Biodegradation of phenol in the presence of glucose as a supplementary substrate was investigated with mixed microbial consortium isolated from waste effluent of coke-steel factory. Batch experiments were carried out at room temperature and pH value of 7. Initial phenol and glucose concentrations were in the range of 25-1000 mg/l and 500-3000 mg/l, respectively. In a dual substrates system the ...
Candida tropicalis isolated from acclimated activated sludge was used in this study. Cell suspensions with 5 x 10(7) cells ml(-1) were irradiated by using a He-Ne laser. After mutagenesis, the irradiated cell suspension was diluted and plated on yeast extract-peptone-dextrose (YEPD) medium. Plates with approximately 20 individual colonies were selected, and all individual colonies were harveste...
BACKGROUND The main objective of this study was to examine the photocatalytic degradation of phenol from laboratory samples and petrochemical industries wastewater under UV radiation by using nanoparticles of titanium dioxide coated on the inner and outer quartz glass tubes. METHOD The first stage of this study was conducted to stabilize the titanium dioxide nanoparticles in anatase crystal p...
Abstract Introduction: Phenol is amongst the dangerous environmental pollutants, which due to its presence in the industrial effluents, should be removed. Objective: The aim of this study was to evaluate the efficiency of catalytic ozonation by calcined scallop shell as a catalyst in the removal of phenol Materials and Methods: Scallop shells were collected from the coast of Caspian Sea in G...
