Purification and Characterization of Milk Clotting Enzyme Produced by Rhizomucor Rmiehei
Milk clotting enzyme (M CE) produced by: Rhizomucor miehei was purified and characterized.The enzyme was purified 220.29-fold with specific activity about 14444.2 U/mg protein byultrafiltration, ammonium sulfate fractionation, Sephacryl S-300 chromatography. The maximumenzyme activity was at 65°C.The milk clotting activity was decreased steadily as pH is increased and indicated maximumactivity ...
متن کاملCloning and expression of clt genes encoding milk-clotting proteases from Myxococcus xanthus 422.
The screening of a gene library of the milk-clotting strain Myxococcus xanthus 422 constructed in Escherichia coli allowed the description of eight positive clones containing 26 open reading frames. Only three of them (cltA, cltB, and cltC) encoded proteins that exhibited intracellular milk-clotting ability in E. coli, Saccharomyces cerevisiae, and Pichia pastoris expression systems.

متن کاملCharacterization of partially purified milk‐clotting enzyme from sunflower (Helianthus annuus) seeds
This study was aimed to extract milk-clotting enzyme from sunflower seeds and to determine its potentiality for manufacturing white soft cheese from cows and goats milk. The seeds were blended and extracted using two types of buffers and milk-clotting and proteolytic activities were evaluated. The enzyme was partially purified using ammonium sulfate fractionation techniques. Results indicated t...
متن کاملMilk-clotting Enzymes from Microorganisms.
A total of 230 cultures of fungi and 43 cultures of bacteria, isolated from such sources as soil, butter, and milk, were screened for their milk-clotting activity. The fungi were cultivated on semisolid media, and the bacteria were grown in milk media in shake culture. Phytic acid, added as calcium phytate, was found to stimulate production of the enzyme in most of the bacterial isolates. Prote...
