plants are the most sources for cadmium enters to human food and this element in food regime may be a serious threat to human health. thus, the effect of azotobacter inoculum (azotobacter chroococcum), mycorrhiza fungi (glomus intraradaices) , zinc sulphate and urea on cadmium convertation and growth parameters of fenugreek medicinal plant (trigonella foenum gracum l.) in cadmium polluted soils...

for gen. sp. 13BJ). The most noteworthy were the results for A. beijerinckii, A. junii and gen. sp. 13BJ. Whereas the former two species included both susceptible and resistant strains all eight strains of gen. sp. 13BJ yielded MICs 16 mg/L. It has recently been shown that therapy with colistin can be compromised by the selection and spread of colistin-resistant A. baumannii strains. Our data f...

Cassava constitutes an abundant substrate in tropical regions. The production of butanol in ABE fermentation by Clostridium beijerinckii BA101 using cassava flour (CF) was scaled-up to bioreactor level (5 L). Optimized fermentation conditions were applied; that is, 40℃, 60 g/l CF, and enzymatic pretreatment of the substrate. The batch fermentation profile presented an acidogenic phase for the f...

Extractive butanol fermentation with non-ionic surfactant, a recently explored area, has shown promising results with several advantages but is relatively less investigated. This work reports the extractive fermentation with selected non-ionic surfactants (L62 and L62D) to enhance butanol production using a high-butanol producing strain (Clostridium beijerinckii MCMB 581). Biocompatibility stud...

Alfred Koch has given considerable attention to the subject of nitrogen fixation by bacteria as resulting from their symbiosis with alga~. Many others have also investigated various features of this problem. In spite of all this there are numerous questions which remain unsolved. The use of soil cultures for such studies is objectionable on account of the soil's complexity, its variety of flora...

in order to evaluate the response of quantitative and qualitative characteristics of the isabgol (plantago ovata frosk.) medicinal plant to separate and combined application of urea and biofertilizer an experiment was conducted in a randomized complete block design at the research farm of shahrekord university in 2011. the experimental treatments consisted of control (no urea and biological fer...
