Experimental Study and Numerical Modeling of CO2 Bio-Fixation in a Continues Photobioreactor
A dynamic numerical model was developed to predict the biomass concentration, pH, and carbon dioxide fixation rate in the continuous culture of cyanobacteria in a photobioreactor. The model is based on the growth rate equation of microalgae combined with mass transfer equations for gas and liquid phases in the photobioreactor as well as thermodynamic equilibrium of inorganic carbon ions in the ...
متن کاملDark Carbon Fixation: An Important Process in Lake Sediments
Close to redox boundaries, dark carbon fixation by chemoautotrophic bacteria may be a large contributor to overall carbon fixation. Still, little is known about the relative importance of this process in lake systems, in spite the potentially high chemoautotrophic potential of lake sediments. We compared rates of dark carbon fixation, bacterial production and oxygen consumption in sediments fro...
متن کاملتثبیت پتاسیم و ارتباط آن با خصوصیات فیزیکی، شیمیایی و کانی‌های رسی خاک‌های آهکی دشت کاکان، استان کهگیلویه و بویراحمد
Potassium fixation is one of the most important factors influencing the availability of this ion for plants. This research was carried out to evaluate the relationship between potassium (K) fixation with some physical and chemical characteristics of soils and clay minerals and to investigate the effect of the dry and wet cycle on potassium fixation in Kakan Plain, in Kohgilouye & Boyerahmad Pro...
متن کاملStudy on Synthesis and Characterization of Unsaturated Poly (ester-amide) as Bone Fixation Materials
A new type of unsaturated poly ester-amide was prepared by melt polycondensation and characterized completely. Influence of heat treatment conditions and cross-linking content on mechanical and degradation properties of unsaturated polyester-amide were studied. Results suggested that the newly synthesized unsaturated poly(ester-amide) possessed good heat stabilization properties. Mechanical...
متن کاملRelationship between Nitrogen Fixation and Carbon Metabousm in Legumes: a Review
The process of nitrogen fIXation by the legumes imposes carbon (C) energy burden on the plant. The photosynthate translocated from the leaves provides carbon skeleton, reducing power and energy required for the symbiotic nitrogen fIXation. Sucrose from the shoot is converted to organic acids, principally dicarboxylates that are supplied to bacteroids to provide reductant for the support of key ...
متن کاملEffects of drought stress on legume symbiotic nitrogen fixation: physiological mechanisms.
Drought stress is one of the major factors affecting nitrogen fixation by legume-rhizobium symbiosis. Several mechanisms have been previously reported to be involved in the physiological response of symbiotic nitrogen fixation to drought stress, i.e. carbon shortage and nodule carbon metabolism, oxygen limitation, and feedback regulation by the accumulation of N fixation products. The carbon sh...
