Box 56, Biocenter 1, FI 00014 University of Helsinki, Finland Email: [email protected] Abstract: To find out ability of fourteen basidiomycetes and four ascomycetes strains to grow in the presence of synthetic colour dyes and to degrade them, fungi were ...

decolorization of remazol brilliant blue r (rbbr) by trametessp. pellets was studied in a batch reactor. dye removal process was performed in shaken flasks which contained 100 ml of rbbr aqueous solution and fungal pellets. the process was followed for 48 h and the dye removal was analyzed at a visible spectrum of 590 nm. response surface methodology (rsm) employing box behnken design at three ...

introduction: discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. the aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. materials & methods: this study was performed experimentally and in laboratory scale. in this re...

BACKGROUND Studies were carried on the decolorization of the textile dye reactive blue 19 (RB 19) by a novel isolate of Coprinus plicatilis (C. plicatilis) fungi. We describe an in vitro optimization process for decolorization and its behavior under different conditions of carbon and nitrogen sources, pH, temperature and substrate concentration. RESULTS The optimal conditions for decolorizati...

In the present study, a crude laccase preparation from Pleurotus ostreatus was successfully immobilized on perlite, a cheap porous silica material, and tested for Remazol Brilliant Blue R (RBBR) decolourisation in a fluidized bed recycle reactor. Results showed that RBBR decolourisation is mainly due to enzyme action despite the occurrence of dye adsorption-related enzyme inhibition. Fine tunin...

In many industrial areas such as in food, pharmaceutical, cosmetic, printing, and textile, the use of synthetic dyes has been integral with products such as azo dye, anthrax, and dyestuffs. As such, these industries produce a lot of waste by-products that could contaminate the environment. Bioremediation, therefore, has become an important emerging technology due to its cost-sustainable, effect...

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...

Laccase production by Pycnoporus sanguineus RP15 grown in wheat bran and corncob under solid-state fermentation was optimized by response surface methodology using a Central Composite Rotational Design. A laccase (Lacps1) was purified and characterized and the potential of the pure Lacps1 and the crude culture extract for synthetic dye decolorization was evaluated. At optimal conditions (eight ...
