Milk-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...
متن کاملUtilization of salt whey from Egyptian Ras (cephalotyre) cheese in microbial milk clotting enzymes production.
BACKGROUND Microbial milk-clotting enzymes are valued as calf rennet substitutes in the cheese industry. The worldwide increase of cheese production coupled with a reduced supply of calf rennet has prompted a search for calf rennet substitutes, including microbial and plant rennets. However, most plant rennets have proved unsuitable because they impart a bitter taste to the cheese. Microbial re...
متن کاملComparing the Activity and Thermal Inactivation Behavior of Lactoperoxidase in Iranian Cow and Buffalo Milk and Whey
Background: Lactoperoxidase (LPO) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. The aim of this study was to provide information on activity and thermal inactivation behavior of LPO in Iranian cow and buffalo milk and whey. Methods: Sixty cow and buffalo milk samples were collected. The LPO activity was measured using ...
متن کاملThermal inactivation of Yersinia enterocolitica in milk.
Three strains of Yersinia enterocolitica isolated from milk had D values at 62.8 degrees C from 0.24 to 0.96 min and z values of 5.11 to 5.78 degrees C. Since the pasteurization processes for dairy products recommended by the Food and Drug Administration are adequate to destroy large concentrations of these organisms, Y. enterocolitica in pasteurized milk probably results from substandard proce...
