Polymorphonuclear proteolytic activity and milk composition change.
Relationships between Quarter Milk Cell Count (QMCC) and Tank Milk Cell Count (TMCC) with milk biochemical and technological parameters in milk and dairy products were investigated. All parameters measured were affected by the increase of TMCC and QMCC between 0 and 600 000 cells/mL. The variable effect of lactation stage which is different for different authors, is discussed. The three mechani...
متن کاملE. coli proteolytic activity in milk and casein breakdown.
Previous studies have focused on both LPS and E. coli experimental mastitis and underlined the respective roles of endogenous proteolysis (including plasmin from the blood stream and other proteases from milk leukocytes), as well as the presence of E. coli in a more intricate system. The aim of this study was to assess the role of E. coli in milk proteolysis and especially that of its proteases...
متن کاملScreening on Proteolytic Activity of Lactic Acid Bacteria from Various Yogurts and Fermented Milk
Proteases are necessary for living organisms; they are ubiquitous and found in a wide diversity of sources. Proteases are the key enzymes in industrial application. Microbial protease plays an important role in biotechnological process. In this paper the focus of this study is screening on Proteolytic activity of lactic acid bacteria from various yogurts and fermented Milk. Lactic acid bacteria...
متن کاملProteolytic and antimicrobial activity of lactic acid bacteria grown in goat milk
We examined 62 strains and 21 trade starter cultures from the collection of LB Bulgaricum PLC for proteolytic and antimicrobial activity of lactic acid bacteria (LAB) grown in goat milk. The aim of this study was to investigate the fermentation of caseins, α-lactalbumin and β-lactoglobulin by LAB, using the o-phthaldialdehyde (OPA) spectrophotometric assay and sodium dodecyl sulphate polyacryla...
متن کاملEffects of stage of lactation and time of year on plasmin-derived proteolytic activity in bovine milk in New Zealand.
The objective of this study was to determine the effects of stage of lactation (SOL) and time of year on plasmin-derived proteolytic activity in the milk of pasture-fed dairy cows in New Zealand. Four herds of 20 Friesian cows were used, one herd calving in each of January, April, July and October. Cows grazed ryegrass/white clover pasture only, except during June (winter) when all cows receive...
