abstract- to investigate the effects of bio-chemical and organic fertilizers on yield and seeds npk contents of pumpkin (cucurbita pepo var. styriaca), an experiment was conducted at the research farm of kurdistan university in 2009 growing season. treatments were included 1) control, 2) seeds inoculated with free-living n fixing bacteria (nfb), 3) seeds inoculated with phosphate-solubilizing b...

The transformation of phosphorus (P) is a major factor of lake eutrophication, and phosphate releasing bacteria play an important role in the release process. Experiments were conducted to investigate P content and characterize phosphate solubilizing bacterial composition at the molecular level in a shallow eutrophic lake and a wetland. Results showed that P concentrations were relatively high ...

The colonic epithelial surface is protected by an inner mucus layer that the commensal microflora cannot penetrate. We previously demonstrated that Entamoeba histolytica secretes a protease capable of dissolving this layer that is required for parasite penetration. Here, we asked whether there are bacteria that can secrete similar proteases. We screened bacterial culture supernatants for such a...

Assessing the ability of soil microorganisms to dissolute poorly soluble native calcite to supply Ca2+ is a new area to be explored in reclaiming sodic soils by supplying adequate Ca2+ and reducing the recurrent sodicity. Hence, the present study aimed to isolate a calcite dissolving bacteria (CDB) from calcareous sodic soils and to understand the mechanism of calcite dissolution. Of the 33 CDB...

The purpose of this study was to assess the total phenol content and invitro antiurolithiatic activity Hibiscus cannabinus extract various fractions. Kidney stones are one most painful prevalent urinary tract disorders. Drug treatment Extracorporeal Shock Wave Lithotripsy (ESWL) used treat kidney stones. Instead dissolving stone, these treatments may cause acute renal damage an increase in ston...

Fast dissolving tablets (FDTs) are a sort of oral strong measurement structure that crumbles or disintegrates rapidly in the cavity, bringing about fast medication retention and beginning activity. These have acquired fame because their benefits over ordinary tablets, including simplicity organization, expanded patient consistence, further developed bioavailability .FDTs can be ready by differe...

There is a discrepancy between in vitro cholesterol dissolving efficacy of methyl-tert-butyl ether (MTBE) and ethyl propionate and cholesterol gall stone dissolution in vivo. This study investigated whether the presence of bile changes the cholesterol dissolving capacity of MTBE and ethyl propionate. The addition of dimethylsulphoxide to MTBE or ethyl propionate was also studied to discover if ...

Recently, we reported the production of Cadmium sulfide (CdS) fluorescent semiconductor nanoparticles (quantum dots, QDs) by acidophilic bacteria of the Acidithiobacillus genus. Here, we report that the addition of inorganic phosphate to Acidithiobacillus thiooxidans ATCC 19703 cultures favors the biosynthesis of CdS QDs at acidic conditions (pH 3.5). The effect of pH, phosphate and cadmium con...
