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 کاملThe Milk-clotting Action of Papain*
Although the milk-clotting action of papain has been recognized for many years, this property of the enzyme has received little quantitative attention. It appears to be, however, a characteristic property of the proteolytic component of this enzyme system. Various workers have brought forth evidence as to the composite nature of the papain system, which has at least two components. In the most ...
متن کاملClxxxv. the Action of Thyroxine on the Milk and Milk-fat Production of Cows. by William
A PREVIOuS study of the effects of thyroidectomy and thyroid feeding on the lactation of cows has shown that the thyroid gland has a marked influence on the production of milk and milk-fat by the cow [Graham, 1934]. Rises in milk and milk-fat production were shown when desiccated thyroid glands were added to the diet either of thyroidectomised animals or normal animals which were past the peak ...
متن کاملStudies 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 کاملthe effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows
پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
