A mathematical model has been analyzed for in-situ bioremediation with the purpose of remediating organic contaminated soil. Oxygen rich water when passed through the porous media of soil activates the aerobic microorganisms, leading to the biodegradation of the organic content. The model equations comprise three convection-dispersion partial differential solution of these equations has been co...

current global water shortage and water pollution problem are some of the crucial issues in theworld, especially in the arid zones. the wastewater reuse was investigated the efficiency of fecal coliform(fc) removal using the intermittent media infiltration (imi) with varying soil content and natural porousmedia (sand, zeolite, vermicompost and charcoal), and its prediction was introduced by app...

Colloid transport in subsurface has received considerable attention recently because mobile colloids can facilitate the transport of heavy metals in soils to contaminate groundwater. Many studies on colloid mobility in the subsurface consider soils as well-defined porous media. Though similar in many aspects, soils are different from well-defined porous media. The authors emphasize the impacts ...

The effect of growth medium and incubation time were investigated by determining the number of colonies that were visible on triplicate plates of three different media on daily intervals. The viable counts were significantly different between the three different media even after the first day and this continued for seven days. Colony counts on the three media reached their maximum on the third ...

various basidiomycetes and deuteromycetes, grown in liquid and solid culture media, were compared for their laccase-producing ability and for the inducing effect of soil and agricultural residues on laccase production. laccase activity in extracts of all solid media was higher than that of the liquid media. in liquid cultures, fungal laccase activity in ex-tracts of pea (pisum sativum) straw-tr...

In two independent experiments, acclimatized chicory plants were transferred into an aeroponic system and to the soil. Then, the effects of biofertilizer (Nitrokara) and culture filtrate of Piriformospora indica were investigated on some plant characteristics in both aeroponic and soil cultivation system under greenhouse conditions. The plants were foliar sprayed with three different biofertili...

this experiment was carried to find out the effects of foliar fertilization and growing media on some of vegetative and reproductive traits of the new vegetable pepino (solanum muricatum) in a pot culture in outdoor space during five month period in mashhad. foliar fertilization treatments were used in this study including foliar fertilization once every three weeks, once a week and control (no...
