Physico-chemical Properties of Brick Kiln Dust Amended Soils and Their Effect on Solanum Tuberosum
The study was conducted to analyze the physico-chemical properties of various levels of brick kiln dust in soil application (0, 5, 10, 15, 20, 25, 30, 40 and 50%), before planting and after harvesting of potato (Solanum tuberosum) crop and to observe their impact on various parameters of potato plant. The pH, EC, CEC, WHC, pore space, sulphate, chloride, phosphorus, magnesium, zinc, manganese a...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولStudies on the chemical modification and potato (Solanum tuberosum) lectin and its effect on haemagglutinating activity.
1. Modification of potato (Solanum tuberosum) lectin with acetic anhydride blocked 5.1 amino and 2.7 tyrosyl groups per molecule of lectin and decreased the haemagglutinating activity of the lectin. De-O-acetylation regenerated 2.0 of the tyrosyl groups and resulted in a recovery of activity. 2. Modification with citraconic anhydride or cyclohexane-1,2-dione did not greatly affect activity, alt...
متن کاملDistribution of zinc and copper chemical forms and their relationship with some physico-chemical properties and clay minerals in some calcareous soils
Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
