Synthesis, Characterization and Antibacterial Activity of Silver Nanoparticles from Red Algae, Hypnea musciformis
In the present study, silver nanoparticles (SNPs) were synthesized using broth of red algae Hypnea musciformis as reductant by a simple and eco-friendly route. The synthesized SNPs have been well characterized by using various analytical techniques, Zeta potential, Transmission Electron microscopic (TEM), X-ray diffraction (XRD), FTIR and further confirmed by X-ray photoelectron spectrum (XPS)....
متن کاملAntibacterial and antioxidant activities of the red algae Hypnea charoides from coasts of Chabahar
Background and objectives: Marine macro algae are one of the most economically important resources of the oceans which contain important biologically active secondary metabolites. So they can be widely used in various applications. Due to the limited research work on the bioactive metabolites from Iranian algae, the red seaweed, Hypnea charoides, collected from interti...

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 اولMinor polysaccharidic constituents from the red seaweed Hypnea musciformis. Appearance of a novel branched uronic acid.
Two polysaccharide fractions isolated from Hypnea musciformis after room temperature- and hot water extraction, soluble after KCl precipitation of the more abundant carrageenans, were subfractionated by ion-exchange chromatography eluting with increasing concentrations of NaCl. The lowest NaCl concentration (0.2M) eluted agarans. The dl-hybrids (or mixtures) eluted at intermediate concentration...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
