This paper aims to reduce the gap between intensified innovative process designs and application of enzyme technologies at an industrial scale that often take full advantage microreactor systems. Soybean potato processing waste was used as source peroxidase in both free immobilized form for biodegradation Acid Violet 109 anthraquinone dye (AV109) a PTFE (polytetrafluoroethylene) which is 0.5 mm...

background and purpose:organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. the aim was to evaluate the performance nanoscalezero-valent iron (nzvi) in the removal of dye acid red 18 (ar18) from aqueous solutions. materia...

Biodegradation of Navy N5RL1, a widely used acidic azo dye in carpet industry, was studied by bacterial strain isolated from the dye-contaminated soil collected from a carpet industry premises located in Bhadohi, Sant Ravidas Nagar and Uttar Pradesh, India. The isolated strain was identified as Staphylococcus saprophyticus BHUSS X3 on the basis of morphological, biochemical and 16S rRNA gene se...

The ability of some bacteria and filamentous fungi to degrade aniline and its derivatives was reported earlier in the literature. However, there was no information about the biodegradation of aniline by yeast strains. The present work is focused on yeast strain Candida methanosorbosa BP-6 which was isolated from the wastewater pool of the old dye factory "Boruta" in Zgierz by enrichment techniq...

releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...

We developed a new screening method for potential wood preservatives based on decolorization of the dye Remazol Brilliant Blue R by extracellular oxidative agents produced by wood decay fungi. Oxidative biodegradation of lignin yielded decolorized zones around and under fungal cultures on a dyed agar medium. Inhibitory effects were detected by direct observation and measurement of the decoloriz...

among the 30 strains of moderately halophilic bacteria isolated from the salty effluents of textile industries around qom city in central iran, a gram-negative rod shape bacterium designated as strain ip8 showed a remarkable ability in decolorizing of azo dyes over wide ranges of ph (7-11) and temperature (25-45 ºc), in presence of nacl and na2so4 (0.5-1.5 m) under anaerobic and aerobic conditi...

Synthetic dyes released by various industries pose a real concern to the environmental safety. Existing physico-chemical methods of dye removal from effluents suffer from severe constraints like low efficiency, high operational cost and large amount of sludge generation. Over the last two decades, considerable work has been done with the goal of using microorganisms as bioremediation agents in ...

the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...
