified enzyme was identified as serine protease by LC-...
متن کاملStudy on Preparation of Immobilized Alkaline Protease and Its Performance
The nano-Fe3O4 particles were prepared by hydrothermal method. Cellulose-based magnetic Fe3O4 was prepared by adding cellulose solution dissolved in sodium hydroxide / thiourea / urea system. The basic protease was used as the catalyst and glutaraldehyde was used as the crosslinking agent, The production of magnetic recyclable immobilized enzyme can greatly reduce the cost of hydrolysis of slud...
