This study investigated the effect of high pressure homogenization (HPH) (up to 190 MPa) on porcine pepsin (proteolytic and milk-clotting activities), and the consequences of using the processed enzyme in milk coagulation and gel formation (rheological profile, proteolysis, syneresis, and microstructure). Although the proteolytic activity (PA) was not altered immediately after the HPH process, ...

in the present work, a new branch of biotechnological advantage of the latex of an endemic perennial plant, euphorbia microsciadia has been introduced. a novel cysteine protease, designated as microsciadin, was purified from the latex of euphorbia microsciadia by a combination of sequential usage of sp-sepharose fast flow column in two different phs and a final gel filtration chromatography. mi...

Studies on the extraction of milk-clotting enzyme after solid-state fermentation (SSF) of wheat bran by a local strain of Aspergillus oryzae LS1 were done. The extraction of the enzyme was found to be depended on different parameters like nature of extractant, soaking time, temperature etc. From different inorganic and organic extractants, calcium chloride (0.05%) and glycerol (40%) were found ...

Carboxyl groups i n porcine pepsin were chemically modified "by the carbodiimide reaction using waterrsoluble l-ethyl-3-(3-dimethylaminopropyl) carbodiimide and amino acid esters as nucleophiles. The modification resulted in profound changes in the a c t i v i t i e s , specificity and.some physicochemical properties of the enzyme. These include* (1) significant decrease in milk clotting activi...
