The extent of cephalosporin C(CPC) production in producing strains is related with the expression or inhibition of the relevent genes. The goal of this study was manipulate of the producing strain in order to increase its CPC production. Acremonium chrysogenum DSM 2399 is used as parent strain. Mutagenesis is performed on solid form of optimized production media. UV ray and NTG (with ...
There are several reasons for using the unification of exchange rate policy, which is usually associated with the devaluation.The extent of these policies' influences on the economy is very extensive, especially when the economy is relying on single-product exports and has high foreign-exchange reserves. These policies affect the demand side of the economy through the exports and imports channe...
abstract background and purpose: since protein a is considered an important protein from medical, medicinal, genetic engineering, and biotechnology point of view, the present study attempted to investigate and determine to what extent protein a is produced through regression, in addition to the production conditions of the protein. thus, a figure was introduced as for the estimation of the amou...
Iran with a cultivation area of 45000 ha and production of 150 ton/year is the number one saffron producer in the world. Planting of large size corms will increase flowering, but production of corms (number and size) may be affected by irrigation method or frequency. In this research which is performed in the farm of College of Agriculture, Shiraz University, the effects of method and frequency...

given the strategic remarkable rank of pistachio in non-oil exports, inputs’ management in its production is so important. as the scarcest input in agricultural sector, water is considered to be among the most important inputs of pistachio production.water inadequate supply and limate conditions increase water demand in pistachio growing areas. it is necessary to determine the real value or pri...
in many studies, topographic factors have been considered as an important factor in establishing the vegetation in different ecosystems. so, it affects vegetation composition and diversity by influencing soil moisture, fertility and soil depth. the aim of this research was to investigate the effects of slope, elevation and geographical aspects on species growth, forage production and vegetation...
introduction: science production is one of the main dimensions of sustainable development in any country. thus, universities as the major centers for science production play a key role in development. the present study aimed to assess the trend of science production in iran’s type i universities of medical sciences from 2007 to 2012. method: in this study, the universities’ scores of empowering...
The sustained production of sufficient forage is critical to advancing ecosystem-based management, yet factors that affect local abundances and habitat conditions necessary support aggregate remain largely unexplored. We quantified suitable in the Chesapeake Bay its tidal tributaries for four key fishes: juvenile spotted hake Urophycis regia , spot Leiostomus xanthurus weakfish Cynoscion regali...
