Experiments were carried out for optimization of conditions for morphogenic callus production and regeneration of carrot (Daucus carota L.) using four cultivated cultivars in Iran. Hypocotyl segments were cultured on medium supplemented with 0.2 mg/l 2,4-D for callus initiation and proliferation. Small portions of calli (25 mg) were cut and transferred to new media with different concentrations...
microbial cells are producers of natural polymers present in plant cells. production of pullulan (an extracellular microbial polysaccharide) by aureobasidium pullularia pullulans (p. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. pullulan formation obeyed a growth and non-growth associated term. phb (polyhydroxybutyrates) an intracellular biopolyme...
Periwinkle (Catharanthus roseus L., Apocynaceae) contains more than 130 different terpenoid indole alkaloids (TIAs), of which two dimeric alkaloids, Vinblastine and Vincristine, have antineoplastic activity and are useful in treatment of various cancers. Specific production of some alkaloids in differentiated tissues such as leaf and stem led to use direct regeneration of explants in order to i...
چکیده : نظریه ی شیوه ی تولید آسیایی ، اولین بار توسط مارکس و سپس در تأیید نظریات او ، در آثار انگلس مطرح شد . این نظریه علاوه بر شیوه تولید ، به بحث درباره ی ماهیت دولت در جوامع آسیایی می پردازد . در این پژوهش ، وجه تولید آسیایی و نظریات پیرامون آن در توسعه نیافتگی ایران ، مورد بحث و بررسی قرار می گیرند . مهمترین نظ the asian production theory was first introduced by marx and then was suppo...

Based on the seamless learning approach (Wong, 2012), this paper illustrates how media competence can be developed, what didactic design is necessary, and what features this design possesses for teaching media competence at university. The ‘Natural History Museum Berlin project’ is considered as an example of this. In this project, during the 2009 summer term, students at the Carl von Ossietzky...
Though recent advancements in media and computing technologies have fostered greater instructor adoption of student media assignments, few studies have examined the role these projects play in the development of student media production skill sets. This study surveyed 12 first year college students in a postsecondary education class, each responsible for producing a digital story project commun...
The composition of cultivation media in relation to strain development for industrial application is reviewed. Heterologous protein production and pentose utilization by Saccharomyces cerevisiae are used to illustrate the influence of media composition at different stages of strain construction and strain development. The effects of complex, defined and industrial media are compared. Auxotrophi...
Background: This study quantified the effect of four popular culture media in a biodiesel production study on the qualitative and quantitative lipid content, dry biomass, and lipid productivity of Nannochloropsis oculata. Methods: Culture of microalgae was done separately in Walne, F/2, Sato, and TMRL media. In the logarithmic and stationary growth phases, biomass production and lipid accumulat...
