A Novelistic Biomaterial from Natural Source: its Isolation and Physico-Chemical Characterization

extraction 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 ...

Humic acid from Shilajit – a physico-chemical and spectroscopic characterization

Shilajit is a blackish–brown exudation, consisting of organic substances, metal ions and minerals, from different formations, commonly found in the Himalayan region (1000–3000 m) from Nepal to Kashmir. Shilajit can also b e collected t hroughout the mountain region s i n Afghani stan, Bhutan, China, Bajkal, throughout Ural, Cauc asus and Altai mountains also, at altitudes be tween 1 000 to 5000...

Chloropolysporins A, B and C, novel glycopeptide antibiotics from Faenia interjecta sp. nov. II. Fermentation, isolation and physico-chemical characterization.

New antibiotics, chloropolysporins A, B and C, were found in the culture broth of an actinomycete identified as Faenia interjecta sp. nov. They were isolated from the culture filtrate by column chromatography on various resinous adsorbents, followed by preparative reverse phase HPLC. Chloropolysporins A, B and C possessed all the same new aglycone composed of actinoidic acid, 3-chloro-4-hydroxy...

Physico-chemical Characterization of the Textile Dye Effluent and Isolation of Lignin Degrading Fungi Physico-Chemical Characterization of Textile Dye Effluent

Isolation and development of wheat based gluten edible film and its physico- chemical properties

Two Indian wheat cultivars viz. C-306 and RAJ-3765 were used for gluten extraction and developed gluten based edible film. The wet and dry gluten yield of C-306 cultivar was significantly higher than that of RAJ-3765. Five glycerol concentrations viz. 3, 4, 5, 6 and 7 g were tried for film formation and developed films were then compared. Film thickness was independent on glycerol concentration...
