The aim of this article is to propose a novel type of a nanofluid that contains both nanoparticles and motile (oxytactic) microorganisms. The benefits of adding motile microorganisms to the suspension include enhanced mass transfer, microscale mixing, and anticipated improved stability of the nanofluid. In order to understand the behavior of such a suspension at the fundamental level, this arti...
In this paper, the bioconvective flow in a porous square cavity containing oxytactic microorganism in the presence of chemical reaction is investigated. The bioconvection flow and heat transfer in porous media are formulated based on the Darcy model of Boussinesq approximation. The governing partial differential equations are solved using the Galerkin finite element method. The computational nu...
Thermal energy management associated with the transmission of heat is one main problems in many industrial setups (e.g. pharmaceutical, chemical and food) bio-engineering devices hospital ventilation, heating, cooling devices, exchanger drying food, etc). The current study aims to examine thermo-bioconvection oxytactic microorganisms taking place a nanofluid-saturated needle magnetic field. Ste...
the development of reliable processes for the synthesis of nanoparticles is an important aspect of nanotechnology. biologically synthesized nanoparticles could have innumerable applications in different areas such as reception, catalyzers, biolabellers, etc. in the present review, we emphasize the richness of the microbial world which encompasses a plethora of endophytic entities as an emerging...
today oil removal from contaminated soil by new methods such as bioremediation is necessary. in this paper, the effect of chemical fertilizers and aeration on bioremediation of oil-contaminated soil has been investigated. also the control group, (bioremediation of petroleum hydrocarbons in contaminated soil without treatment by chemical fertilizers and aeration treatment was examined. the cond...
methods for measuring toxicity or respiratory activity of microbial cultures can be used as tools for assessing the presence of chemicals and their impact on the streams. the proposed toxicity test is based on the respirometric characteristics of the bacteria according to the principals of biolog’s microplate system. as the microorganism are utilizing the carbon source (peptone), the reductio...
Biodegradation is defined as the biologically catalyzed reduction in complexity of chemical compounds [1]. Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms [2]. When biodegradation is complete, the process is called "mineralization". However, in most cases the term biodegra‐ dation is generally used to describ...
