Heavy metal biosorption by biomass of Ochrobactrum anthropi producing exopolysaccharide in activated sludge
(Elsevier Sci Ltd, 2003)The removal of chromium, cadmium and copper, toxic metals of high environmental priority due to their toxicity, from dilute aqueous solutions has been studied in the present work, applying a dead exopolysaccharide producing ... -
Isolation and characterization of antioxidant phenolic compounds from the aerial parts of Hypericum hyssopifolium L. by activity-guided fractionation
(Elsevier Sci Ireland Ltd, 2003)Dried methanol extract of Hypericum hyssopifolium subsp. elongatum var. elongatum was dissolved in distilled water, and then fractioned by re-extracting with petroleum ether, chloroform, and ethyl acetate, subsequently. ... -
Oxalotrophic bacteria
(Elsevier, 2003)Oxalic acid and its salts are widespread in nature, as they are produced by many species of plants, algae and fungi. The bacteria, which are capable of using oxalate as a sole carbon and energy source, are described as ... -
Occurrence of resistance to antibiotics, metals, and plasmids in clinical strains of Staphylococcus spp
(Elsevier Science Inc, 2003)Background. Presence of staphylococci resistant to antibiotics is of concern, as is the possible spread of resistance determinants among Staphylococcus species. During the past several years, a series of staphylococcal ... -
Cultivation of oyster mushroom on waste paper with some added supplementary materials
(Elsevier Sci Ltd, 2003)Spawn running, pin head and fruit body formation, and mushroom yield of oyster mushroom (Pleurotus ostreatus) on I waste paper supplemented with peat, chicken manure and husk rice (90 + 10; 80 + 20 w.w) were studied. The ... -
Antifungal activities of the leaves of three Pistacia species grown in Turkey
