Studies on the production of milk-clotting enzymes, proteolytic enzymes and mucilage by fungi.
Of 48 fungal isolates, 28 (including one Penicillium and three Aspergilli) secreted milk-clotting enzymes. This activity was in general related to the mycelial growth of a given isolate, but not with pH change of the culture filtrate during incubation. It was not found when mucilage was formed by isolates capable of doing so. The ratio of general proteolytic activity to milk-clotting activity v...
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...
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 کاملProteolytic Activity and Some Properties of Stirred Fruit Yoghurt Made Using Some Fruits Containing Proteolytic Enzymes
Stirred yoghurts with different fruit homogenates (papaya, kiwi, pineapple and kaki and control (without additive) were prepared and stored up to 14 days at 5±1°C. Sugar and fruit homogenates were added at the rate of 5 and 10% w/w respectively. The results revealed that, significant differences were observed in proteolytic activity, acidity, protein and fibers contents among all treatments. Ad...
متن کاملProteolytic and Milk Clotting Activity of Fractionated Protein of Lagenaria siceraria
Article history: Received on: 14/10/2015 Revised on: 04/11/2015 Accepted on: 15/11/2015 Available online: 27/12/2015 The study was undertaken to evaluate milk clotting and proteolytic activity of protein fractions of seeds of Lagenaria siceraria. Protein fractions were isolated by the method of differential solubility, and their protein contents were estimated using Bio-Rad protein assay reagen...
