Immobilization of brewing yeast onto a cellulose-based carrier obtained from spent grains, a brewing byproduct, by acid/base treatment has been studied in a continuously operating bubble-column reactor. The aim of this work was to study the mechanisms of brewing yeast immobilization onto spent grain particles through the information on physicochemical surface properties of brewing yeast and spe...

This study introduces the novel HAMBgR process (Hybrid Adsorption Membrane Biological Reactor) and presents an application for the efficient removal of perchlorate from contaminated waters. This process combines the economic advantages of a microbiological treatment with the reliability of a physicochemical process. Batch isotherm experiments show that the ion-exchange adsorbents from this stud...

The review brings a comprehensive survey of recent developments and applications of high performance capillary and microchip electroseparation methods (zone electrophoresis, isotachophoresis, isoelectric focusing, affinity electrophoresis, electrokinetic chromatography, and electrochromatography) to analysis, micropreparation, purification, and physicochemical and biochemical characterization o...

this study examined the adsorption behavior of two cationic dyes used in textile industries (cibasic red 46 and ci basic blue 3) on tunisian clay used in pottery. the ability of pottery clay to remove thebasic dyes from aqueous solution was compared to that of the commercial powdered activated carbon (pac)and raw clay. physicochemical characteristics of these adsorbents were performed by boehm ...

Key words: soil-water transport, van Genuchten model, petroleum hydrocarbons In modeling a phytoremediation strategy, the transport and fate processes of soil water are influenced by subsurface groundwater flow, precipitation events, microbial activity, and transpiring vegetation. This transport is modeled in a variably saturated environment in a vertical dimension and is represented by a Richa...

in this work, we report a new well dispersed molybdenum complex attached through the mediation of aminopropylsilyl groups on the surface of multi-walled carbon nanotubes (mwcnts). the prepared hybrid nanomaterial was characterized with different physicochemical methods such as fourier transform infrared and atomic absorption spectroscopies, transmission electron microscopy, energy-dispersive x-...

Cellular interaction and in vitro antitumor activity of a polymeric prodrug of mitomycin C (MMC), mitomycin C-dextran conjugate (MMC-D), were studied in relation to its physicochemical characteristics. MMC-D with cationic and anionic charges were examined. The cationic MMC-D was synthesized using a spacer, epsilon-aminocaproic acid and dextrans with molecular weights of 10,000, 70,000, or 500,0...

The objectives of the present work give results view some physicochemical, chemical and biological-chemical methods for heavy metals removal from Acid Mine Drainage (AMD). background studied physicochemical was adsorption by turf, precipitation neutralization with NaOH. principles were bioprecipitation applications sulphate-reducing bacteria (SRB), sorption bacterially produced iron sulphides b...
