the potential of marine actinobacteria particularly streptomyces as a single cell protein (scp) feed for the growth of ornamental fish, xiphophorus helleri has been investigated. the streptomyces strains used as scp were isolated from the marine sponges, namely callyspongia diffusa , mycale mytilorum , tedania anhelans and dysidea fragilis . six scp feeds were prepared and their effects were co...

the mechanism of the genesis and development of obesity is not yet known. in particular, it is not known whether the main reason is and increase in energetic efficiency, i.e. better utilization of food consumed, or hyperplasia. this study was undertaken to throw some light on this subject. obesity was produced by chemical methods, i.e. by injections of gold-thioglucose and mono-sodium glutamate...

wheat and barley are the main crops in iran and has multiple uses. research suggests that subsistence food crops such as wheat and barley has a special place in low-income countries. however, to achieve maximum efficiency for a sustainable agriculture must be able to obtain agricultural inputs such as land. kerman province is one of the provinces with high production of these products. accordin...

in this study, total factor productivity growth of iran’s pulses (including irrigated pea, dry pea, irrigated lentil, dry lentil, irrigated soybean, dry soybean and irrigated bean) during of farming years 1989-1990 though 2007-2008 had been analyzed, using nonparametric malmquist approach. so, amounts of inputs usages include seeds, fertilizers, dung, poison, herbicide, labor, water and acreage...

13 The identification of cellular objectives is one of the central topics in the research of 14 microbial metabolic networks. In particular, the information about a cellular objective is 15 needed in flux balance analysis which is a commonly used constrained-based metabolic 16 network analysis method for the prediction of cellular phenotypes. The cellular objective 17 may vary depending on the ...
